Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If fixed locations for article holders are determined by vehicle manufacturers, then installation simplicity is improved, but user customization and convenience are worsened

Engineering Contradiction:
Improveinstallation simplicityVSAvoiduser customization
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The attachment system is divided into separate components: a fixed track structure integrated into the vehicle and removable attachment devices that can be independently positioned. This segmentation allows the track to remain simple for manufacturing while enabling users to customize the position and type of attachment devices according to their needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from static fixed locations to dynamic reconfigurable positions. The track provides a continuous range of positions along its length, allowing attachment devices to be moved and repositioned flexibly. This dynamic capability enables users to adapt the system to changing needs while maintaining a simple fixed track infrastructure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If attachment devices are made removable and interchangeable, then user customization is improved, but installation complexity and reliability are worsened

Engineering Contradiction:
ImproveinterchangeabilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The attachment device is extracted as a separate removable component from the vehicle structure, allowing it to be independently installed, removed, and replaced. The track remains integrated into the vehicle while the attachment device can be freely positioned and exchanged, simplifying the overall installation process despite the added flexibility.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The track serves as an intermediary element between the fixed vehicle structure and the removable attachment device. This intermediate track system provides a standardized interface that simplifies the connection and disconnection processes, enabling easy interchangeability without requiring complex installation procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If tolerance clearance is provided for easy sliding, then ease of operation is improved, but positioning precision is worsened

Engineering Contradiction:
Improvesliding easeVSAvoidpositioning precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The system uses form-fitting cross-sections of tracks and projections that provide natural guidance and centering. The geometric shape parameters are designed to maintain precise alignment while allowing smooth sliding motion, resolving the conflict between ease of operation and positioning precision through optimized dimensional parameters.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If multiple parallel tracks are used for guidance, then stability and collision safety are improved, but device complexity is worsened

Engineering Contradiction:
Improvecollision safetyVSAvoidtrack structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple parallel tracks are merged into a single integrated track structure that provides the benefits of multiple guidance lines without the complexity of separate independent track systems. The combined structure maintains collision safety through distributed guidance while simplifying the overall device architecture.

Inventive Principle:
Principle #5Merging (Combining)
