Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If metallic hooks are used, then strength and durability are improved, but cost and weight increase

Engineering Contradiction:

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent employs a composite construction combining metallic inserts (for strength) with polymer body (for cost-effectiveness and lightweight properties). The metallic inserts are integrally molded into the polymer body, creating a hybrid structure that leverages the advantages of both materials while mitigating their individual disadvantages.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The hook system is divided into distinct functional components: metallic inserts for structural strength, polymer body for housing and cost-effectiveness, and bearings for sliding functionality. This segmentation allows each component to be optimized for its specific function and manufactured separately before assembly.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If plastic hooks are used, then cost and weight are reduced, but strength and durability deteriorate

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The patent employs a composite construction combining metallic inserts (for strength) with polymer body (for cost-effectiveness and lightweight properties). The metallic inserts are integrally molded into the polymer body, creating a hybrid structure that leverages the advantages of both materials while mitigating their individual disadvantages.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The metallic inserts are strategically positioned at critical load-bearing locations within the polymer body, providing localized reinforcement where strength is most needed while maintaining the overall lightweight and cost-effective polymer construction in non-critical areas.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If multiple components are used, then adaptability is improved, but assembly complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple components (metallic inserts, hook members, bearings) into a single integrated assembly process through injection molding. The metallic inserts and hook members are positioned within the mold and molded together with the polymer body in one operation, eliminating the need for separate assembly steps and reducing overall complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The polymer body is designed with multiple cavities and features that can accommodate different configurations of metallic inserts and hook members, allowing a single basic design to serve multiple functions and adapt to various storage needs without requiring completely different components.

Inventive Principle:

Principle #6Universality (Multi-functionality)
