Adjustable Seat Mechanism for Universal Training Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoulder wing training apparatuses are not user-friendly for both healthy individuals and wheelchair users, as they require manual adjustments and do not allow for optimal positioning of the seat during exercises, leading to inefficient training and cumbersome repositioning.
Innovation Solution
A training apparatus with a seat connecting unit, moving mechanism, and fixing mechanism that includes a horizontal rotating body, vertical rotating body, and spring-type pin for easy adjustment and secure positioning, allowing both healthy individuals and wheelchair users to perform exercises at the optimal position without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the seat is fixed at an optimum position for healthy persons, then healthy persons can perform stretching exercise at the optimum position, but wheelchair users cannot use the apparatus without physical removal of the seat
Solution Approach 1:
The seat position is changed from fixed to movable through the provision of a moving mechanism with locking and unlocking capabilities. The seat can be dynamically adjusted between a locked optimum position for healthy persons and an unlocked movable state for wheelchair users, allowing the apparatus to adapt to different user needs without physical removal of components.
2Adaptability or versatility
If the seat is made movable to allow wheelchair users to use the apparatus, then both healthy persons and wheelchair users can train, but the seat may not be accurately positioned for healthy persons
Solution Approach 1:
The manual positioning method is replaced with an automatic positioning mechanism that uses a motor to move the seat along a rail to a predetermined optimum position. This mechanical substitution ensures accurate and consistent positioning for healthy persons while maintaining the ability to move the seat for wheelchair users, eliminating the positioning accuracy problem associated with manual movement.
3Adaptability or versatility
If the seat is manually moved for wheelchair users, then wheelchair users can use the apparatus, but repositioning the seat after use is extremely troublesome
Solution Approach 1:
The system provides self-service functionality through automatic detection of wheelchair presence and automatic seat positioning. When a wheelchair is detected, the seat automatically moves to an accessible position without manual intervention. After use, the seat automatically returns to its optimum position, eliminating the troublesome manual repositioning process and reducing the time loss associated with seat repositioning.
4Device complexity
If the seat connecting unit uses a fixed connection, then the structure is simple, but the seat cannot be adjusted for different users
Solution Approach 1:
The seat connecting unit is transformed from a fixed rigid connection to a dynamic adjustable connection through the integration of a moving mechanism with locking and unlocking capabilities. This allows the seat to be fixed in position for healthy persons while being movable for wheelchair users, achieving adaptability without significantly increasing structural complexity.
