Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sockets that use an operation driver to elastically deform a spring member for connecting leads often result in plastic deformation of the spring member due to erroneous operation.
Innovation Solution
A socket design featuring a position restricting protrusion on the base that comes into contact with the deformed spring member to prevent plastic deformation, along with a guide partition wall and tapered surfaces to enhance assembly precision and prevent stress concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operation driver presses and deforms the spring member to connect leads, then the connection function is achieved, but the spring member is plastically deformed due to erroneous operation
Solution Approach 1:
The position restricting protrusion is provided in advance on the base to prevent plastic deformation of the spring member. When the operation driver presses the spring member, the protrusion restricts the spring member's movement to prevent excessive deformation, thereby applying counter-action before erroneous operation can cause damage.
Solution Approach 2:
The position restricting protrusion acts as an intermediary element between the base and the spring member. It mediates the interaction by providing a physical barrier that limits the spring member's deformation range, preventing direct harmful contact between the operation driver and the spring member during erroneous operation.
2Productivity
If the position restricting protrusion is integrally molded with the base, then the number of parts and assembly time are reduced, but the assembly precision may be compromised
Solution Approach 1:
The position restricting protrusion is integrally molded with the base, merging two components into one. This combination reduces the total number of parts and eliminates assembly steps, thereby improving productivity while maintaining functional integrity through integrated design.
Solution Approach 2:
The protrusion is designed with specific local geometric features (position, shape, dimensions) that ensure precise restriction of the spring member's movement. The local quality of the protrusion's geometry compensates for the loss of assembly precision by providing built-in positioning accuracy through its integral design.
3Object-affected harmful factors
If the spring member is restricted to prevent plastic deformation, then the spring member's elastic deformation capability is limited
Solution Approach 1:
The position restricting protrusion applies preliminary anti-action by setting a physical limit on the spring member's deformation range. It prevents the spring member from exceeding its elastic limit during operation, thereby protecting against plastic deformation while allowing normal elastic deformation within the restricted range.
Solution Approach 2:
The protrusion changes the operational parameters of the spring member by defining a specific deformation range. It modifies the spring member's movement parameters (position, amplitude) to remain within the elastic deformation zone, ensuring that the spring member operates within safe parameter boundaries.
