Regulating Member Single-Handed Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing regulating members for gymnastic machines require the use of both hands to adjust and release the operating unit, making it cumbersome for operators performing multiple tasks simultaneously, especially in multi-station machines where users may hinder each other, thereby limiting efficient space utilization.
Innovation Solution
A regulating member with a blocking device and handle system that allows the operating unit to be slidably coupled to an elongated member, enabling single-handed adjustment and release through a tiltable switching mechanism and guiding device, facilitating easy positioning and movement along the upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional blocking device with pin and hole system is used, then the operating unit can be securely fixed in position, but both hands are required to operate it making it cumbersome
Solution Approach 1:
A switching member acts as an intermediary mechanism between the user's hand and the blocking pin. This switching member can be actuated by a single hand to simultaneously control the pin's engagement and disengagement from the upright, eliminating the need for two hands while maintaining secure fixing when engaged.
Solution Approach 2:
The switching member combines multiple functions into a single component: it controls the blocking pin's engagement, provides a user-friendly interface, and enables single-handed operation. By merging these functions, the system achieves both reliable fixing and ease of operation.
2Manufacturing precision
If both hands are required to adjust and release the operating unit, then positioning can be controlled precisely, but space utilization in multi-station machines is limited
Solution Approach 1:
The switching member serves as an intermediary that translates single-handed input into precise control of the blocking pin's position. This allows users to adjust and release the operating unit with one hand, freeing the other hand for different tasks and improving space utilization in multi-station environments.
3Device complexity
If a simple pin and hole system is used, then the device complexity is low, but the operation requires two hands reducing productivity
Solution Approach 1:
The switching member merges the functions of position selection and pin control into a single mechanism. This allows faster adjustment operations since only one hand needs to operate the switching member rather than manually manipulating the pin and hole system, thereby increasing productivity without significantly increasing device complexity.
