Fuse Holder Base Tilting Retaining Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse holder designs require operators to handle hot fuses during replacement, increasing the risk of burns and incorporating numerous parts that raise manufacturing costs and error probabilities, while also being cumbersome in confined spaces.
Innovation Solution
A fuse holder base with a tilting fuse retaining device that can be operated from the outside, using elastic means to transition between locking and release positions, minimizing external auxiliary parts and allowing safe, intuitive fuse extraction without direct contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking means are mounted in the inner portion of the fuse holder, then the fuse can be securely locked, but the operator must directly handle hot fuses during replacement, increasing burn risk
Solution Approach 1:
A transparent protective sheet is introduced as an intermediary between the operator and the hot fuse. This sheet allows the operator to manipulate the fuse through the sheet without direct contact, eliminating burn risk while maintaining secure locking through the integrated locking means on the sheet.
2Reliability
If multiple auxiliary parts such as springs and tilting parts are used for locking and releasing, then the fuse can be securely retained, but the manufacturing cost increases and the probability of malfunctions increases
Solution Approach 1:
Multiple functions (locking, retaining, and releasing) are merged into a single integrated protective sheet structure. The locking means are directly formed on the sheet itself rather than being separate auxiliary parts, reducing the number of components while maintaining secure fuse retention.
Solution Approach 2:
The locking mechanism utilizes the elastic deformation parameter of the flexible protective sheet. By changing the sheet from a rigid structure to a flexible one, the locking function is achieved through elastic deflection rather than mechanical springs, simplifying the overall device structure.
3Ease of operation
If the locking device is operated from the side, then the fuse can be released, but sufficient side space is required which is not available in confined cabinet spaces
Solution Approach 1:
The operation direction is changed from side access to front access. The transparent protective sheet extends to the front of the fuse holder, allowing the operator to manipulate the fuse through the front surface of the sheet, eliminating the need for side space and enabling operation in confined cabinet environments.

Function Achieved in This Case
Enables safe, comfortable, and efficient fuse replacement without contacting hot fuses, reduces manufacturing costs by integrating locking mechanisms into a single molded piece, and facilitates operation in tight spaces with front-accessible design.
Implementation Method 1
the fuse holder cover and/or fuse retaining device comprise elastic means, preferably a pair of facing elastic strips, for pushing the retaining device from the release position to the locking position
