Wire Installation Mechanism With Tool-Guided Release Lever Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional switch or socket plate assemblies have visible screws, which are aesthetically unpleasing, especially when made of metal with decorative surface treatments. Additionally, existing screwless installation systems face issues with wire disconnection, misalignment, and shock hazards during installation.
Innovation Solution
The proposed electrical device features a rocker assembly with an outer and inner rocker, a switch assembly with multiple release levers, and a terminal spring mechanism that allows for easy insertion and removal of stripped wires using a tool-operated release lever, ensuring secure and hassle-free installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional switch or socket plates are made of metal with decorative surface treatments, then aesthetic appearance is improved, but mounting screws become visible which is aesthetically unpleasing
Solution Approach 1:
The patent extracts the mounting function from visible external screws and relocates it to hidden internal mechanisms. The modular design separates the decorative faceplate from the mounting hardware, allowing screws to be concealed within the assembly structure rather than exposed on the front surface.
Solution Approach 2:
The patent employs nested construction where mounting screws and fastening mechanisms are embedded within the multi-layered switch or socket assembly. The faceplate, mounting plate, and internal components are nested together to hide fastening elements while maintaining structural integrity.
2Ease of manufacture
If conventional switch or socket plates are made of non-metallic materials, then mounting screws can be hidden, but aesthetic appearance and durability are compromised
Solution Approach 1:
The patent uses composite construction combining metallic and non-metallic materials in different layers. The internal mounting structure can use metal for strength and screw concealment, while the external faceplate uses decorative materials for aesthetic appearance, achieving both goals simultaneously.
3Ease of operation
If conventional screwless installation systems use terminal spring and release lever mechanisms, then wire installation is simplified, but wire disconnection and mechanism misalignment occur leading to safety hazards
Solution Approach 1:
The patent incorporates preliminary alignment features such as guide rails, positioning pins, and pre-configured terminal springs that ensure proper mechanism alignment before wire insertion. This prevents misalignment during operation while maintaining ease of installation.
Solution Approach 2:
The patent introduces intermediary components such as guide structures, alignment pins, and controlled release mechanisms that mediate between the user's installation actions and the terminal spring-release lever system. These intermediaries prevent direct misalignment and ensure reliable wire connection while preserving operational simplicity.
4Ease of operation
If conventional release levers are designed for hand operation, then installation is simplified, but misguidance and misalignment may result in shock hazards
Solution Approach 1:
The patent introduces intermediary guide structures, alignment pins, and tool interface features that mediate between hand operation and the release lever mechanism. These intermediaries ensure proper alignment and controlled actuation, preventing misguidance while maintaining ease of operation.
Solution Approach 2:
The patent incorporates electrical safety features such as insulated components, grounded shielding, and controlled circuit disconnection mechanisms that substitute or supplement the mechanical release lever system. These features reduce shock hazards while preserving the simplicity of manual operation.
