Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple production steps are used to create room dividers with flexible surface design, then manufacturing precision and design flexibility are improved, but device complexity and production time increase

Engineering Contradiction:
Improvesurface design flexibilityVSAvoidproduction process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines heating, pressing, forming, and cavity creation into a single integrated molding process. The mold applies heat and pressure simultaneously to form the room divider with curved surfaces and embedded mounting element cavities in one operation, eliminating the need for separate production steps while achieving complex flexible designs

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The molding process serves multiple functions simultaneously: it heats the fiber composite material, applies pressure for consolidation, forms curved surfaces, creates cavities for mounting elements, and produces the final shaped room divider all in one operation, making the process highly versatile and efficient

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

2Manufacturing precision

If multiple production steps are used to form curves and edges, then manufacturing precision is improved, but productivity decreases

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent combines curve formation, edge definition, and cavity creation into a single molding operation. The mold geometry directly imparts the desired curved surfaces and edges while simultaneously forming cavities for mounting elements, achieving high precision without requiring multiple sequential steps that would reduce productivity

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If fiber composite mats are bonded using traditional methods, then bond strength is improved, but production complexity and time increase

Engineering Contradiction:
Improvebond strength of fiber matsVSAvoidbonding process complexity
Core Design Contradiction:

Solution Approach 1:

The patent utilizes the phase transition of the plastic component from solid to molten state during heating. The plastic melts and flows between fibers, creating strong bonds as it solidifies upon cooling. This phase change enables effective bonding of fiber composite mats through the molding process itself, eliminating the need for separate bonding operations and reducing production complexity

Inventive Principle:
Principle #36Phase transitions
