Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting shield covers on circuit substrates face issues with unreliable fastening and ground connection, often requiring screws or conductive tape, leading to poor assembly workability and increased component count.
Innovation Solution
A shield cover with an elastic and deformable convex insertion part that contacts the circuit substrate's ground pattern, establishing reliable fastening and ground connection without the need for additional screws, using the convex part as a fulcrum for contact with both the substrate and the shield cover's fastening part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten the shield cover, then reliable fastening and ground connection are achieved, but the number of components increases and assembly workability deteriorates
Solution Approach 1:
The patent combines the fastening function and ground connection function into a single insertion part structure. The insertion part simultaneously engages with the fastening part to provide mechanical fastening and contacts the ground pattern to establish electrical connection, eliminating the need for separate screws and conductive tape
Solution Approach 2:
The insertion part is designed to perform multiple functions: it acts as both a mechanical fastening element (engaging with the fastening part) and an electrical connection element (contacting the ground pattern). This multi-functional design replaces multiple specialized components with a single universal element
2Ease of operation
If conventional insertion structure is used without elastic convex part, then assembly is simple, but fastening reliability and ground connection stability are insufficient
Solution Approach 1:
The patent introduces elastic material properties and a convex shape to the insertion part, changing its physical parameters. The elasticity allows the insertion part to deform and apply continuous contact pressure, while the convex shape provides a fulcrum point for leverage. These parameter changes enable the simple insertion structure to achieve reliable fastening and stable ground connection
3Strength
If multiple screws are used for mounting, then fastening strength is sufficient, but assembly workability and productivity deteriorate
Solution Approach 1:
The patent extracts the fastening function from the traditional screw mechanism and integrates it into the insertion part itself. The insertion part incorporates the fastening capability directly, eliminating the need for separate screw components and simplifying the assembly process while maintaining sufficient fastening strength
