Removable Rocker Switch Unit With Integrated Fuse Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocker switches have too many mechanical parts, leading to higher production costs, increased risk of failure, and difficulties in replacing fuses and repairing the units, which are often bulky and space-consuming.
Innovation Solution
A rocker switch unit with a simplified design featuring a single moulded housing and fewer mechanical parts, allowing easy removal and replacement of fuses or the entire unit, with concealed electrical elements and flexible connection elements for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional rocker switches with multiple mechanical parts are used, then the switching function is achieved, but the production cost increases and the reliability decreases
Solution Approach 1:
The patent combines the fuse holder and switching mechanism into a single integrated rocker switch unit. The housing encompasses both the fuse receptacle and the rocking contact assembly, eliminating the need for separate mechanical components that were previously required. This merging reduces the number of parts while maintaining the switching function and improving reliability through fewer potential failure points.
2Ease of manufacture
If the fuse is enclosed inside the switch housing, then the appearance is improved and protection is enhanced, but the ease of replacing the fuse deteriorates
Solution Approach 1:
The patent segments the rocker switch unit into a removable module that can be easily detached from the apparatus housing. The entire fuse holder assembly with the fuse pre-installed forms a replaceable unit, allowing users to simply remove and replace the entire module rather than disassembling multiple components to access the fuse. This segmentation maintains protection during normal operation while enabling easy replacement during maintenance.
3Ease of repair
If the rocker switch unit is designed to be removable, then the ease of maintenance is improved, but the connection stability may deteriorate
Solution Approach 1:
The patent extracts the entire fuse holder and switching mechanism as a complete removable unit from the apparatus housing. This extraction design allows the unit to be easily removed for maintenance or replacement while incorporating built-in connection features that ensure stable electrical and mechanical connections when installed. The unit includes integrated contacts and mounting structures that maintain stability during operation.
