Modular Fuse Unit with Detachable Auxiliary Bus Bar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fuse units require a new mold to accommodate increased circuits due to changes in vehicular conditions, making them inflexible and costly to adapt.
Innovation Solution
A modular design incorporating an auxiliary fuse unit with a detachable auxiliary bus bar and insulation protector that can be fitted to the existing unit body without the need for a new mold, allowing for the addition of new circuits by fastening and fitting the auxiliary power supply connector with the unit body's power supply connector and utilizing protrusions for heat release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fuse unit design is used, then the structure is simple and mold preparation is easy, but the adaptability to accommodate increased circuits is poor
Solution Approach 1:
The fuse unit is divided into a main body and a detachable auxiliary fuse unit. The auxiliary fuse unit can be independently attached to expand circuit capacity without redesigning the entire fuse unit structure. This segmentation allows flexible adaptation to increased circuits while keeping the base design simple.
Solution Approach 2:
The auxiliary fuse unit is designed to be detachably attachable to the main body, allowing the fuse unit's circuit capacity to dynamically adapt to changing vehicular conditions. This dynamic configuration enables the system to scale from a basic to an expanded state as needed.
2Adaptability or versatility
If a new mold is prepared to accommodate increased circuits, then the adaptability improves, but the manufacturing cost and complexity increase
Solution Approach 1:
By segmenting the fuse unit into a main body and a separate auxiliary fuse unit, the invention avoids the need for a completely new mold when circuits need to be expanded. The auxiliary unit can be manufactured separately and attached to the existing main body, significantly reducing manufacturing costs and complexity compared to creating an entirely new mold.
Solution Approach 2:
The auxiliary fuse unit is designed with universal attachment features that allow it to be integrated with the main body through standardized fitting portions. This multi-functionality enables the same auxiliary unit to be attached to various main bodies without requiring custom manufacturing, improving ease of manufacture while maintaining adaptability.
3Ease of repair
If the auxiliary fuse unit is detachably installed, then the adaptability and ease of repair improve, but the device complexity increases
Solution Approach 1:
The detachable design segments the fuse unit into replaceable modules. When repair is needed, only the auxiliary fuse unit needs to be detached and replaced, not the entire fuse unit. This modular segmentation dramatically improves ease of repair while adding minimal complexity through the attachment mechanism.
Solution Approach 2:
The dynamic detachable connection allows the auxiliary fuse unit to be easily attached and detached as needed for repair or replacement. This dynamic design simplifies maintenance operations compared to permanent fixed connections, requiring only simple mechanical attachment and detachment actions.
