Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hydraulic and pneumatic devices are installed on the bottom support plate to raise and lower the washing machine, then the washing machine can be lifted off the ground to prevent caster deformation, but the structure becomes complicated and noise is generated
Solution Approach 1:
The patent removes the complex hydraulic and pneumatic devices from the system entirely. Instead, it uses a simple electric motor (600W) coupled with a speed reducer to drive a lifting mechanism that raises the washing machine body by 150mm, completely eliminating the need for casters and their associated complexity while maintaining reliability
Solution Approach 2:
The patent replaces the mechanical hydraulic/pneumatic lifting system with an electric-driven lifting mechanism. The electric motor (600W) with speed reducer provides controlled lifting power, substituting the complex fluid-based mechanical system with a simpler electric-mechanical system that reduces both structural complexity and noise
2Reliability
If hydraulic and pneumatic devices are used to lift the washing machine, then caster contact with ground is prevented, but noise is generated affecting user experience
Solution Approach 1:
The patent replaces the noisy hydraulic/pneumatic mechanical systems with an electric motor-driven lifting mechanism. The electric motor provides smooth, controlled lifting without the mechanical noise characteristic of hydraulic pumps or pneumatic actuators, significantly reducing noise pollution while protecting casters from ground contact
Solution Approach 2:
The patent completely removes the hydraulic and pneumatic devices that generate noise. By using an electric motor with speed reducer and a lifting mechanism, the system eliminates the noise-generating components while maintaining the protective function of lifting the machine body off the ground
3Device complexity
If manual lifting is used to move the washing machine, then no additional devices are needed, but time and labor are consuming
Solution Approach 1:
The patent implements an automated lifting system where the electric motor (600W) with speed reducer automatically raises the washing machine body 150mm with the push of a button. This self-service mechanism eliminates the need for manual lifting effort and time, while the simple structure with few moving parts maintains ease of operation
Solution Approach 2:
The patent changes the operational parameter from manual force application to electric power delivery. The 600W motor provides sufficient lifting force to raise the entire washing machine body 150mm, transforming the operation from labor-intensive manual lifting to a simple electrically-driven process that reduces time and effort
