Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal covers for electrical devices are expensive, difficult to install, and structurally complex, posing risks of shorting and electric shock due to exposed metal terminals.
Innovation Solution
Magnetic terminal covers made of insulative material with embedded magnets that magnetically attach to terminals, providing lateral shielding and easy installation without additional fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional terminal covers are used, then terminals are insulated and protected, but the covers are expensive, difficult to install, and structurally complex
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with magnetic attraction. The cover includes magnetic material that magnetically couples to the terminal, eliminating the need for complex mechanical attachment mechanisms while maintaining secure coverage and protection of the terminal.
2Reliability
If traditional terminal covers are used, then terminals are insulated and protected, but the covers are expensive and difficult to install
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, adhesives) with magnetic attraction. The cover includes magnetic material that magnetically couples to the terminal, eliminating the need for complex mechanical attachment mechanisms while maintaining secure coverage and protection of the terminal.
Solution Approach 2:
The magnetic cover attaches to the terminal automatically through magnetic attraction when brought into proximity, requiring no additional tools, fasteners, or assembly steps. The installer simply positions the cover near the terminal and the magnetic force secures it in place, making installation trivial and tool-free.
3Ease of operation
If magnetic material is embedded in the cover, then the cover attaches easily to the terminal, but the magnetic material must be exposed and adhered adhesively
Solution Approach 1:
The magnetic material is pre-adhered to the cover during the covering member formation process, such as during molding or manufacturing. This preliminary attachment of the magnetic material eliminates the need for separate adhesion steps during final assembly, simplifying the overall manufacturing process while ensuring the magnetic cover attaches easily to the terminal through magnetic attraction.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Inexpensive and easy-to-install covers effectively prevent shorting and electric shock by ensuring terminals remain insulated and inaccessible during installation, removal, or servicing.
Implementation Method 1
a magnetic attraction between the magnetic material and the terminal magnetically coupling the cover to the terminal
Implementation Method 2
The magnetic material is exposed and is adhered adhesively to the cover
