Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conductor coatings are prone to damage during assembly and conveyance due to friction with the core in existing technologies, leading to potential electrical failures.
Innovation Solution
A conductor unit design featuring a columnar or plate-like core with a spiral busbar configuration, where the core is accommodated within a housing member and held by an adhesive member, preventing relative movement and thus minimizing friction and coating damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core is fixed to the circuit device body using a fixing device, then the core is securely positioned, but the conductor coating may be damaged due to friction during assembly and conveyance
Solution Approach 1:
The core is divided into a first core constituent portion and a second core constituent portion, allowing the conductor to be inserted through a hollow portion before the portions are joined together, reducing friction and coating damage during assembly
Solution Approach 2:
The conductor is inserted into the hollow portion of the first core constituent portion before the second core constituent portion is joined to it, allowing the conductor to be positioned securely before final fixation, minimizing friction and coating damage
2Ease of operation
If the conductor is movable relative to the core, then assembly flexibility is improved, but friction between the conductor and core damages the coating during conveyance and assembly
Solution Approach 1:
The core is segmented into two portions that are joined after conductor insertion, providing initial flexibility during assembly while ensuring final fixed positioning to prevent coating damage during conveyance
Solution Approach 2:
The conductor is preliminarily positioned in the hollow portion before the core portions are joined, allowing easy insertion while ensuring subsequent fixed positioning to prevent friction-related coating damage
