Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a universal track widening system is designed to accommodate different wheel diameters and vehicle configurations, then adaptability is improved, but device complexity increases due to the need for multiple components

Engineering Contradiction:

Improveadaptability to different wheels and vehiclesVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system is divided into two functional segments: a track widening disc that provides the mechanical track widening function, and a centering ring that provides the centering and adaptation function. This segmentation allows each component to be optimized independently, with the centering ring being simplified through plastic injection molding while the disc maintains its structural integrity for load-bearing applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The track widening disc is designed as a universal component that can accommodate different wheel configurations through the interchangeable centering ring. The disc provides a standardized interface for wheel bolts and hub mounting, while the variable centering ring adapts to different wheel diameters and hub tolerances, creating a universal system that reduces the total number of components needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of manufacture

If the centering ring is made from plastic material to reduce production costs, then manufacturing cost is improved, but strength and durability may be compromised

Engineering Contradiction:

Improveproduction costVSAvoidstrength of centering ring

Core Design Contradiction:

Ease of manufactureVSStrength

Solution Approach 1:

The centering ring is designed as a non-load-bearing component that performs its centering function during wheel installation and then transfers all mechanical loads to the track widening disc and wheel hub. Since it is not subjected to driving loads, a cost-effective plastic injection-molded construction is sufficient, eliminating the need for expensive metal materials while maintaining functional adequacy.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The centering ring replaces a potential metal mechanical component with a plastic injection-molded part. The plastic material provides sufficient strength for the centering function during installation, and the design ensures that no permanent mechanical loads are imposed on the centering ring during vehicle operation, substituting a potentially complex metal assembly with a simpler, cheaper plastic component.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If the centering ring is designed with precise dimensions for different wheel diameters, then centering precision is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvecentering precisionVSAvoidvariety of centering ring dimensions

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The centering ring is designed with variable parameters, specifically the outer diameter of the rim centering portion, which can be adjusted to match different wheel diameters and central opening sizes. By changing this single critical parameter while maintaining the same basic design and interface features, the system achieves precise centering for multiple wheel configurations without requiring completely different ring designs, thus managing manufacturing complexity.

Inventive Principle:

Principle #35Parameter changes
