Vehicle Jump Starter Housing Layout 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 for the power source and circuit board, and a first mounting part with a second accommodating space for the output terminal, enhancing stability and reliability through secure mounting configurations.
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 while collectively providing stable mounting 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 provides multiple levels of containment and stability while maintaining a compact overall structure.
2Reliability
If the power source, circuit board, and output terminal are securely mounted with multiple mounting parts and accommodating spaces, then the mounting stability and reliability improve, but the device complexity increases
Solution Approach 1:
The first mounting part combines multiple functions: it provides the second accommodating space for the output terminal, includes positioning features (protrusions and recesses) for precise alignment, and integrates cable mounting openings. This merging of functions into a single component reduces the number of separate parts needed while maintaining mounting stability.
Solution Approach 2:
The positioning protrusions and recesses are pre-formed during manufacturing, establishing precise alignment between components before final assembly. The cable mounting openings are also pre-positioned in the first mounting part, allowing cables to be routed and secured without additional complex fixtures.
3Reliability
If the output terminal is housed in a separate second accommodating space within the first mounting part, then the mounting stability improves, but the device complexity increases
Solution Approach 1:
The mounting structure utilizes three-dimensional spatial arrangement by creating a nested hierarchy: the first accommodating space in the shell contains the first mounting part, which in turn contains the second accommodating space for the output terminal. This multi-level spatial organization provides stable mounting while maintaining compact dimensions.
