Modular Electrical Outlet Assembly for Safe Frame Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical outlets with movable covers face issues in aesthetics, ease of disassembly, and safety, particularly for inexperienced users, due to complex disassembly processes and potential electrical hazards.
Innovation Solution
An electrical outlet design featuring a subassembly with a cylindrical casing, snap-fitting means, and an insulating covering, allowing easy and safe exchange of aesthetic frames and components, with a shutter mechanism for dust protection and robust construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet uses a hermetic fixing method for the casing to the switch box, then electrical safety is improved, but ease of disassembly deteriorates
Solution Approach 1:
The outlet is divided into separate modules: a fixed switch box and a removable subassembly containing the casing, aesthetic frame, and electrical components. This segmentation allows the switch box to remain permanently fixed for safety while the other components can be easily removed for maintenance or aesthetic changes.
2Ease of operation
If the outlet provides direct access to connection terminals, then ease of assembly is improved, but safety deteriorates due to electrical hazards
Solution Approach 1:
The subassembly is pre-assembled with all electrical connections made beforehand in a safe environment. The complete subassembly is then connected to the switch box through isolated connection points, allowing easy installation while preventing direct exposure to electrical terminals during the assembly process.
3Reliability
If the outlet uses a complex fixing mechanism for the casing, then reliability is improved, but device complexity increases
Solution Approach 1:
The fixing system is segmented into two distinct mechanisms: simple snap-fitting means for attaching the subassembly to the switch box, and separate connection means for joining the switch box to the framework. This segmentation reduces overall complexity while maintaining reliability through specialized simple fixing methods for each interface.
