1Ease of operation

If conventional lift structures with various components are used, then height adjustment function is achieved, but assembly process becomes complicated and assembly efficiency decreases

Engineering Contradiction:

Improveheight adjustment functionVSAvoidassembly process complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple components (spherical bodies, guiding rails, magnetic elements) into an integrated sliding module assembly. The spherical bodies are positioned within the frame body structure, and the magnetic elements are embedded in the guiding rails, creating a unified lift mechanism that reduces assembly steps while maintaining height adjustment functionality.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces traditional mechanical fastening and positioning systems with a magnetic field-based positioning system. The magnetic elements in the guiding rails interact with the spherical bodies to provide automatic positioning and retention, eliminating the need for complex mechanical clips, screws, or interlocking mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent replaces traditional mechanical fastening and positioning systems with a magnetic field-based positioning system. The magnetic elements in the guiding rails interact with the spherical bodies to provide automatic positioning and retention, eliminating the need for complex mechanical clips, screws, or interlocking mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces magnetic elements as an intermediary force between the spherical bodies and the guiding rails. This magnetic interaction serves as a mediator that provides both positioning stability and smooth movement, allowing the spherical bodies to slide freely while maintaining precise positioning without direct mechanical contact constraints.

Inventive Principle:

Principle #24Intermediary (Mediator)
