Solution Overview

Problem

Existing vehicle fixation systems require multiple components and fixtures for different processing methods, leading to increased weight, cost, and unnecessary structural demands, which are no longer needed after production.

Innovation Solution

A modular fixation system with a single, rotationally symmetrical fixation module per component, designed as a sleeve with an inner thread, that can be used across multiple processing systems with interchangeable circulating parts, reducing the need for multiple fixtures and minimizing weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple fixing modules are arranged in each component for different processing systems, then the vehicle can be fixed in various processing systems, but the weight and structural complexity increase

Engineering Contradiction:

Improvecompatibility with different processing systemsVSAvoidweight of vehicle body

Core Design Contradiction:

Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent implements a universal fixing module design that can be used across multiple processing systems. The fixing module features a standardized threaded bore that accepts different rotating parts (pin, mandrel, rod) depending on the processing requirement. This single multi-functional fixing module replaces what would traditionally require multiple specialized fixing components, thereby reducing weight while maintaining compatibility with wind tunnel testing, paint shop operations, and assembly line processes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The fixing system is segmented into two independent parts: a permanent fixing module integrated into the vehicle body component, and removable rotating parts specific to each processing system. This segmentation allows the heavy permanent structure to be minimized while the specialized functionality is provided by lightweight, interchangeable rotating parts that are attached only when needed.

Inventive Principle:

Principle #1Segmentation

2Reliability

If multiple fixing modules are integrated into components, then the vehicle can be securely fixed in different processing systems, but the manufacturing cost and structural demands increase

Engineering Contradiction:

Improvefixation reliabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By designing a universal fixing module with a standardized threaded interface, the patent enables a single manufacturing process for the fixing module itself, regardless of which processing system it will serve. The variability is shifted to the inexpensive, simple rotating parts (pins, mandrels, rods) that are manufactured separately and interchangeably. This approach reduces the complexity and cost of manufacturing multiple specialized fixing modules while maintaining reliable fixation for each specific application.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple fixing modules are arranged in components, then the vehicle can be fixed in processing systems, but unnecessary structural demands are imposed on the vehicle body

Engineering Contradiction:

Improvefixation capabilityVSAvoidstructural integrity of vehicle body

Core Design Contradiction:

Adaptability or versatilityVSStrength

Solution Approach 1:

The patent segments the fixation system so that only one permanent fixing module is integrated into each vehicle body component, rather than multiple fixed structures. This minimal permanent structure imposes fewer structural demands on the vehicle body. The additional fixation capabilities for different processing systems are achieved through removable rotating parts that attach to the single fixing module, eliminating the need for multiple reinforced mounting points in the vehicle body structure.

Inventive Principle:

Principle #1Segmentation

4Weight of moving object

If a single fixing module is used with interchangeable rotating parts, then weight and cost are reduced, but the device complexity increases

Engineering Contradiction:

Improveweight of fixation systemVSAvoidcomplexity of fixation system

Core Design Contradiction:

Weight of moving objectVSDevice complexity

Solution Approach 1:

Instead of integrating multiple specialized fixing modules directly into the vehicle body (complex permanent structure), the patent inverts the approach by using a single simple permanent fixing module and achieving complexity through interchangeable removable parts. This inversion shifts the complexity from the permanent vehicle body structure to temporary, easily replaceable components, thereby reducing overall system complexity while maintaining versatility.

Inventive Principle:

Principle #13The other way round (Inversion)
