Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If castor wheels are directly fixed to the base of shelving units, then movement capability is improved, but structural stability deteriorates

Engineering Contradiction:
Improvemovement capabilityVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent introduces an intermediate fixing bracket as a mediator between the castor wheel and the shelving unit base. This bracket distributes the load across multiple attachment points and provides a more robust connection interface, thereby maintaining movement capability while preventing structural instability and overturning risks associated with direct wheel fixation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If high-quality castor wheels are used to prevent overturning, then stability is improved, but device complexity and cost increase

Engineering Contradiction:
Improveoverturning resistanceVSAvoidwheel system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent segments the wheel system into two functional components: standard castor wheels for movement and an intermediate fixing bracket for structural stabilization. This segmentation allows the use of simpler, less expensive wheels while the bracket provides the necessary stability, thereby reducing overall system complexity and cost while maintaining overturning resistance.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the base of shelving units is modified to accommodate wheels, then movement capability is improved, but manufacturing cost and installation complexity increase

Engineering Contradiction:
Improvemovement capabilityVSAvoidbase modification cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The intermediate fixing bracket serves as a pre-fabricated intermediary component that attaches to the existing shelving unit base without requiring structural modifications. This approach preserves movement capability while avoiding the additional manufacturing costs and installation complexity that would result from modifying the base structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If specialist installation skills are required for wheel installation, then installation reliability is improved, but installation time and productivity decrease

Engineering Contradiction:
Improveinstallation reliabilityVSAvoidinstallation speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The intermediate fixing bracket is designed with self-aligning features and simplified attachment mechanisms that enable non-specialist personnel to install the wheel system reliably. The bracket's geometry and attachment points are configured to guide proper installation without requiring specialized skills, thereby maintaining installation reliability while significantly improving installation speed and productivity.

Inventive Principle:
Principle #25Self-service
