Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If custom-designed sealing and reinforcement elements are manufactured for each body shape and cavity, then the sealing and reinforcement effectiveness is improved, but the development and manufacturing costs increase significantly

Engineering Contradiction:
Improvesealing effectivenessVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a basic element with a standardized coupling element that can be combined with various additional elements to create sealing and reinforcement solutions for different cavity shapes and sizes. This modular approach allows a single basic element design to serve multiple applications across different body shapes, reducing development costs while maintaining effective sealing and reinforcement.

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

Solution Approach 2:

The patent segments the sealing and reinforcement element into a basic element and additional elements that can be separately manufactured and then combined through coupling elements. This segmentation allows each component to be optimized and manufactured independently using cost-effective processes, while the assembled combination provides the required sealing and reinforcement for specific cavity configurations.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If individually manufactured insulating elements are produced for each cavity, then the insulation precision is improved, but the productivity decreases and costs increase

Engineering Contradiction:
Improveinsulation precisionVSAvoidproduction volume
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The basic element is designed as a universal component that can be used across multiple cavity applications. By standardizing the basic element design while allowing customization through additional elements, the system achieves high insulation precision for each specific cavity while maintaining high productivity through repeated use of the same basic element design in mass production.

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

Solution Approach 2:

The basic element is pre-designed and standardized in advance, allowing it to be manufactured in large quantities using efficient production processes. This preliminary design action enables rapid assembly for different cavity applications without requiring individual customization, thereby maintaining high insulation precision while significantly improving productivity.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If a single standardized insulating element is used for all applications, then the manufacturing cost decreases, but the adaptability to different cavity shapes is reduced

Engineering Contradiction:
Improvemanufacturing costVSAvoidcavity shape adaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The insulating element is segmented into a standardized basic element and configurable additional elements. The basic element provides the core insulation function and can be manufactured in large quantities at low cost, while additional elements can be added to adapt the overall solution to different cavity shapes and sizes, thereby maintaining both cost-effectiveness and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system allows dynamic configuration by combining the standardized basic element with different additional elements depending on the specific application requirements. This dynamic adaptability enables the same basic element to be effectively used across various cavity shapes and sizes without sacrificing manufacturing efficiency.

Inventive Principle:
Principle #15Dynamics
