Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grounding devices for vehicle batteries are costly and time-consuming to produce due to the need for separate processing steps and multi-part designs, leading to transition resistance issues and varying electric conductance values.
Innovation Solution
A grounding device with a contact section formed by folding over the material of the grounding device itself, eliminating the need for separate contact pins and allowing for a single-piece, integrally produced component with improved conductance and reduced production costs, using sheet metal like copper alloys for enhanced conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate contact pin is pressed into the grounding device to ensure contact connection, then the contact connection is established, but the production becomes expensive, time-consuming, and complex
Solution Approach 1:
The contact pin and grounding device are merged into a single integral component. The contact pin is formed as an extension of the grounding device body, eliminating the need for separate pressing operations and reducing production complexity while maintaining reliable contact connection.
Solution Approach 2:
The grounding device is designed to perform multiple functions: it provides grounding connection, houses the contact pin as an integrated feature, and enables contact with external power sources. This multi-functionality reduces the need for separate components and processing steps.
2Ease of manufacture
If a separate processing step is required for pressing in the contact pin, then the contact section is formed, but production costs and time increase
Solution Approach 1:
The contact pin formation is merged with the grounding device manufacturing process. Both components are produced in a single casting or forming operation, eliminating separate pressing steps and significantly improving production efficiency while reducing costs.
3Adaptability or versatility
If a multi-part design is used for the grounding device, then the contact pin can be separately installed, but additional alignment and processing steps are required
Solution Approach 1:
The contact pin and grounding device are merged into a single integral component, eliminating the need for separate installation and alignment steps. The contact pin is formed as a built-in feature during the grounding device manufacturing process, simplifying both production and assembly operations.
