Adjustable Leg Rest Height for 90° Back Pain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back pain relief devices are often fixed in height, making them ineffective for individuals of varying heights, as they do not accommodate the unique anatomical needs of different users.
Innovation Solution
A leg rest device with adjustable height, allowing users to position their legs at a 90° angle, manufactured from lightweight materials and featuring a foldable design with telescoping legs and multiple height settings, ensuring compatibility with various user heights and facilitating easy transportation and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-height device is used, then the device structure is simple, but it cannot accommodate users of different heights
Solution Approach 1:
The device incorporates adjustable height legs that can be modified to different positions, transforming a static structure into a dynamic one. This allows the device to adapt to users of varying heights while maintaining structural simplicity through a straightforward adjustment mechanism.
Solution Approach 2:
The height parameter of the device is made variable through adjustable legs with multiple position settings. This enables the same device to serve multiple height requirements without requiring completely different device designs for each user.
2Adaptability or versatility
If adjustable height mechanism is added, then adaptability to different heights is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism is divided into discrete height positions rather than requiring continuous adjustment. This segmentation simplifies the mechanism by providing specific stop points, reducing the complexity compared to a fully continuous adjustment system while still achieving adaptability.
Solution Approach 2:
The device enables users to independently adjust the height to their preferred position without requiring complex controls or assistance. The self-adjusting nature of the mechanism keeps it simple while providing full adaptability.
3Strength
If heavy materials are used, then device strength is improved, but ease of transportation deteriorates
Solution Approach 1:
The device employs composite construction combining lightweight materials with strategic reinforcement. This allows the overall structure to remain light for easy transportation while specific critical areas maintain sufficient strength through reinforced design or material selection.
Solution Approach 2:
Rather than making the entire device heavy, strength is concentrated in specific local areas where it is most needed. The majority of the structure uses lightweight materials for portability, while key load-bearing components are reinforced to maintain overall device strength.

AI summary
The present invention relates to an apparatus for relieving back pain, the apparatus having a top and a leg assembly for supporting the top when the apparatus is placed on a surface. A method of relieving back pain is also provided, wherein a user adjusts the height of an apparatus according to the user's buttock popliteus length, and lay on the surface and place his/her lower legs or feet on the top of an apparatus such that the knees are bent at substantially 90 degrees and his/her back is flat on the surface.
