Wall Switch Lever Assembly for Reduced Button Travel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted electrical switches require significant actuation button movement to change functional positions, compromising aesthetics and requiring disassembly of the pivoting mechanism for button or lever part replacement.
Innovation Solution
Incorporating lever parts between the actuation button and pivoting mechanism, with one end attached to a coupling panel and the other supported on the pivoting mechanism, allowing reduced actuation button movement and enabling replacement without disassembling the pivoting mechanism, using an arched configuration and protrusions for efficient transmission and flexible pins for assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If lever parts are incorporated between the actuation button and pivoting mechanism to reduce button movement angle, then aesthetic appearance is improved, but device complexity increases
Solution Approach 1:
The lever parts are integrated within the existing switch structure, nested between the actuation button and the pivoting mechanism. The lever parts share space with other components, reducing overall device complexity while achieving the aesthetic goal of reduced button movement angle.
Solution Approach 2:
The actuation mechanism is segmented into distinct functional parts: the actuation button, the lever parts, and the pivoting mechanism. This segmentation allows each component to be optimized independently - the lever parts can be designed with specific geometries to minimize button movement while maintaining ease of assembly and replacement.
2Ease of repair
If lever parts are attached to coupling panel and supported on pivoting mechanism, then button replacement becomes easier, but manufacturing complexity increases
Solution Approach 1:
The lever parts are pre-assembled with the coupling panel and button in a standardized configuration during manufacturing. This preliminary assembly creates a modular unit that can be easily replaced as a complete assembly, simplifying repair operations while the standardized design processes mitigate manufacturing complexity through repetition and standardization.
Solution Approach 2:
The lever parts serve multiple functions: they transmit actuation force, provide structural support, and enable easy replacement through standardized attachment to the coupling panel. This multi-functionality reduces the need for separate specialized components, thereby managing manufacturing complexity while achieving ease of repair.
3Productivity
If arched configuration with protrusions is used for lever parts, then actuation efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The lever parts feature an arched (curved) configuration instead of straight lines. This curvature is optimized to provide mechanical advantage during actuation, improving efficiency by distributing forces more effectively. The standardized arched geometry can be manufactured using precise molding or machining processes, where the curvature radius and profile are controlled parameters that balance actuation efficiency with manufacturability.
Solution Approach 2:
The protrusions on the lever parts have specific dimensional parameters (size, shape, position) that are optimized to achieve the desired actuation efficiency. By carefully selecting and controlling these parameters within tight tolerances during manufacturing, the design achieves high actuation efficiency while maintaining feasible manufacturing precision requirements through standardized parameter sets.

Implementation Method 1
Incorporating lever parts between the actuation button and pivoting mechanism, with one end attached to a coupling panel and the other supported on the pivoting mechanism
Implementation Method 2
the actuation button, when pressed, contacts a middle area of said lever parts... the pivoting angle of the actuation button is reduced, reducing the actuation angle without reducing the effective angle
