Terminal Block Shield Bracket Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal block structures require multiple components to hold shield materials, leading to inefficiencies and spring back issues when a single folded bracket is used, resulting in loose caulking and ineffective material retention.
Innovation Solution
A terminal block design featuring two shield brackets with a U-shaped folding portion and notch holes along the fold line, allowing the shield material to be securely sandwiched and held by a single member, reducing component count and preventing spring back.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shield bracket is folded to hold the shield material, then the number of components is reduced, but spring back occurs causing loose caulking and ineffective retention
Solution Approach 1:
The folding portion is divided into multiple segments by forming notch holes along the fold line, creating a multi-segmented structure that reduces spring back while maintaining component count reduction
Solution Approach 2:
The physical structure of the folding portion is changed by adding notch holes, which modify the mechanical properties to reduce spring back effect while maintaining the single-component design
2Reliability
If two members are used to sandwich and hold the shield material, then reliable retention is achieved, but the number of components increases reducing working efficiency
Solution Approach 1:
Multiple functions (holding, sandwiching, and securing the shield material) are merged into a single shield bracket component, eliminating the need for separate members while maintaining reliable retention
Solution Approach 2:
The single bracket's folding portion is segmented via notch holes to provide effective retention without requiring multiple separate components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively reduces the number of components needed to hold the shield material, ensuring secure retention and preventing loosening, thereby enhancing working efficiency and assembly ease.
Implementation Method 1
spring back occurs after bending, so that the caulking is loosened
