Solution Overview
Problem
Traditional time switches, particularly the spring-type rocker switches, face issues with unstable performance, difficult assembly, and single-button design, leading to manufacturing challenges and poor user experience due to complex structure and interference with appliance panels.
Innovation Solution
A controllable time switch design featuring a switch housing with a control circuit board, input and output terminals, a warped plate connected via a rotating shaft with a spring, and a timing rotary switch connected to the circuit board, allowing for easy installation and adjustment, along with a waterproof rubber ring and buckles for assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional spring-type rocker switch structure is used, then good hand feeling is achieved, but unstable performance and difficult assembly occur
Solution Approach 1:
The switch body is divided into modular components: a housing containing the circuit board, a separate warped plate mechanism with rotating shaft, and a distinct timing rotary switch assembly. This segmentation allows each component to be optimized independently - the warped plate provides stable mechanical action while the modular design simplifies assembly and replacement.
2Ease of operation
If traditional time switch with rotating shaft holes and ship-shaped button is used, then button pulling action is realized, but manufacturing and assembling become troublesome
Solution Approach 1:
The rotating shaft is integrated directly into the warped plate structure, eliminating the need for separate rotating shaft holes in the housing. The ship-shaped button is merged with the timing rotary switch assembly, allowing the entire timing mechanism to be replaced as one unit. This combining of functions reduces assembly steps and manufacturing complexity.
3Adaptability or versatility
If accessories are scattered in traditional time switch design, then assembly flexibility is provided, but assembly stability deteriorates
Solution Approach 1:
The housing is designed with universal mounting features including standardized screw holes and a clip structure that can accommodate different installation scenarios. The integrated warped plate with built-in rotating shaft serves multiple functions: providing mechanical leverage for the button, enabling rotation for timing adjustment, and ensuring stable electrical contact. This multi-functionality maintains flexibility while improving assembly stability.
4Device complexity
If ship-shaped button is single and replacement is difficult in traditional design, then simple structure is maintained, but maintenance and replacement become difficult
Solution Approach 1:
The timing rotary switch assembly containing the ship-shaped button is designed as a separate, self-contained module that can be independently removed and replaced. This segmentation allows the button assembly to be replaced without disassembling the entire switch mechanism, significantly improving maintenance ease while keeping the overall structure relatively simple.
