Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines are difficult to move due to time and labor consumption, and existing mobile devices often result in deformed or damaged casters and noisy hydraulic/pneumatic systems, complicating the structure and user experience.
Innovation Solution
A lifting device with a connector, cylindrical pins, and levers connected to a driving device, including an electric motor and speed reducer, allows for vertical movement of support feet, enabling easy raising and lowering of the washing machine, using universal wheels for mobility and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If casters are installed on the bottom support plate to facilitate movement, then the washing machine can be moved more easily, but the wheel bodies are easily deformed and damaged during use
Solution Approach 1:
The patent removes the casters from direct contact with the ground by introducing a lifting device that raises the washing machine body. The casters are extracted from their traditional ground-contact function and repositioned to roll on a support plate that is elevated above the ground, thereby protecting them from deformation and damage while maintaining mobility functionality.
Solution Approach 2:
The patent introduces a support plate as an intermediary element between the casters and the ground. This support plate is lifted above the ground surface, creating a protective barrier that prevents direct contact between the casters and rough ground conditions, thus reducing deformation and damage while still enabling movement through the casters rolling on the elevated plate.
2Reliability
If hydraulic and pneumatic devices are installed to raise and lower the washing machine, then the casters are protected from direct ground contact, but the structure becomes complicated and causes noises
Solution Approach 1:
The patent replaces complex hydraulic or pneumatic lifting systems with a simpler mechanical linkage system. The lifting device uses a support plate connected to the washing machine body through mechanical linkages that can be manually operated to raise and lower the machine, eliminating the need for noisy and complex fluid-based systems while achieving the same protective function.
Solution Approach 2:
The lifting device is designed to be manually operable by the user without requiring external power sources or complex control systems. The mechanical linkages allow the user to directly raise and lower the washing machine body, making the system self-sufficient and avoiding the complexity of powered hydraulic or pneumatic systems.
3Device complexity
If manual lifting is used to move the washing machine, then the structure remains simple, but it consumes time and labor
Solution Approach 1:
The patent incorporates a crank mechanism that converts rotational motion into vertical lifting motion, similar to how a hand-cranked device operates. This mechanical copying of motion transformation allows the user to efficiently raise and lower the washing machine with minimal effort, reducing time and labor consumption while maintaining structural simplicity through pure mechanical means.
