Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If magnets are adhered to inner walls by glue, then assembly is simple, but assembly accuracy is poor and magnets are easily dropped during high-speed rotation

Engineering Contradiction:
Improvemagnet assembly simplicityVSAvoidmagnet placement accuracy
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent introduces a magnetic cabin structure as an intermediary component between the magnet and the block. The magnetic cabin with retaining wall acts as a mediator that holds the magnet securely through physical containment rather than chemical adhesion, solving both the simplicity and precision requirements simultaneously.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If magnets are adhered to inner walls by glue, then assembly process is simple, but assembly accuracy is poor and magnets are easily dropped during high-speed rotation

Engineering Contradiction:
Improvemagnet assembly simplicityVSAvoidmagnet retention during rotation
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The magnetic cabin structure serves as a reliable intermediary that physically contains the magnet through its retaining wall design. This mechanical containment structure replaces the unreliable glue adhesion, ensuring magnet retention during high-speed rotation while maintaining assembly simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If elasticity of central blocks is adjusted by replacing springs, then elastic force can be changed, but adjustment is troublesome and requires disassembly

Engineering Contradiction:
Improveelastic force adjustabilityVSAvoidadjustment convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements a dynamic adjustment mechanism where the spring depth can be continuously varied within a defined range. The gear-adjusting piece allows users to dynamically change the spring compression depth without disassembly, transforming a static spring replacement process into a dynamic, adjustable system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adjustment mechanism is designed to be user-operable without requiring external tools or complex disassembly procedures. Users can directly adjust the spring depth through the gear-adjusting piece, enabling self-service elasticity adjustment.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If elasticity of central blocks is adjusted by changing screw depth, then elastic force can be changed, but adjustment requires tools and is troublesome

Engineering Contradiction:
Improveelastic force adjustabilityVSAvoidadjustment convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The gear-adjusting piece is designed as a hand-operable mechanism that eliminates the need for external tools. Users can directly manipulate the gear structure to adjust spring depth, transforming a tool-dependent adjustment process into a self-service operation.

Inventive Principle:
Principle #25Self-service

5Device complexity

If no visible gear mark is provided on central blocks, then structure is simple, but players cannot accurately adjust to desired elastic force positions

Engineering Contradiction:
Improvecentral block structure simplicityVSAvoidadjustment position accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent uses visual indicators (gear marks or transparent windows showing internal gear positions) to provide feedback on the adjustment state. This visual signaling system allows players to accurately determine their adjustment position without adding complex mechanical structures.

Inventive Principle:
Principle #32Color changes

6Device complexity

If magnets are invisible in corner blocks and edge blocks, then structure is simple, but players cannot determine if magnets are in correct positions or falling off

Engineering Contradiction:
Improvemagnet structure simplicityVSAvoidmagnet position detectability
Core Design Contradiction:
Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The magnetic cabin structure incorporates transparent or translucent materials that allow visual detection of magnet presence and position. This transparency feature enables players to observe whether magnets are correctly installed and whether they remain in place during rotation, without adding complex detection mechanisms.

Inventive Principle:
Principle #32Color changes

AI summary

A magic cube with visible magnetic cabins includes a central shaft piece, six central blocks, eight corner blocks, and twelve edge blocks. Corner block magnetic cabins and edge block magnetic cabins are respectively arranged on the corner blocks and the edge blocks. Magnets and magnetic pieces are respectively arranged in the corner block magnetic cabins and the edge block magnetic cabins. Elastic force between the central blocks and the central shaft piece is adjusted by gear adjusting pieces arranged in the central blocks. By arranging the corner block and edge block magnetic cabins, stability of installation positions of the magnets and magnetic pieces is ensured and an assembly accuracy is improved. The magnetic pieces do not fall off or offset during use. By arranging the gear adjusting pieces in the central blocks, it is convenient to quickly adjust elastic force between the central blocks and the central shaft piece.
