Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning device operates only at a fixed position or depth in the liquid environment, then the device structure is simple, but the device cannot effectively adjust positions and depth to clean the bottom, wall surfaces, and liquid surface in an all-round manner
Solution Approach 1:
The patent applies the dynamics principle by making the cleaning device capable of dynamic position adjustment and motion state switching. The device can transition between different motion states (floating on surface, submerged, climbing walls) and adjust its depth and position dynamically, allowing it to clean the bottom, wall surfaces, and liquid surface comprehensively while maintaining a relatively simple overall structure
Solution Approach 2:
The patent implements universality by designing a multi-functional cleaning device that can perform multiple cleaning tasks (bottom cleaning, wall cleaning, surface cleaning) with a single integrated apparatus. The device incorporates universal components such as cleaning members, propulsion mechanisms, and buoyancy control systems that enable it to adapt to different cleaning scenarios without requiring separate specialized devices
2Productivity
If the cleaning device uses a fixed motion state, then the device structure is simple, but the operating efficiency and application range are limited
Solution Approach 1:
The patent applies dynamics by implementing a mode switching mechanism that allows the device to transition between different motion states (first motion state for bottom cleaning, second motion state for wall cleaning, third motion state for surface cleaning). This dynamic switching capability enables the device to adapt to different cleaning tasks and improves operating efficiency while maintaining reasonable structural complexity
Solution Approach 2:
The patent utilizes parameter changes by adjusting the buoyancy of the device through a buoyancy cavity and injection openings. By changing the volume of gas or liquid in the buoyancy cavity, the device can alter its overall density and buoyancy parameters, enabling transitions between floating and submerged states, and facilitating efficient movement between different cleaning zones
3Adaptability or versatility
If the cleaning device cannot adjust depth, then the device structure is simple, but the device cannot clean the bottom, wall surfaces, and liquid surface in an all-round way
Solution Approach 1:
The patent applies parameter changes by using a buoyancy cavity with injection openings that allow gas or liquid to be injected to adjust the device's buoyancy. This enables automatic and easy depth adjustment, allowing the device to reach the bottom, maintain position against walls, and surface for liquid cleaning without complex manual intervention
Solution Approach 2:
The patent implements self-service through automatic buoyancy control mechanisms that enable the device to adjust its own depth and position autonomously. The buoyancy cavity system allows the device to self-regulate its floating and sinking, making depth adjustment easy and reducing the need for external control or complex operational procedures
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
Enables all-round cleaning of liquid environments by allowing the apparatus to transition between surface and submerged positions, enhancing cleaning efficiency and reducing costs.
Implementation Method 1
The mode switching member includes a buoyancy cavity, a first adjustment part, and at least one first injection opening. The buoyancy cavity is configured to accommodate gas or liquid... After the at least one first injection opening of the moving apparatus is exposed above a liquid surface, the first adjustment part is turned on to input gas into the buoyancy cavity through the at least one first injection opening, so that the rear portion of the moving apparatus moves toward the liquid surface
