Integrated Screw-Nut Connector for Easier Terminal Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors require separate management and handling of screw members, leading to low assemblability due to the need for additional components and complex assembly processes.
Innovation Solution
The connector integrates a screw member with one terminal and a rotatable nut with the other terminal, allowing for simplified management and handling by reducing the number of components and improving assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate screw member is used to electrically connect the bus bar and motor terminal, then the electrical connection is achieved, but the assemblability deteriorates due to separate management and handling requirements
Solution Approach 1:
The screw member is integrated with the bus bar to form a single component, eliminating the need for separate handling and assembly of the screw member. The bus bar now includes a built-in screw portion that directly engages with the motor terminal, combining the electrical conductor and fastening function into one element.
Solution Approach 2:
The bus bar is designed to serve multiple functions: it acts as both the electrical conductor and the fastening mechanism. The screw member integrated with the bus bar provides both electrical connection and mechanical fastening capabilities, reducing the total number of components needed.
2Reliability
If a separate screw member is fastened to the bus bar and motor terminal, then the electrical connection is established, but the number of components increases leading to complex management and handling
Solution Approach 1:
The screw member and bus bar are merged into a single integrated component. The bus bar includes a built-in screw portion that eliminates the need for a separate screw member, thereby reducing the total component count and simplifying inventory management and assembly procedures.
Solution Approach 2:
The integrated bus bar structure performs multiple functions simultaneously: electrical conduction, mechanical support, and fastening. This multi-functionality reduces the number of specialized components needed, simplifying the overall connector design.
