Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hose is used that requires manual rolling up, then the device structure can be simpler, but the handling becomes more difficult and kinking occurs leading to damage
Solution Approach 1:
The hose device is segmented into a reusable hose component and a replaceable spiral hose cartridge. When the spiral hose becomes damaged or worn, only the cartridge needs to be replaced rather than the entire hose device, simplifying maintenance while providing the benefits of a spiral design that prevents kinking and eliminates manual rolling.
Solution Approach 2:
The spiral hose provides dynamic flexibility through its coiled structure, allowing it to extend and retract naturally during use. This dynamic design eliminates the need for manual rolling while preventing kinking, as the spiral structure absorbs movement and deformation without damage.
2Stability of the object's composition
If the spiral hose is made more elastic to improve return force, then the hose can return better to original position, but the hose may become too flexible and cause instability
Solution Approach 1:
Different sections of the spiral hose have different properties optimized for their specific functions. The spiral structure provides elasticity and return force where needed, while the overall hose construction maintains sufficient rigidity for stable positioning. The hose carrier device also provides localized support to prevent excessive flexibility from causing instability.
3Stability of the object's composition
If the rolling bodies are made larger to improve stability, then the device support surface increases, but the device becomes harder to maneuver and less portable
Solution Approach 1:
The rolling bodies are designed with asymmetric characteristics where at least one wheel can be steered independently. This asymmetric steering capability allows the device to achieve stable support from the rolling bodies while maintaining excellent maneuverability, as the steerable wheel enables tight turning radii and easy direction changes without requiring large wheel sizes.
4Length of moving object
If the hose is made longer to increase working distance, then the coverage area increases, but the hose becomes more prone to kinking and damage
Solution Approach 1:
The spiral hose design provides dynamic flexibility that increases with length without proportionally increasing vulnerability to damage. The coiled structure naturally absorbs movement and prevents kinking even in longer hoses, allowing extended working distance while maintaining reliability. The elastic return force of the spiral structure keeps the hose organized and prevents tangling throughout its length.

Function Achieved in This Case
The solution provides enhanced stability, prevents hose kinking and damage, and allows for easy handling and portability, ensuring the device remains grounded during overhead use.
Implementation Method 1
a spiral hose, which is intended in particular for elastic deformation, so that, in particular, a distance between turns of the spiral-shaped outer shape can be increased by an operator to change an extension of the spiral hose by the application of force

AI summary
The cleaning device has a device housing (10), a chassis (12), and a tube device comprising a spiral coiled tube (36) for elastic deformation, where the tube (36) is formed as a high-pressure tube. The chassis has rolling bodies (14, 16, 18), which are formed for clamping a device-supporting surface. One of the rolling bodies is laterally projected over a device base contour of the device housing. The chassis is formed by a stand. One of the rolling bodies is pivotably supported around a steering rotation axis (24). The stand is formed by a unit separated from the housing.
