Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current curved boards for standing at work cause improper joint bending, leading to stress and discomfort, and are rigid, making it difficult to use a keyboard while rocking, thus reducing work efficiency and increasing physical passivity.
Innovation Solution
A multi-functional curved board with ergonomically designed counter-curve pieces or structures that allow natural foot positioning and flexibility, produced using molding or CNC machining, enabling adjustable rigidity and elasticity, and featuring a convex side for varied exercises and add-ons for enhanced versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a curved board is used for standing, then movement for legs is allowed and numbing is reduced, but joints of ankles and knees bend to wrong position causing stress problems
Solution Approach 1:
The board features different curvature radii in different regions: a first curvature radius in the front region and a second curvature radius in the rear region. This local differentiation allows the front part to support the ball of the foot while the rear part supports the heel, maintaining natural foot alignment and preventing joint stress while still providing leg movement benefits
2Strength
If a rigid curved board is used, then structural stability is maintained, but even tension is caused in legs and muscles making it difficult to work
Solution Approach 1:
The board incorporates a rocking capability that allows dynamic adjustment of the curvature. The rocking movement enables users to vary the points of tension in their legs and muscles, preventing even tension and muscle fatigue while maintaining structural stability through the controlled rocking mechanism
3Ease of operation
If the board is rocked for varying tension points, then muscle tension is varied, but keyboard use becomes nearly impossible and work is interrupted
Solution Approach 1:
The rocking movement is designed to be subtle and controlled rather than extreme. The board can be rocked slightly to vary tension points while maintaining enough stability for keyboard use, allowing users to get the benefits of muscle tension variation without completely disrupting work activities
4Object-affected harmful factors
If counter-curve pieces are attached to ends of board, then foot positioning is corrected and joint stress is reduced, but device complexity increases
Solution Approach 1:
The counter-curve pieces are integrated into the board structure by attaching them to the ends of the curved board. This merging of components creates a unified structure that corrects foot positioning and reduces joint stress while minimizing added complexity through straightforward attachment methods

Function Achieved in This Case
The board allows for comfortable standing with even tension reduction, enabling effective muscle strengthening, balance training, and stretching, while being versatile for different exercises and user weights, improving overall health and work efficiency.
Implementation Method 1
the body is rigid in the direction of its radius of curvature, supporting at least the weight of the user
Implementation Method 2
flexible in the direction transverse to the radius of curvature so that the multi-functional curved board can be bent in a direction transverse to the radius of curvature
Implementation Method 3
the counter-curve means are curved outwards from the opposite surface of the body
