Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If specialized profile elements are provided for covering, guiding, and connecting components, then functional versatility is improved, but manufacturing cost and complexity increase

Engineering Contradiction:
Improvefunctional versatilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single profile element with a trapezoidal cross-section that can perform multiple functions (covering, guiding, and connecting components) rather than requiring separate specialized profile elements for each function. This reduces the variety of different parts needed while maintaining functional versatility.

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

Solution Approach 2:

The patent merges multiple functions into a single profile element structure. The trapezoidal cross-section integrates covering, guiding, and connecting capabilities in one component, eliminating the need for multiple separate specialized elements and thereby reducing manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If specialized profile elements are provided for covering, guiding, and connecting components, then functional versatility is improved, but manufacturing cost increases

Engineering Contradiction:
Improvefunctional versatilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The universal profile element design allows a single standardized component to replace multiple specialized elements, reducing the total number of different parts that need to be manufactured and stocked, thereby lowering manufacturing costs while maintaining functional versatility.

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

Solution Approach 2:

The patent uses parameter changes by varying the dimensions and geometry of the trapezoidal cross-section to adapt the same basic profile element design for different applications (covering, guiding, connecting), allowing cost-effective manufacturing through standardized production processes.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the side sections are made narrower (less than 15% of base section extent), then manufacturing simplicity is improved, but structural stability may worsen

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The patent optimizes the geometric parameters of the trapezoidal cross-section, specifically setting the side sections to be less than 15% of the base section extent, to achieve a balance between manufacturing simplicity and structural stability. This parameter optimization allows easy manufacturing while maintaining adequate structural integrity.

Inventive Principle:
Principle #35Parameter changes

AI summary

A profile element for covering, guiding, and/or connecting components of a hardware assembly is described. This element comprises a base section and side sections arranged on opposite longitudinal sides of the base section. The facing sides of the side sections each have an inner surface that forms an angle of less than 90° with the base section. A hardware assembly incorporating such a profile element is also described.
