Operation Unit Support Structure for Multi-Direction Movement Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation apparatuses face challenges in restricting extra movement of the operation unit without adding complex stopper mechanisms, especially when installed outside the instrument panel, which complicates the restriction of movement in multiple directions.
Innovation Solution
The operation apparatus incorporates a support member with a coupling support portion that includes an elastic deformation portion, allowing the operation unit to be fixed and restricting its movement by a restriction portion that comes into contact when the elastic deformation occurs, thereby eliminating the need for a separate stopper mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a separate stopper mechanism is added to restrict the operation unit's movement in multiple directions, then the movement restriction capability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the stopper function with the support member by integrating a stopper protrusion directly into the support member structure. This eliminates the need for a separate stopper mechanism, thereby restricting the operation unit's movement in multiple directions while maintaining simple device structure. The support member now performs both support and movement restriction functions simultaneously.
2Stability of the object's composition
If a separate stopper mechanism is added to restrict the operation unit's movement, then the movement restriction capability is improved, but the number of components increases
Solution Approach 1:
The patent combines the stopper function with the support member by integrating a stopper protrusion directly into the support member structure. This eliminates the need for a separate stopper mechanism, thereby restricting the operation unit's movement in multiple directions while maintaining simple device structure. The support member now performs both support and movement restriction functions simultaneously.
3Stability of the object's composition
If a separate stopper mechanism is added to restrict the operation unit's movement, then the movement restriction capability is improved, but the assembly steps increase
Solution Approach 1:
The patent merges the stopper function with the support member by integrating a stopper protrusion directly into the support member structure. This eliminates the need for a separate stopper mechanism, thereby restricting the operation unit's movement in multiple directions while maintaining simple device structure.

AI summary
A unit chassis of an operation unit is fixed by a fixing screw to a coupling support portion provided at a support member. A front contact portion is formed at a fixing piece provided at the coupling support portion, and a front restriction portion formed at a right plate portion of the support member and the front contact portion face each other to be spaced apart by a distance in the front-rear direction (Z1-Z2 direction). When the operation unit is pulled toward the near side (Z1 direction), the front contact portion comes into contact with the front restriction portion and restricts a movement of the operation unit.
