Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lifting mechanisms are used for functional assemblies, then the cleaning function is improved, but the device complexity increases and manufacturing cost increases
Solution Approach 1:
The patent combines multiple lifting mechanisms into a single integrated lifting mechanism. The first and second functional assemblies share common components including the driving assembly, rotating members, and cables, thereby reducing overall device complexity while maintaining the ability to independently lift and lower each functional assembly for versatile cleaning operations.
2Adaptability or versatility
If multiple lifting mechanisms are used for functional assemblies, then the cleaning function is improved, but the manufacturing cost increases
Solution Approach 1:
The patent merges multiple lifting mechanisms into one shared mechanism, reducing the total number of components that need to be manufactured and assembled. The first and second functional assemblies utilize common parts such as the driving assembly, rotating members, and cables, which simplifies manufacturing processes and lowers production costs while still enabling independent control of each assembly.
Solution Approach 2:
The lifting mechanism is designed with universal components that serve multiple functions. The driving assembly, rotating members, and cables are shared between the first and second functional assemblies, allowing a single mechanism to perform the lifting function for both assemblies, thereby reducing manufacturing cost while maintaining versatility.
3Device complexity
If a single lifting mechanism is used for multiple functional assemblies, then the device complexity is reduced and manufacturing cost is reduced, but the control precision may be affected
Solution Approach 1:
The patent segments the lifting control by providing independent cables for the first and second functional assemblies. Each cable can be independently wound or unwound on its respective rotating member, allowing precise independent control of each functional assembly's lifting and lowering operations, thereby maintaining control precision despite using a shared driving mechanism.
