Telescopic Penis Extension Rod with Threaded Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing penis extension devices lack flexibility and ease of adjustment to accommodate varying penis lengths, requiring the addition or removal of extension elements for length changes.
Innovation Solution
The device incorporates a joint sleeve with an internal thread, and two telescopic adjustment units – a threaded sleeve and a threaded spindle – allowing for adjustable length by screwing these components in and out, providing a large adjustment area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple rod-shaped extension elements are screwed together to adjust length, then the device can accommodate different penis sizes, but the adjustment process becomes complex and requires adding or removing extension elements
Solution Approach 1:
The extension rod is divided into a base rod and multiple telescopic adjustment units, each with threaded components that can be independently adjusted. This segmentation allows for incremental length changes without requiring complete disassembly or addition of separate elements, simplifying the adjustment process while maintaining adaptability to different penis sizes
Solution Approach 2:
The telescopic adjustment units are nested within each other, with each unit containing threaded sleeves and spindles that fit inside the previous unit. This nested structure enables compact storage when not in use and allows for smooth, continuous adjustment by simply rotating the threaded components, eliminating the need to add or remove separate extension elements
2Reliability
If extension elements are fully screwed in for stability, then the connection is secure, but length adjustment is not possible without disassembly
Solution Approach 1:
The adjustment units incorporate threaded sleeves and spindles that can be dynamically adjusted by rotation. The threads provide mechanical engagement for secure connection when fully screwed in, while allowing for easy adjustment by simply rotating the components. This dynamic mechanism maintains reliability through threaded engagement while enabling simple operation for length adjustment without disassembly
Solution Approach 2:
The threaded spindles and sleeves act as intermediary elements between the fixed base rod and the adjustable extension components. These intermediaries provide the mechanical interface that allows for secure connection through threading while enabling smooth adjustment through rotation, bridging the gap between stability and adjustability
3Length of moving object
If multiple extension elements are used to achieve desired length, then the required length can be obtained, but the device cannot be adjusted while being worn
Solution Approach 1:
The telescopic adjustment units with threaded components enable dynamic adjustment of the extension rod length even when the device is being worn. The user can simply rotate the threaded sleeves or spindles to extend or retract the adjustment units, allowing for real-time length modification without requiring disassembly or addition of separate elements, thus maintaining both the desired length and ease of operation during use

AI summary
The invention relates to an apparatus (1) for permanently extending a penis, which apparatus comprises a support ring (2) and at least two extension rods (3) which are articulatedly fastened to the support ring (2) and are axially resiliently mounted by means of a spring (42) and are longitudinally adjustable, wherein the extension rods (3) comprise: a joint sleeve (10), which is articulatedly connected at one end to the support ring (2); a spring sleeve (34), in which the spring (42) is arranged and which is connected at one end to a coupling element (4) suitable for connecting a fastening device (43) for a penis to the extension rods (3) and for exerting a tensile force on the penis; and at least one rod-shaped telescopic adjustment unit arranged between the spring sleeve (34) and the joint sleeve (10). The problem addressed by the invention is solved in that: the joint sleeve (10) comprises an internal bore (19), in the wall of which an internal thread (19) is formed; a first (20) and a second (25) telescopic adjustment unit are arranged between the spring sleeve (34) and the joint sleeve (10); the first adjustment unit provides a threaded sleeve (20) which has an external thread (21), that is screwed into the internal thread (19) of the joint sleeve (10), and an internal bore (22), in the wall of which an internal thread (23) is formed; the second adjustment unit provides a threaded spindle (25) which, with respect to the threaded sleeve (20), is fitted with an external thread (27) that is screwed into the internal thread (23) of the threaded sleeve (20) and, with respect to the spring sleeve (34), is fitted with a pin (28) projecting into the spring sleeve (34); and the spring (42) is arranged in the spring sleeve (34) between the pin (28) and the coupling element (4).
