Electric Wire Connection Structure for Precise Core Wire Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wire connection structures face difficulties in maintaining consistent distances between core wire exposed portions, which is crucial for precise connections, especially in medical devices where size and precision are critical.
Innovation Solution
An electric wire connection structure comprising covered electric wires with exposed core wire portions arranged in parallel, fixed by a core wire fixing member, and connected to electrodes using a conductive bonding material, with a sealing material to prevent moisture ingress, and a method that involves preparing, fixing, and connecting these wires to ensure precise alignment and secure bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If core wire exposed portions are arranged in parallel without a fixing member, then the structure is simpler, but the distances between core wire exposed portions cannot be maintained
Solution Approach 1:
A core wire fixing member is introduced as an intermediary component to maintain the distances between core wire exposed portions. This fixing member serves as a mediator that holds the core wires at precise intervals, resolving the contradiction by adding a specific structural element that enables distance maintenance without requiring complex external fixtures or assembly processes.
2Manufacturing precision
If core wire exposed portions are fixed to each other, then distances are easily maintained, but the manufacturing process becomes more complex
Solution Approach 1:
The core wire fixing member is designed to pre-establish the correct spacing between core wire exposed portions before the connection to electrodes. By performing the distance maintenance action in advance during the wire arrangement stage, the subsequent connection process becomes simpler and more straightforward, resolving the contradiction between precision and manufacturing ease.
3Reliability
If multiple components are used to fix and seal the connection, then reliability is improved, but the device size increases
Solution Approach 1:
The core wire fixing member is designed to perform multiple functions simultaneously: it fixes the core wires to each other, maintains precise distances, and provides a mounting surface for the sealing member. By merging these functions into a single integrated component, the design achieves high connection reliability without significantly increasing device size, as the fixing and sealing functions are combined rather than separated into multiple discrete components.
