Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvestructure complexityVSAvoidlifting control precision
Core Design Contradiction:

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.

Inventive Principle:
