Description

Technical Field

[0001] This invention relates to a comfortable men's lengthening underwear that can solve the problem of phimosis and alleviate the concerns of countless men. Background Technology

[0002] 1. Traditional underwear will develop an odor if worn for more than one day, especially in summer when the odor is still noticeable even after wearing it for two hours. This odor is generally caused by a series of chemical changes resulting from the growth and fermentation of bacteria in the humid environment of the underwear, mixed with residual urine odor and secretions. To date, there is no way to completely solve this problem. 2. Traditional men's underwear is hot and stuffy, providing only basic protection and offering no benefit to men's health. For example, prolonged exposure of the testicles to body temperature can reduce sperm motility, leading to numerous cases of infertility. Traditional underwear is also of no help to men with phimosis (pseudo-phimosis), as the hot and humid environment can accelerate the growth of bacteria inside and make the odor increasingly strong. 3. Male phimosis can also cause a series of problems, such as premature ejaculation, impotence, kidney deficiency, urinary tract infection, and the smegma under the foreskin may also infect women, causing various health problems. Short penis can also cause men to lose confidence, leading to disharmony in marital relationships and countless family breakdowns. 4. Regardless of age or gender, there will always be 1-2 drops or more of urine left over when urinating. This urine will eventually be absorbed by underwear, making the underwear even more damp and smelly, making it unbearable to be near it. 5. Over the decades, numerous patents have emerged worldwide, yet none have perfectly achieved the functions of cleanliness, comfort, and prevention of various male diseases of different sizes. For example, patent application number 201610556304.5, titled "A Penile Traction Device," only mentions three locking rings: one for the scrotum, one for the glans, and one for the base of the penis. It claims to keep the glans exposed by pulling on the base of the penis and scrotum, but there's nothing to fix or pull on the front of the glans. Pulling only on the base of the penis cannot sustainably retract the foreskin. Once the penis becomes flaccid, it pulls the glans and foreskin back together, and the foreskin quickly returns to its original position, covering the glans again. It completely fails to provide long-term exposure of the glans and is only suitable for providing some pulling effect during penile erection. This simple structure only leads to… The following are some consequences: Ordinary circumcision rings, due to their ring-shaped, sheet-like, or life-ring-like structure, do not conform to the coronal sulcus, resulting in a small force-bearing area and high pressure. This can cause severe pain in the glans, penis, and scrotum, rendering them commercially worthless. Wearing them makes normal work and daily life impossible, causing excruciating pain every time one urinates. Before each urination, the circumcision ring at the coronal sulcus must be forcefully pulled up and down, causing destructive constriction to the glans and penis, potentially leading to swelling of the coronal sulcus. Another example is patent number 202011324344.X, patent name: Multi-piece sewn foreskin anti-reversion underwear and its... The manufacturing process of this patented product involves using a specially shaped piece of fabric to create underwear with a penile opening. The opening is coated with silicone, which stretches to cover the foreskin and prevent it from retracting and covering the glans. However, the diameter of the silicone ring in this patent is fixed and cannot be changed. This often causes the glans to retract into the penile opening and fail to hold properly. Since the diameter of the penis varies greatly between erect and flaccid states, a fixed-diameter silicone ring is clearly unsuitable for men of various sizes. Even more critically, this design has a significant flaw: while it works when the penis is flaccid, once erect, the silicone at the glans will stretch... Pulling back the foreskin causes severe pain to the glans because the elastic space at the front of the underwear, which is fixed in size, cannot allow the erect penis to extend comfortably outward. Another example is patent application number 200310112461.X, patent name: Automatic Centering Three-Dimensional Men's Underwear. This underwear uses molding to create an egg-shaped, outwardly protruding groove. This groove has no rigidity; it neither secures the genitals nor improves breathability. The automatic centering is ineffective; in fact, the penis still moves around freely in the pocket and cannot be properly centered. Yet another example is patent number 202280099483.8. Patent Title: Men's Underwear and Penis Fixation Support Device. This patent merely sets two fulcrums at different heights on the penis to temporarily fix its position and solve the problem of pseudo-phimosis (or redundant foreskin). In fact, this patent cannot solve the problem of long-term wear, nor can it solve the problem of redundant foreskin, because there is no external force to stretch the glans. There is only a somewhat flexible penile fixing ring supporting it from below, and it does not hold the coronal sulcus. When the penis is flaccid, the flexible ring cannot fix the penis at all and will obviously slip, causing the foreskin to return to its original position and cover the glans. This patent only works when the penis is erect. The foreskin can only be stretched during erection because the increased displacement caused by the swelling and congestion of the penis during erection is like a force pulling the glans outward, creating an action-reaction effect. This patented design lacks any long-distance elastic structure to pull the scrotum backward; it only has a small rubber band holding the edge of shorts. That small rubber band can only stretch or contract by less than 1cm. It's impossible to achieve a 3-5cm displacement of the foreskin with just 1cm of stretching. Men with phimosis typically have foreskins that are 3-5cm longer than normal, and such a long displacement requires a long-distance stretching structure. 6. Among the thousands of patents related to men's underwear online, none have invented a key structure: the retaining ring design for the coronal sulcus of the glans penis. The following are some common types available on the market, such as... Figure 2 This structure uses a strip or sheet-like fabric with a rope threaded inside. Tightening the structure has a fatal flaw: when tightened, the fabric wrinkles, easily trapping the skin at the coronal sulcus of the glans, causing pain and making long-term wear impossible. For example, patent number 201510620421.9 has a coronal sulcus retaining ring structure as shown in the attached image. Figure 3 As shown in Figure a, several fulcrums hold the coronal sulcus in place, causing pain in the glans penis after several hours of wear due to excessive local pressure caused by the small contact area. In contrast, the irregularly shaped coronal sulcus retaining ring structure designed in patent number 201510620420.4 is shown in the attached figure. Figure 3 As shown in b, there are also multiple contact points, and excessive pressure at each point can cause severe pain in the glans penis; most coronal sulcus retainers on the market use a swimming ring structure, as shown in the attached image. Figure 4As shown, this structure does not perfectly fit the shape of the coronal sulcus. The surface of the retaining ring only has two lines that contact the two surfaces of the coronal sulcus. Both surfaces will have high pressure, resulting in poor wearing comfort. Moreover, the sealed and thick rubber ring will make the entire coronal sulcus not breathable, making it easy for bacteria to grow. Similar patents are common in the market. For example, application number: 202410016498.4, invention name: method and device for stable separation of penis and scrotum. It uses two rings, one to fit the scrotum and the other to fit the base of the penis (not to fit the coronal sulcus to stretch the glans). A penis groove is integrated with the rings to hold the penis. This groove hangs on the waist belt. The function of the groove is only to hold the penis and keep it facing upward. The groove is fixed to the waist belt by two ropes. There is no stretching structure for the glans. This invention only serves to prevent the penis from falling down and contacting the scrotum. It does not have any effect on solving phimosis or penis enlargement. 7. Traditional penile enlargement methods either involve surgery or forcefully pulling the glans penis with specialized instruments, causing significant pain to men and severely impacting their normal work and life. Penile injury from this forceful pulling is sometimes unavoidable, with side effects including insomnia, for example... Figure 5 A refers to the design drawing with application number 20211017920.5, which describes a powerful pulling device made of metal structures such as screws, springs, and gears. Made of steel, it is very unfriendly to delicate skin. Summary of the Invention

[0003] To solve all the above problems at the same time, this invention redesigns the underwear using an innovative coronal sulcus retainer structure, an innovative glans stretching method, and an innovative scrotum protective mesh fabric. In addition to being comfortable to wear and solving the problem of phimosis, this invention can also increase penis size, prevent premature ejaculation, and benefit all men in the world. Technical solution

[0004] Through methods such as fabric design, cutting design, styling design, and mold design, a hole is made in the front of the men's underwear to facilitate the exposure of the penis, and another hole is made in the lower front of the underwear to facilitate the exposure of the scrotum, as shown in the attached image. Figure 6 As shown in Figure a, or with only one large hole in the front of the underwear, allowing the penis and scrotum to pass through and be exposed simultaneously, as shown in the attached figure. Figure 6 As shown in Figure b, a three-dimensional design is used to create a non-closed coronal sulcus retainer ring that conforms to the shape of the coronal sulcus. The retainer ring has holes or buckles at both ends, allowing it to be fastened to different positions to improve the tension on the glans and make it suitable for all men. It can perfectly fit penises of different sizes, lengths, and glans girths, ensuring comfortable wear for any man. This design can be made into four-corner briefs or three-corner briefs. By using the elastic retainer ring on the coronal sulcus to tighten the glans and continuously pull it upwards, the foreskin and glans are continuously separated, achieving a male growth effect and solving the problem of phimosis. This brings great benefits to men with short penises and phimosis. Specific implementation methods

[0005] 1. Design and implementation of an elastic retaining ring for the coronal sulcus of the glans penis: as shown in the attached document. Figure 1 As shown in the attached image, the most comfortable clasp was designed using 3D design software. Figure 1 The non-closed, two-ended open coronal sulcus elastic retainer structure shown in Figure a allows for a perfect fit to the coronal sulcus surface. When worn, the two adjacent sides of the retainer's longitudinal cross-section (in contact with the skin of the coronal sulcus) form a "7" shape (as shown in the attached figure). Figure 1 b's ④ and appendix Figure 3 As shown in Figure c①, the top of the "7" shape is pressed against the surface of the glans penis, and the sides are pressed against the surface of the penis. This three-dimensional structure extends from the lowest point of contact with the coronal sulcus (the apex of the corner of the "7" shape). Figure 5 b's ①) to the highest point ( Figure 5 b) is a spiral ascending structure, and the above longitudinal section (attached) Figure 3 c) The entire structure uses the same spiral ascent, and the highest point of the spiral ascent is the starting position of the circlip opening (see attached diagram). Figure 5 (②), extending 1-10cm from the starting position as the extension segment (as shown in the attached document). Figure 1 c of ⑩), a hanging hole is provided at the end of the extension section (attached). Figure 1 a) ②) or raised buckle (attached) Figure 8 (a) ④), the longitudinal section at the end of the extension is a rounded rectangle or an ellipse (as shown in the attached figure). Figure 1 (a) The above-mentioned coronal sulcus elastic retainer structure adopts a two-end open design, or a closed-loop non-open design. When the two-end open design is adopted, the ends of the extensions at both ends have holes or fasteners. When the closed-loop non-open design is adopted, there is only one extension (as shown in the attached diagram). Figure 4 (c, ⑥) The end of this extension also has a hole or fastener. Regardless of whether the retaining ring is closed, the aforementioned retaining ring with the extension can also be in the shape of a lifebuoy (as shown in the attached). Figure 4 c) Flat strip shape or other arbitrary shape, that is, the longitudinal section of the retaining ring is circular, elliptical, rectangular, rounded rectangle or other polygonal; the elastic retaining ring material mentioned above can be one of the following: spandex, rubber, latex, silicone, TPE, TPR, TPU and any elastic material that is non-toxic to the human body. The extension section and the retaining ring are made of the same soft elastic material in one piece. The elastic retaining ring has tiny vent holes (as shown in the attached image). Figure 1 a's ③ and appendix Figure 4 (c) (⑤) Prevent the skin in the coronal sulcus from becoming stuffy and hot, which can lead to bacterial growth. 2. Underwear structure design and implementation:

[0006] The underwear has 1-2 holes at the front and bottom. If there are 2 holes, the upper hole at the front is for penile penetration, and the lower hole is for scrotal penetration, as shown in the attached image. Figure 6 As shown in Figure a, if only one hole is made, this hole is located at the bottom of the underwear and is a hole through which both the penis and scrotum pass, as shown in the attached figure. Figure 6As shown in Figure b, a scrotal pouch is attached to the bottom of the underwear. The scrotal pouch is made of mesh fabric with a mesh opening diameter greater than 0.3mm, allowing for better ventilation and breathability of the scrotum, which can improve sperm motility. The underwear can be designed as either boxer briefs or four-corner briefs. To enhance the appearance of the underwear, an outer lining layer is included (see attached figure). Figure 6 ① Holes are cut at appropriate locations on the outer lining layer to allow for the installation of fastening devices. These devices tighten and secure the coronal sulcus retainer ring, preventing it from falling off. To enhance the underwear's appearance, an outer cover layer is added over the outer lining layer. This outer cover layer conceals the fasteners, resulting in a more aesthetically pleasing overall look, as shown in the attached image. Figure 7 As shown in ① of a, the underwear can be designed so that the coronal sulcus retainer can be released when urinating, as shown in the attached document. Figure 7 The zipperless (Hook and loop, magnetic snap) or coronal sulcus retainer design shown in Figure a, or the design that does not require unfastening the retainer ring when urinating, is attached. Figure 7 Model b features a zipper (or Velcro, magnetic closure). Without needing to unfasten the coronal sulcus retainer, simply open the entire outer liner from top to bottom. The penis is then pulled by the retainer and can be lowered from an upright position for easy urination. After urination, simply lift the outer liner and close the zipper (or Velcro, magnetic closure) as shown in the attached image. Figure 7 As shown in b⑤, the outer lining layer is fitted to the underwear. When the zipper is closed, the outer lining layer, along with the penis, stands upright and is stably positioned in the front of the underwear, facilitating normal daily activities and movements without obstructing the crotch. A moisture-absorbing layer can also be designed on the inner side of the outer lining layer near the glans, as shown in the attached image. Figure 7 As shown in b, ⑥, this design allows for timely absorption of residual urine after each urination, keeping the glans dry and preventing bacterial growth. The absorbent layer is made of disposable material and can be changed once or multiple times a day. For the zipperless (Hook and loop, magnetic snap) version, the coronal sulcus clip needs to be unfastened. An opening is provided on either side of the outer lining to allow the penis to protrude from that side. After urination, it can be reattached. The outer layer of the aforementioned underwear can be a piece of fabric of any shape, or it can be an outer pair of shorts (as shown in the attached image). Figure 12 (as shown in a), outer trousers (as attached) Figure 12 (as shown in b) or an outer skirt, wherein the outer trousers, outer shorts or outer skirt share a waistband with the underwear of the present invention. The underwear may be designed as triangular or four-cornered underwear. 3. Design and implementation of the fastening device:

[0007] Because the size of the glans penis varies among men, a snap-on fastening structure must be designed to accommodate various glans sizes. This structure should be easy to install and remove while being extremely compact and space-saving. The outer lining of the underwear features 1-10 rows of holes at different heights, with each row consisting of two holes. Alternatively, two holes can be combined into one (see attached image). Figure 8 (As shown in ⑧ of d), the extension of the elastic retaining ring can easily pass through the hole, and one fastening device is symmetrically installed on each of the two sides of each row of holes (as shown in the attached diagram). Figure 1 (⑦), the symmetrical fastening device is shaped like an inverted "V" (as shown in the attached image). Figure 8 b), arranged in a positive "eight" shape or a "one" shape. The fastening device can also be designed in an asymmetric arrangement, such as a "one" shape on the left and a "\" shape on the right (as shown in ⑤ of Attachment Figure 8 d), or a " / " shape on the left and a "one" shape on the right (as shown in ⑥ of Attachment Figure 8 d). The fastening device can also be set in any shape at any position on the outer lining layer, as shown in c of Attachment Figure 12 . There is a pentagonal fastening device on the left and a circular fastening device on the right. When worn, the snap ring is put on the coronal sulcus and pulled up. Two ends or one end of the extension section of the snap ring pass through the corresponding opposite holes on the outer lining layer. Since there are holes or buckles on the extension section of the snap ring that can fasten the fastening device outside the outer lining layer, the coronal sulcus snap ring can obtain continuous pulling force. The farther the buckled position is, the greater the pulling force, so it is suitable for smaller penises. And the multiple rows of fastening devices on the outer lining layer are at different heights, suitable for penises with an erection length of 6 - 35 cm or more. For a short penis, such as an erection of only 6 cm, the bottom row of fastening devices can be buckled. For a long penis, such as an erection of 22 cm, the top row of fastening devices can be buckled. If it is necessary to adapt to men with larger sizes, such as a penis erection of 28 cm or even 35 cm or more, higher fastening devices can be designed as required. The fastening device can also be not set on the outer lining layer, but directly set on the belt. When worn, only need to first fasten the elastic snap ring on the coronal sulcus and then pass through the opposite holes on the outer lining layer and directly hang or buckle on the belt (as shown in Attachment Figure 11 ). The above design has a simple structure, is convenient for disassembly and assembly, and can quickly expose the glans and penis when urinating. There is a zipper (magic tape, or magnetic buckle) at the edge of the outer lining layer (as shown in b of Attachment Figure 7 ), or there can be no zipper (magic tape, or magnetic buckle). There is only an opening on any side of the left or right of the outer lining layer for the penis to expose from the side for convenient urination (as shown in ② of Attachment Figure 6 ). The outer lining layer of the underwear and the fastening device can be integrally formed by injection molding to obtain an integrated design.

[0008] To wear, first thread the penis through the corresponding hole in the underwear, then slip the coronal sulcus buckle onto the underwear. The extension of the buckle passes through the holes or single holes in the outer lining. Connect the buckle or hole of the extension to the fastening device on the outer lining or waistband. Close the zipper on the outer lining (if a zipper is installed) to perfectly cover the penis. This design effectively solves the problem of continuous stretching of the glans. Start wearing the underwear when the penis is fully erect, and wear the buckle higher so that the glans receives continuous upward pulling force. When the underwear zipper is tightened, the waistband will generate continuous upward pulling force, controlling the position of the glans and preventing it from falling down. The glans is fixed at a certain height. When the penis is flaccid, the glans is still pulled up in a high position, while the foreskin naturally falls down due to its own weight and the gravity of the suspended testicles. The weight of the testicles will pull the foreskin down, so that no matter how much the man with phimosis moves, the foreskin cannot retract and return to its original position to cover the glans. Wearing the underwear for a long time can achieve the effect of penis enlargement.
