Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional integrated clothes drying rack is used, then the structure is simple and stable, but it occupies a large area and lacks adjustability

Engineering Contradiction:
Improveadjustability of unfolding anglesVSAvoidoccupied area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent applies the dynamics principle by transforming the fixed structure of traditional drying racks into a dynamic, adjustable system. The connecting discs and rotating shafts enable the drying rack to change its configuration between folded and unfolded states, and to adjust to different unfolding angles, thereby improving adaptability while reducing occupied area when folded.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The drying rack is segmented into multiple independent components including first and second connecting discs, third and fourth connecting discs, and rotating shafts. This segmentation allows each component to move and adjust independently, enabling angle adjustment and compact folding while maintaining overall structural integrity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a foldable clothes drying rack is used, then the occupied area is reduced, but the unfolding angle cannot be adjusted and the operation becomes complex

Engineering Contradiction:
Improveoperation simplicityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking module is designed to automatically lock the connecting discs at predetermined angles without requiring manual adjustment or complex operations. The limiting module similarly provides automatic limiting of rotation angles, making the system self-regulating and easy to operate while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent changes the operational parameters by introducing predetermined locking angles through the locking module and limiting module. This allows the drying rack to transition between specific angular positions (folded, partially unfolded, fully unfolded) simplifying the operation compared to continuous manual adjustment while maintaining structural efficiency.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple connecting discs and locking modules are added for angle adjustment, then the adjustability is improved, but the device complexity increases

Engineering Contradiction:
Improveangle adjustabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connecting discs serve multiple functions: they connect different sections of the drying rack, enable rotation for angle adjustment, and work with the locking module to provide predetermined angle locking. This multi-functionality reduces the need for separate components for each function, thereby limiting the increase in device complexity while achieving angle adjustability.

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

Solution Approach 2:

The locking module and limiting module are integrated into the existing connecting disc structure rather than being separate add-on components. The locking blocks are disposed on the connecting discs themselves, and the limiting holes are formed in the connecting discs, merging the angle control functions with the structural connecting elements to minimize overall component count.

Inventive Principle:
Principle #5Merging (Combining)
