Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a self-power wireless switch is designed with existing components, then power generation function is achieved, but the operation requires excessive force and generates noise
Solution Approach 1:
The patent combines the generator bar, elastic member, and upper body into an integrated rotating assembly. The generator bar is disposed on the upper body and rotates together with it, eliminating the need for separate mounting mechanisms and reducing the total number of components while maintaining the self-power generation function.
Solution Approach 2:
The patent introduces a rotating shaft that enables the upper body and generator bar to rotate dynamically during switch operation. This rotational motion, combined with the elastic member, creates a lever mechanism that reduces the force required to press the switch while generating power through the rotating generator bar.
2Ease of manufacture
If multiple components are used to achieve self-power generation, then power supply function is realized, but manufacturing cost increases
Solution Approach 1:
The patent merges the generator bar with the upper body structure, where the generator bar is disposed on the upper body and rotates together with it. This integration eliminates separate mounting brackets, fasteners, and alignment mechanisms, simplifying the manufacturing process and reducing assembly steps.
Solution Approach 2:
The upper body serves multiple functions: it provides structural support, houses the generator bar, acts as a rotating element for the lever mechanism, and interfaces with the switch cover. This multi-functionality reduces the need for additional specialized components.
3Power
If a simple structure is used, then manufacturing cost is reduced, but the switch may not provide sufficient power generation
Solution Approach 1:
The rotating shaft enables dynamic rotation of the upper body and generator bar during switch pressing. This rotational motion allows the generator bar to effectively cut through magnetic field lines (in electromagnetic generators) or deform piezoelectric elements, maximizing power generation from the relatively simple structure.
Solution Approach 2:
The elastic member, preferably a torsion spring, introduces elastic deformation and energy storage capability into the system. This elastic element smooths out the power generation process by storing energy during compression and releasing it during rotation, ensuring consistent power output despite the simple mechanical structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a softer button operation feel, allowing users to press the switch with minimal force, and reduces manufacturing costs through simplified components and structure, while enabling easy expansion of switch members for controlling multiple appliances.
Implementation Method 1
a generator disposed on a bottom surface of the PCB and supplying power to the PCB, wherein, when the user presses the switch cover, while the upper body rotates, a pressure is applied to a generator bar disposed on the generator to generate power
Implementation Method 2
An elastic member may be disposed between the generator bar and the upper body. The elastic member may include a torsion spring
Implementation Method 3
when the self-power wireless switch is pressed, the operation feeling is softened by using the lever principle based on the rotating shaft formed at one side of the lower body so that the user may press the self-power wireless switch with the little force
