Skin Tensioner With Interlocking Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying tension to skin tissue, such as those used in hair transplantation, lack efficient mechanisms to uniformly stretch and maintain tension on the scalp or other body areas, leading to suboptimal results and discomfort.
Innovation Solution
A skin tensioner device comprising interlocking beams with teeth and gears, along with an expandable screw mechanism, that applies and maintains tension by sliding extensions and using pins to pierce the skin, allowing for adjustable and controlled stretching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing tensioning devices are used, then skin tension can be applied, but the tension is not uniformly distributed and cannot be maintained effectively
Solution Approach 1:
The tensioning device is divided into multiple independent beams (first beam, second beam, third beam, fourth beam) that can be adjusted individually. Each beam has separate extensions with teeth that engage with corresponding slots, allowing independent positioning and uniform distribution of tension across different regions of the skin surface.
Solution Approach 2:
The device incorporates adjustable mechanisms with gears and knobs that allow dynamic modification of beam positions and extension lengths. The extensions can slide within slots and be locked at various positions, enabling the tensioner to adapt to different skin areas and maintain optimal tension uniformly across the treatment area.
2Manufacturing precision
If simple tensioning mechanisms are used, then the device structure remains simple, but the precision and control of tension application are insufficient
Solution Approach 1:
The device replaces simple mechanical fastening with a gear-based mechanical transmission system. The gears on the extensions engage with corresponding gear slots, providing precise control over beam positioning and tension application. This mechanical substitution enables fine-adjustment capabilities while maintaining a purely mechanical structure without electronic components.
3Adaptability or versatility
If fixed tensioning devices are used, then the structure is stable, but the adaptability to different skin areas and procedures is limited
Solution Approach 1:
The tensioning device is designed with universal beams that can function in multiple configurations. The first and second beams can work together, as can the third and fourth beams, allowing the device to adapt to various skin areas and procedural requirements. The standardized slot and gear interfaces enable different beam combinations while maintaining structural stability through consistent engagement mechanisms.

AI summary
A device for applying tension to a skin surface is provided. The device includes a first, second, third and fourth beam. Each of the beams has a main body, an extension extending from a first end of the main body and a second extension extending from a second end of the main body. The first end of the third and fourth beams have an opening defined therein and a slot sized to receive either the first extension of the first beam or the second extension of the first beam. The second end of the third and fourth beams have a slot sized to receive the other of the first extension of the second beam or the second extension of the second beam. The first extension of the first beam is slidably positioned within the slot on the first end of the third beam and the second extension of the first beam is slidably positioned within the slot on the first end of the fourth beam. The first extension of the second beam is slidably positioned within the slot on the second end of the third beam and the second extension of the second beam is slidably positioned within the slot on the second end of the fourth beam and the posts of the third and fourth beams extend through the openings on the extensions of the second beam.
