Card Adaptor Integrated Short-Circuiting and Distortion Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional card adaptors increase manufacturing costs and mounting complexity by requiring separate conducting members for short-circuiting external connecting parts, and are prone to damage from card distortion during mounting.
Innovation Solution
A card adaptor with integrated short-circuit parts at the edges of external connecting parts, formed through upward or downward bending, which can be manufactured simultaneously with the connecting parts, allowing for short-circuiting without additional components and absorbing variations in length, along with a card guide to redirect distortion forces away from the case's engaging parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate conducting members are provided to short-circuit specific external connecting parts, then the short-circuiting function is achieved, but the number of parts increases and mounting work complexity increases
Solution Approach 1:
The patent merges the short-circuiting function with the external connecting parts themselves by forming conducting members integrally with these parts. Specifically, the ground external connecting parts have conducting members that extend and connect to signal external connecting parts, eliminating the need for separate short-circuiting components. This integration maintains the required short-circuiting reliability while reducing part count and mounting complexity.
Solution Approach 2:
The external connecting parts are designed to serve multiple functions: they provide signal connection and simultaneously serve as the short-circuiting path through their integrated conducting members. The ground external connecting parts function both as signal interfaces and as the means to short-circuit specific signal external connecting parts, thereby achieving multi-functionality that resolves the contradiction between reliability and device complexity.
2Manufacturing precision
If the card adaptor structure is rigid to maintain precision, then manufacturing precision is improved, but the structure becomes vulnerable to damage from card distortion forces
Solution Approach 1:
The patent introduces a card guide that is capable of moving relative to the case along the card insertion direction. This dynamic structure allows the card guide to absorb distortion forces generated during card mounting by deforming or moving, rather than transmitting these forces to the rigid engaging parts. The dynamic card guide maintains manufacturing precision of the engaging parts while providing flexibility to resist damage from card distortion.
3Strength
If the card guide is made movable to absorb distortion forces, then durability is improved, but the structure complexity increases
Solution Approach 1:
The patent segments the card adaptor structure into distinct functional components: a fixed case with engaging parts and a movable card guide. This segmentation allows the card guide to be designed as a separate, simple movable element that absorbs distortion forces through its movement capability, while the main case structure remains simple and rigid. The segmentation enables durability improvement without significantly increasing overall structure complexity.
