Vehicle Jump Starter Terminal Mounting for Higher Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency starting power supplies for vehicles suffer from mounting instability and poor reliability of the power source, circuit board, and output terminals, leading to a relatively low lifespan.
Innovation Solution
The emergency starting power supply includes a shell with a first accommodating space and a first mounting part, where the power source and circuit board are housed and electrically connected to the output terminal. The output terminal is securely mounted in a second accommodating space of the first mounting part, enhancing stability and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power source, circuit board, and output terminal are loosely mounted in the shell, then the device complexity is reduced, but the mounting stability and reliability deteriorate
Solution Approach 1:
The mounting structure is segmented into multiple independent components: the shell with first accommodating space, the first mounting part with second accommodating space, and separate positioning features (protrusions and recesses). This segmentation allows each component to be optimized independently for stability while maintaining overall simplicity.
Solution Approach 2:
The first mounting part acts as an intermediary component between the shell and the output terminal. It provides a dedicated mounting interface with the second accommodating space, mediating the connection and enhancing stability without requiring direct complex integration between the shell and terminal.
2Reliability
If the output terminal is not securely housed, then the ease of manufacture is improved, but the reliability and lifespan of the device deteriorate
Solution Approach 1:
The first mounting part is pre-configured with the second accommodating space and positioning protrusions during manufacturing. This preliminary action ensures that the output terminal will be securely housed upon assembly, improving reliability without adding significant manufacturing complexity.
Solution Approach 2:
The mounting structure is designed to be self-aligning and self-securing through the protrusion-recess interface. The output terminal automatically positions itself within the second accommodating space, eliminating the need for additional fastening operations or complex alignment procedures during assembly.
3Stability of the object's composition
If the circuit board is not positioned and limited, then the device complexity is reduced, but the mounting stability deteriorates
Solution Approach 1:
The first mounting part provides localized positioning features (protrusions) specifically at the circuit board mounting locations. This local quality approach ensures stability only where needed, rather than requiring comprehensive complex mounting structures throughout the entire device.
