Folded Switch Guard Insulation for Stable Meter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical switch configurations lack effective insulation, which can lead to physical contact and momentary switching issues, potentially causing inaccurate power measurement and safety hazards during testing and operation.
Innovation Solution
A switch cover formed from a folded sheet of electrically insulating material with pre-formed fold lines, including an extension wall that can be placed between jaws of the switch, providing insulation and securing the cover to the switch components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If switch components are left exposed without insulation, then the device complexity is reduced and ease of manufacture is improved, but safety hazards increase and momentary switching issues occur due to physical contact
Solution Approach 1:
The patent applies this principle by using a thin sheet of electrically insulating material that is folded to create the switch guard. This thin film approach provides necessary insulation without adding significant structural complexity, preventing physical contact between switch components while maintaining ease of manufacture through simple folding operations along pre-formed fold lines.
Solution Approach 2:
The patent applies this principle by dividing the insulating material into specific sections with fold lines that create distinct walls and compartments. The fold lines segment the material to form vertical walls that separate switch components, providing targeted insulation where needed while keeping the overall structure simple and manufacturable.
2Object-affected harmful factors
If a switch guard is added to provide insulation, then safety is improved and physical contact is prevented, but the device complexity increases and manufacturing becomes more difficult
Solution Approach 1:
The patent applies this principle by incorporating pre-formed fold lines into the insulating material before assembly. These pre-formed fold lines allow the material to be easily folded into the required guard configuration during assembly, significantly reducing manufacturing difficulty while still providing complete insulation and safety protection for switch components.
Solution Approach 2:
The patent applies this principle by designing the insulating material with self-forming features where the folded structure creates its own support and positioning. The fold lines enable the material to form stable vertical walls and compartments that self-align with switch components, reducing the need for additional fastening mechanisms or complex assembly procedures.
3Reliability
If insulation material is placed between switch jaws, then momentary switching issues are prevented, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent applies this principle by concentrating the insulating material specifically between the switch jaws where physical contact and momentary switching issues occur. The fold lines create localized insulation walls at critical interfaces rather than enclosing the entire switch assembly, providing targeted protection against harmful contact while minimizing overall device complexity and assembly difficulty.

AI summary
A method of insulating an electrical switch includes forming a switch cover having a front wall, a first side wall, a second side wall, a top wall, and an open bottom opposite the top wall by folding a sheet of electrically insulating material. The method includes placing the switch cover over a component of the electrical switch, the component extending into the switch cover through the open bottom.
