Power Adapter Touch Control Eliminates Physical Button
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power adapters and control boxes for LED string lights are separate devices with high material and production costs, poor waterproofing, and short service life due to the presence of physical buttons that can rust and allow water ingress.
Innovation Solution
A power adapter with a sensing control function integrated into a single plug case, featuring a sensor board and controller that senses user operations without a physical button, eliminating the need for a separate control box and enhancing waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate control box with physical button is used to control LED string light, then the control function is achieved, but the device complexity and production cost increase
Solution Approach 1:
The patent combines the power adapter and control box into a single integrated device. The control circuit is integrated into the power adapter housing, eliminating the need for a separate control box. This merging reduces device complexity while maintaining the control function through touch-sensitive operation areas on the power adapter surface.
2Ease of operation
If a physical button is mounted in the control box, then the control function is achieved, but the waterproof capability deteriorates
Solution Approach 1:
The patent replaces the mechanical physical button with a touch-sensitive control interface. The control areas are formed directly on the surface of the power adapter housing, allowing user interaction through touch without requiring any mechanical moving parts or openings that would compromise waterproof sealing.
3Ease of operation
If a physical button with metal dome is used in the control box, then the control function is achieved, but the service life decreases due to rust
Solution Approach 1:
The patent eliminates the metal dome physical button entirely and replaces it with a touch-sensitive control interface integrated into the power adapter housing. This substitution removes the metal component that would be susceptible to rust and degradation, thereby extending the service life of the control mechanism.
4Ease of operation
If separate power adapter and control box are manufactured individually, then the control function is achieved, but the material and production cost increase
Solution Approach 1:
The patent integrates the control circuit and housing into the power adapter assembly, eliminating the need for a separate control box. This consolidation reduces the total amount of materials required and simplifies the manufacturing process by reducing the number of separate components that need to be produced, assembled, and tested.
