However, in the design of underpants for men, the special and variable structure of the external
male genitals limits the range of innovation; as a result, the extant designs of men's underwear have several notable deficiencies.
In the case of briefs for men, the genitals are better secured but the ventilation is less than satisfactory, leading to health concerns.
Although
boxer shorts solve the ventilation problem, boxer shorts cannot support the weight of the
scrotum and
penis effectively, so the scrotum and penis are neither supported nor secured.
In addition, the penis can vary in size or volume during the span of a day, and such changes may be visible as a bulge in the surface of the clothing.
Obvious movements caused by partial or complete engorgement of the penis can cause embarrassment to the user.
However, the design of Patent JP2007-070785 cannot effectively support the weight of the scrotum.
In addition, because the design of Patent JP2007-070785 applies a traditional
cotton material to cover penis, no breathable space is available for the penis.
Thus the design of Patent JP2007-070785 cannot provide overall breathability for the genitals.
However, the design of Patent CN201479935 provides neither breathable space for the penis nor support for the weight of the scrotum.
However, the breathable shell mold is not flexible.
The design of Patent CN202857839 has a limited accommodating space for the genitals and may not be comfortable for the user.
However, because the inner
crotch covers the genitals entirely, the inner crotch can be considered as briefs sewn into boxer shorts, and this design cannot provide overall breathability for the genitals.
In addition, the inner crotch provides neither sufficient space to accommodate the genitals nor any support for the genitals.
However, the design of U.S. Pat. No. 6,820,284 still applies the traditional
cotton material of underwear to cover the genitals and cannot provide overall breathability for the genitals.
On the other hand, although the supporting element can provide some support for the genitals, the underwear still cannot provide sufficient space for accommodating the genitals.
In addition, the design of U.S. Pat. No. 6,820,284 further cannot conceal physiological changes of the
male genitals.
Similarly, the design of Patent US2010 / 0058517 also applies the traditional
cotton material of underwear to cover the penis and cannot provide overall breathability for the genitals.
In addition, although the inner crotch can provide some support for the genitals, the underwear still cannot provide sufficient space for accommodating the genitals.
In addition, the design of Patent US2010 / 0058517 further cannot conceal physiological changes of the male genitals.
Although the design of the inner crotch integrated with the scrotum bag can provide some support for the genitals, the underwear still cannot provide sufficient space for accommodating the genitals.
In addition, the design of Patent US2005 / 0235399 further cannot conceal physiological changes of the male genitals.
The manufacturing process of Patent US2005 / 0235399 is complicated and requires much manufacturing time.
Furthermore, although the design of Patent US2005 / 0235399 can provide supporting and
breathing effects, it still cannot provide a breathable accommodating space for the penis.
From the above, it is clear that the men's pants of the prior art cannot provide overall breathability, securing and supporting effects for genitals, low manufacturing costs, or sufficient space for accommodating the genitals.
In addition, the previous men's pants further cannot conceal physiological changes of the male genitals.
