Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal fitting connection structure requires a large number of components, including a male terminal and multiple female terminals, which increases complexity and cost.
Innovation Solution
A terminal fitting connection structure where terminal fittings with a square tubular shape and protrusions are arranged side by side, with each fitting having a connecting portion and an opening that allows adjacent protrusions to connect, eliminating the need for additional conductive members by directly connecting through these protrusions and openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a male terminal and multiple female terminals are used to connect terminal fittings, then electrical connectivity between terminal fittings is achieved, but the number of components increases and structural complexity increases
Solution Approach 1:
The invention merges the male terminal and female terminals into a single integrated terminal fitting structure. Each terminal fitting includes both male and female connection portions, allowing adjacent terminal fittings to connect directly to each other without requiring separate male and female terminals. This integration eliminates the need for additional conductive members and reduces the total number of components while maintaining electrical connectivity functionality.
2Reliability
If a male terminal and multiple female terminals are used to connect terminal fittings, then electrical connectivity between terminal fittings is achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The invention combines multiple terminal components into a single molded terminal fitting, integrating the terminal body, connection portions, and insulating structures into one manufacturable unit. This reduces the number of separate parts that need to be manufactured, assembled, and quality-checked, thereby simplifying the manufacturing process and reducing production costs while ensuring reliable electrical connectivity.
3Reliability
If additional conductive members are used to connect terminal fittings, then electrical connectivity is ensured, but the number of components and assembly complexity increase
Solution Approach 1:
The terminal fitting is designed with integrated male and female connection portions that enable direct connection between adjacent terminal fittings without requiring additional conductive members or complex assembly steps. The structure itself provides the necessary electrical connectivity pathways, allowing the terminal fittings to serve their own connection function and eliminating the need for separate assembly operations involving additional components.
