Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If portable dryers are used to speed up drying, then drying efficiency is improved, but temperature control is poor causing burn risks

Engineering Contradiction:
Improvedrying efficiencyVSAvoidburn risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the temperature parameter from high-temperature rapid drying to controlled low-temperature drying at 50°C. This parameter change maintains drying efficiency while eliminating burn risks, allowing safe manual handling and repositioning of the device during operation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses a simple heating element with insulating panels instead of complex high-temperature systems. The design prioritizes safety and simplicity over maximum heating capability, using readily manageable materials and a straightforward heating mechanism that operates safely without advanced temperature control systems.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Productivity

If fixed-position dryers are used, then heating efficiency is improved, but adaptability to different garment lengths is poor

Engineering Contradiction:
Improveheating efficiencyVSAvoidadaptability to different garment lengths
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent transforms the fixed-position dryer into a dynamic, adjustable system. The heating element can be repositioned vertically along the drying rack to match different garment lengths, while maintaining its heated position for efficient drying. This dynamic adjustment capability provides both adaptability and sustained heating efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The drying system is segmented into adjustable components, allowing the heating element to be independently positioned at different heights. This segmentation enables customization for various garment types while maintaining the integrity and heating function of each component.

Inventive Principle:
Principle #1Segmentation

3Productivity

If large electric dryers are used, then drying speed is improved, but space occupation and electricity consumption increase

Engineering Contradiction:
Improvedrying speedVSAvoidspace occupation
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent merges the drying function with a compact rack structure, combining storage and drying capabilities in one space-efficient unit. The heating element is integrated into a small footprint design that occupies minimal space while maintaining effective drying speed for small to medium loads.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the essential drying function from large commercial dryers, creating a minimized version that retains core heating and drying capabilities while removing unnecessary bulk and space requirements. The design focuses on only the critical drying elements needed for efficient operation.

Inventive Principle:
Principle #2Taking out (Extraction)
