Solution Overview

Problem

The integration of multiple functions in vehicle design often leads to interference between components, necessitating additional expensive mechanical protection systems, which increases production costs and complexity.

Innovation Solution

A modular closure element for vehicle sheets that combines the function of replacing a component with mechanical protection by using a first part to cover an orifice, a second part that fits elastically, and attachment means to secure the element to the vehicle, eliminating the need for separate protection components and reducing interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If multiple functions are integrated in vehicle design to reduce production costs, then production costs are reduced, but interference between components occurs requiring additional expensive mechanical protection systems

Engineering Contradiction:
Improveproduction costVSAvoidcomponent interference
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The closure element combines multiple functions into a single component: it closes the orifice to replace removed functionality, provides mechanical protection through the attachment means to the pipe, and manages clearance between components. This merging eliminates the need for separate protection components while maintaining all necessary functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The closure element is designed as a universal component that performs multiple roles: it acts as a closure for the orifice, provides mechanical protection for the pipe through the attachment means, and manages spatial relationships with other components. This multi-functionality allows a single component to address multiple design requirements simultaneously.

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

2Reliability

If additional mechanical protection systems are added to prevent component interference, then component protection is improved, but production costs increase

Engineering Contradiction:
Improvecomponent protectionVSAvoidproduction cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The attachment means is integrated directly into the closure element, combining the protection function with the closure function in a single component. This eliminates the need for separate protection components, maintaining reliability while reducing the number of parts and production costs.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If separate protection components are used to prevent pipe wear, then pipe protection is improved, but device complexity increases

Engineering Contradiction:
Improvepipe protectionVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment means providing pipe protection is integrated into the closure element itself, eliminating the need for separate protection components. This reduces device complexity by consolidating multiple functions into a single component while maintaining pipe protection capability.

Inventive Principle:
Principle #5Merging (Combining)
