Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shield connectors for vehicles face challenges in easy assembly and risk of short circuits when connecting multiple rows of terminals and wires, particularly due to the complexity of soldering and the inability to stack or accommodate housings until solder connections are completed.
Innovation Solution
A shield connector design featuring a housing with a housing extending plate that allows for easy soldering of terminals and wires before assembly, with a shield shell having first and second openings for exposing the housing extending plate, preventing short circuits and enabling easier assembly by allowing the connector to be assembled in stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If connection terminals are arranged in multiple rows to increase connectivity, then the connector can accommodate more terminals, but the risk of short circuits between rows increases and assembly becomes more complex
Solution Approach 1:
The housing is divided into multiple row-specific compartments that physically separate terminals arranged in multiple rows. Each compartment acts as an isolated chamber that prevents conductive paths from bridging between adjacent rows, thereby maintaining reliability while accommodating increased terminal quantity.
Solution Approach 2:
Non-conductive insulating materials are introduced as intermediary elements between terminal rows and within the housing structure. These insulating barriers prevent direct electrical contact between adjacent terminals in different rows, eliminating the short circuit risk while allowing dense terminal arrangement.
2Ease of operation
If soldering technique is used instead of crimp connecting to ease assembly, then connection ease is improved, but the risk of short circuits between rows increases due to solder bridging
Solution Approach 1:
The housing compartments segment the soldering workspace into isolated zones for each terminal row. This physical separation allows soldering operations to be performed on multiple rows simultaneously or in sequence without risk of solder bridging between rows, maintaining both assembly ease and electrical reliability.
Solution Approach 2:
Non-conductive insulating barriers are positioned between terminal rows to act as intermediaries that block solder flow and prevent solder bridging. These barriers enable the use of soldering technique for ease of assembly while eliminating the short circuit risk that would otherwise result from solder spreading between adjacent rows.
3Reliability
If separate housings are provided for each row to prevent short circuits, then short circuit risk is reduced, but device complexity and size increase
Solution Approach 1:
Multiple row-specific compartments are merged into a single integrated housing structure. The housing combines the functions of multiple separate housings into one unified component that provides all necessary isolation barriers and structural support, thereby maintaining short circuit prevention while reducing overall device complexity and size.
Solution Approach 2:
The integrated housing performs multiple functions simultaneously: it provides structural support for all terminal rows, creates isolated compartments for each row, incorporates insulating barriers for electrical separation, and enables standardized assembly procedures. This multi-functionality eliminates the need for separate housings while maintaining reliability.
4Reliability
If housings are joined after soldering to prevent short circuits, then short circuit risk is reduced, but work sequence is restricted and assembly becomes more complex
Solution Approach 1:
The housing with its integrated isolation barriers and compartment structures is prepared in advance before soldering operations. This preliminary preparation of the housing structure allows soldering to be performed immediately after terminal insertion without requiring subsequent housing assembly steps, thereby preventing short circuits while maximizing work sequence flexibility and productivity.
