Vehicle Jump Starter Housing Structure for Stable Terminal Mounting
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 its specific mounting function, improving overall reliability without excessive complexity.
Solution Approach 2:
The output terminal is nested within the second accommodating space of the first mounting part, which itself is housed in the first accommodating space of the shell. This nested arrangement ensures secure positioning of critical components while maintaining a compact overall structure, resolving the contradiction between reliability and complexity.
2Duration of action of stationary object
If the output terminal is not securely housed, then the ease of manufacture is improved, but the lifespan of the emergency starting power supply deteriorates
Solution Approach 1:
The first mounting part is pre-formed with the second accommodating space and positioning protrusions during the molding process. This preliminary action ensures that the output terminal will be securely housed upon assembly, extending the lifespan of the device without requiring complex post-assembly operations or specialized manufacturing equipment.
Solution Approach 2:
The first mounting part acts as an intermediary component between the shell and the output terminal. It provides the second accommodating space that securely houses the output terminal, while also featuring coupling parts that facilitate easy assembly and disassembly. This intermediary structure resolves the contradiction between lifespan and ease of manufacture.
3Reliability
If the circuit board and power source are not firmly positioned, then the device complexity is reduced, but the reliability of electrical connections deteriorates
Solution Approach 1:
The shell is designed with localized positioning features (protrusions and recesses) at specific locations where the power source and circuit board need to be firmly positioned. This local quality approach ensures reliable electrical connections at critical points without requiring a complex overall positioning structure, thus resolving the contradiction between connection reliability and structural complexity.
