Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional center tube coupling methods are used to connect spindles, then the connection can be achieved, but the installation process becomes complex and requires specialized skills and custom-made tools

Engineering Contradiction:
Improveinstallation safetyVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The center tube coupling apparatus is divided into multiple standardized segments: a center tube component, tie rod end components, and clamp components. Each segment has standardized interfaces that simplify assembly and reduce the need for specialized tools, while maintaining reliable connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling apparatus is designed with universal compatibility to work with various spindle types from different manufacturers. The standardized tie rod end components and clamps can be used across different vehicle models, eliminating the need for custom-made tools and specialized installation skills.

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

2Reliability

If traditional center tube coupling methods are used, then spindles can be connected, but installation time increases significantly for unsophisticated technicians

Engineering Contradiction:
Improveconnection reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The tie rod end components are pre-configured with threaded surfaces and the center tube is pre-equipped with corresponding threaded areas. This preliminary preparation allows for quick assembly by simply rotating and moving the components into place, significantly reducing installation time for technicians of all skill levels.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The complex mechanical assembly process is replaced with a simplified rotation and movement mechanism. The threaded interfaces allow components to be assembled by simple rotational motion rather than complex mechanical fastening procedures, reducing installation time while maintaining connection reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If center tube is coupled to spindles using traditional methods, then connection is achieved, but improper installation may cause safety hazards and vehicle damage

Engineering Contradiction:
Improveease of assemblyVSAvoidsafety hazards
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The tie rod end components are designed with asymmetric features including left and right tie rod ends with different configurations. This asymmetry provides built-in guidance that prevents improper installation, as each component can only be assembled in the correct orientation, eliminating safety hazards from incorrect assembly.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The coupling apparatus incorporates self-aligning and self-locking features through its threaded interfaces and clamp mechanisms. The design allows the components to guide themselves into the correct position during assembly, reducing the risk of improper installation and eliminating the need for highly skilled technicians.

Inventive Principle:
Principle #25Self-service

4Reliability

If traditional coupling methods are used, then spindles can be connected, but the apparatus is not compatible with various spindle designs from different manufacturers

Engineering Contradiction:
Improveconnection securityVSAvoidspindle compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The center tube coupling apparatus is designed with universal interfaces that can accommodate various spindle types from different manufacturers. The standardized tie rod end components and clamp mechanisms can be adapted to different spindle configurations, providing both secure connections and broad compatibility across vehicle models.

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

Solution Approach 2:

The apparatus allows for parameter adjustments in the clamp components and tie rod end configurations to accommodate different spindle dimensions and specifications. This flexibility enables the same basic coupling mechanism to work securely with various spindle designs while maintaining connection reliability.

Inventive Principle:
Principle #35Parameter changes

AI summary

The apparatus includes a first tie rod end component having a first threaded surface and a second tie rod end component having a second threaded surface. The first and second tie rod end components are configured to rotatably couple to a center component in opposite directions. The tie rod end components each include a groove designed to assist a user in determining whether the tie rod ends are properly coupled to the center component. If the groove is visible to a user then the tie-rod end is not screwed in far enough. In contrast, it the groove is hidden that indicates that the tie rod end component and the center component are properly assembled to each other.
