Vehicle Jump Starter Terminal Mounting for Stable Internal Assembly
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 simply placed in the shell without dedicated mounting structures, then the device complexity is reduced, but the mounting stability and reliability deteriorate
Solution Approach 1:
The shell is divided into functional zones: a first accommodating space for the power source and circuit board, and a second accommodating space within the first mounting part for the output terminal. This segmentation allows each component to be securely positioned in its designated space, improving mounting stability without requiring complex external mounting structures.
Solution Approach 2:
The second accommodating space is nested within the first mounting part, which itself is part of the shell structure. This nested arrangement allows the output terminal to be securely housed within the mounting part, while the mounting part remains integrated into the overall shell structure, maintaining reliability without adding external complexity.
2Reliability
If dedicated mounting parts and accommodating spaces are added for each component, then the mounting stability and reliability are improved, but the device complexity increases
Solution Approach 1:
The first mounting part serves multiple functions: it provides the second accommodating space for the output terminal, acts as a structural support element, and integrates into the shell's first accommodating space. By merging these functions into a single component, the structure achieves high reliability without proportional increases in complexity.
Solution Approach 2:
The first mounting part is designed as a multi-functional component that simultaneously provides mechanical support, houses the output terminal in its second accommodating space, and integrates with the shell's first accommodating space. This multi-functionality reduces the need for separate dedicated mounting structures for each component.
3Duration of action of stationary object
If the output terminal is securely housed in the second accommodating space of the first mounting part, then the lifespan of the emergency starting power supply is extended, but the ease of manufacture decreases
Solution Approach 1:
The first mounting part is pre-formed with the second accommodating space during shell manufacturing. This preliminary preparation of the mounting structure allows the output terminal to be securely installed during final assembly, extending lifespan through proper mounting while maintaining ease of manufacture by avoiding post-assembly modifications.

AI summary
An emergency starting power supply for vehicles includes a shell, a power source, a circuit board, and an output terminal. The shell is provided with a first accommodating space and a first mounting part. The power source and circuit board are housed in the first accommodating space. The power source is electrically connected to the circuit board and the output terminal, respectively. The first mounting part is provided with a second accommodating space, and at least a portion of the output terminal is housed in the second accommodating space. The output terminal is configured to output a current for starting an engine of the vehicle. The output terminal is arranged between the first mounting part and the circuit board.
