Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch light switches face challenges such as small touch areas, requiring effort to find the touch area, inability to operate from 220V without a neutral, complex structures, and increased risk of touching conductive energized parts, complicating installation in buildings with old wiring systems.
Innovation Solution
A touch light switch design with a detachable second assembly mounted on a first assembly, featuring a large touch area, voltage converters for 220V operation without a neutral, and enhanced antenna arrangement, along with a frame and pogo pins for secure attachment and simplified commutation, using polycarbonate materials for durability and weight reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small touch area is used on the touch pad, then the device structure remains simple, but the user has to make an effort to find the specific touch area
Solution Approach 1:
The touch pad is divided into multiple distinct touch zones (first touch zone, second touch zone, third touch zone) with different functions. Each zone is spatially separated and clearly defined, allowing users to easily locate and operate different functions without confusion, while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the switch is designed to work from 220V without a neutral, then compatibility with old wiring systems is improved, but the device structure becomes more complex
Solution Approach 1:
The touch light switch is designed with multi-functional capability to work in different wiring configurations. It can operate from 220V with neutral, 220V without neutral, and even single-phase three-wire systems. The internal circuitry automatically adapts to different power supply configurations, providing universal compatibility across old and new wiring systems without requiring complex external modifications.
3Ease of manufacture
If conductive parts are exposed for electrical connection, then electrical connection is established, but the risk of touching energized parts increases
Solution Approach 1:
The electrical connection mechanism uses a nested structure where the second assembly contains pogo pins that insert into corresponding receptacles on the first assembly. This nested design allows electrical contacts to be made internally within the housing, keeping conductive parts hidden and inaccessible to users while maintaining reliable electrical connection during assembly and disassembly.
4Adaptability or versatility
If a fixed monolithic structure is used, then manufacturing is simplified, but adaptability to different installation scenarios is reduced
Solution Approach 1:
The switch housing is divided into two separate assemblies: the first assembly containing the base housing and power circuitry, and the second assembly containing the touch pad and control circuitry. These modular units can be manufactured separately and then assembled together, providing installation flexibility while maintaining relatively simple manufacturing processes for each individual component.

AI summary
The invention relates to a field of electric equipment, in particular, to an electric light switch, namely, to a touch light switch to be mounted in a wall of a building.The set of essential features of the present solution enables to achieve such a technical effect as increase of convenience mainly increase of the light weight, the light switching on/off process due to provision of the large area of the touch area on the touch printed circuit board, thus, a high sensitivity on the touch display panel is achieved, i.e., along the entire front area of the device; simplification of mounting of the switch in buildings having old wiring and increase of safety of the device structure. This design of the touch light switch affects the correct operation of the device, thereby enhancing the receipt of signals and decreasing the probability of incorrect commutation of the switch and its failure during mounting.
