Vehicle Jump Starter Assembly for Stable Output 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 design 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 by secure mounting of components.
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 shell is divided into a first accommodating space for the power source and circuit board, and a second accommodating space for the output terminal. The first mounting part is segmented with specific positioning structures. This segmentation allows each component to be mounted in its dedicated space with appropriate fixing structures, improving mounting stability without significantly increasing overall device complexity.
Solution Approach 2:
The first mounting part acts as an intermediary structure between the shell and the output terminal. It includes positioning protrusions and limiting structures that mediate the connection, providing stable mounting for the output terminal while integrating seamlessly with the shell structure.
2Reliability
If the components are securely mounted with multiple positioning structures, then the reliability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The mounting structures are segmented into distinct positioning protrusions and receiving grooves on different components. The first mounting part has positioning protrusions that engage with corresponding grooves on the circuit board, while the shell has limiting structures for the output terminal. This segmentation allows for modular assembly, improving reliability while maintaining ease of manufacture through straightforward snap-fit or screw connections.
3Reliability
If the output terminal is partially housed in the second accommodating space, then the mounting stability is improved, but the device complexity increases
Solution Approach 1:
The output terminal is partially housed within the second accommodating space of the first mounting part, which itself is integrated into the shell structure. This nested arrangement allows the output terminal to be securely positioned while utilizing the existing shell structure, improving stability without adding significant structural complexity.
Solution Approach 2:
The first mounting part combines multiple functions: it provides the second accommodating space for the output terminal, includes positioning structures for secure mounting, and integrates with the shell's first accommodating space. This merging of functions into a single component improves output terminal stability while avoiding the need for separate mounting brackets or additional structural elements.
