Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing convertible electrical switches require disassembly to convert between push-button and switch modes, are prone to assembly failures, and lack user-friendly conversion mechanisms.
Innovation Solution
A convertible electrical switch with a pivotable rocker arm and activation elements guided by windows and a spring, allowing conversion between stable positions without disassembly, using a sliding assembly and guided movement to ensure robust operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spring is located inside the switch requiring disassembly to insert or remove, then the conversion between push-button and switch modes is possible, but the ease of operation deteriorates due to the need for disassembly and technical expertise
Solution Approach 1:
The activation element is nested within the rocker arm structure, with the spring positioned inside the activation element. This nested configuration allows the components to be compact while maintaining the ability to convert between modes through simple rotation of the activation element, eliminating the need for disassembly.
Solution Approach 2:
The activation element is pre-configured with a window and projection geometry that enables automatic engagement with the rocker arm when rotated to the active position. The spring is pre-positioned to automatically push the activation element into the rocker arm window, creating the push-button effect without requiring user disassembly or adjustment.
2Adaptability or versatility
If the spring is required to bring the rocker arm to the OFF position, then the push-button function is achieved, but the device complexity increases due to terminal configuration requirements
Solution Approach 1:
The activation element serves multiple functions: it acts as a lever for user input, a guide for spring force transmission, and a positioning mechanism for engaging with the rocker arm. The window geometry and projection design allow a single component to manage both the push-button activation and the rockerm arm positioning without requiring additional terminals or complex configurations.
3Ease of manufacture
If disassembly and assembly is required for conversion, then the spring can be installed, but the reliability deteriorates due to possible assembly failures and incorrect positioning
Solution Approach 1:
The activation element is designed to self-align and self-engage with the rocker arm through its window geometry and projection features. When the activation element is rotated to the active position, the spring automatically pushes it into the correct position where the projection engages the window, creating a self-locking mechanism that eliminates assembly errors and ensures reliable operation without requiring technician expertise.

Function Achieved in This Case
Facilitates quick and safe conversion between switch and push-button modes, reducing assembly risks and extending the switch's lifespan by preventing unnecessary spring compression.
Implementation Method 1
by action of a spring coupled to the activation element, and pushes the operating rocker arm to a single stable position

AI summary
The invention relates to a convertible electrical switch with an operating rocker arm mounted on a base of a switch body in a pivotable manner between three stable ON and OFF positions of the switch, comprising an activation element for each ON position, which, when the corresponding activation element is in an activation position and connected to the rocker arm, pushes the rocker arm to a stable position converting the switch into a push-button, and wherein the activation elements are arranged in guided assembly, so that in the inactive position the corresponding activation element passes through the window without pushing the rocker arm, while in the activation position the corresponding activation element is configured to push the rocker arm after a rotation of said activation element is established, so that the rocker arm is moved together with the activation element by action of the spring.
