Substrate Fixing Structure With Spacer And Pressing Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing substrate fixing methods, such as using screws or synthesized resin, often result in twisting stress on inter-substrate connectors, leading to potential damage and backlash, especially in high-temperature environments, and are cumbersome to assemble.
Innovation Solution
A substrate fixing structure that includes a spacer member maintaining a predetermined distance between substrates, a pressing portion to suppress twisting forces, and a locking member fixed in the first substrate, which reduces loads on inter-substrate connectors and rectifies gaps caused by creep, eliminating the need for screws and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to fix substrates, then the substrates can be securely fixed, but twisting stress is applied to inter-substrate connectors causing potential damage
Solution Approach 1:
The fixing function is segmented into multiple independent elements: clamp members that apply pressing force, positioning members that maintain spatial relationships, and locking members that prevent displacement. This segmentation eliminates the need for screws that generate twisting moments, thereby protecting inter-substrate connectors while achieving secure fixation.
2Ease of manufacture
If synthesized resin is used to fix substrates, then assembly is simplified, but creep occurs in high-temperature environments causing backlash
Solution Approach 1:
The fixing structure employs a composite approach combining clamp members (for pressing force), positioning members (for spatial positioning), and locking members (for stability). This composite structure replaces single-material resin solutions, providing both ease of assembly and resistance to high-temperature creep while maintaining electrical connection reliability.
3Strength
If multiple small parts are used for every screw hole, then fixing can be achieved, but assembling procedures become troublesome
Solution Approach 1:
Multiple fixing functions are merged into integrated components. The clamp members combine pressing and positioning functions, while the locking members integrate multiple stabilization roles. This merging reduces the number of discrete small parts needed per screw hole location, significantly simplifying assembly procedures while maintaining fixing strength.
