Multi-Bolt-Pattern Wheel Adaptor With Reduced Hub Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wheel adaptors for six lug bolt patterns are thick and provide undesirable offset, failing to securely adapt a six lug hub to a multi-wheel capable of receiving two different bolt patterns.
Innovation Solution
A wheel adaptor with a cylindrical body featuring specific sets of holes at different radial distances, allowing it to securely couple a six lug hub to a multi-wheel by providing portions of two different bolt patterns, using six bolts for a more secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheel adaptors are used for six lug bolt patterns, then the hub can be adapted to a wheel, but the adaptor is thick and provides undesirable offset
Solution Approach 1:
The adaptor is divided into multiple functional surfaces: a first surface with holes for six lug hub bolts, a second surface with holes for five lug wheel bolts, and a third surface with holes for alternative five lug wheel bolts. This segmentation allows different bolt patterns to be accommodated on different faces of the same adaptor body, enabling versatility without increasing overall thickness.
Solution Approach 2:
The invention utilizes the third dimension by placing different bolt pattern configurations on different surfaces of the adaptor. Instead of extending the adaptor thickness to accommodate multiple bolt patterns, the solution uses the radial and axial positioning of holes on multiple surfaces to create different bolt patterns, effectively using dimensional arrangement rather than size increase.
2Adaptability or versatility
If traditional wheel adaptors are used for six lug bolt patterns, then the hub can be adapted to a wheel, but the connection is not secure
Solution Approach 1:
The adaptor is designed as a universal component that can securely connect six lug hubs to multiple types of five lug wheels. By incorporating multiple sets of holes on different surfaces, a single adaptor can serve multiple wheel configurations, providing both versatility and secure connection through proper structural design and hole positioning.
Solution Approach 2:
The adaptor acts as an intermediary component between the six lug hub and five lug wheel. It provides a secure mechanical interface by receiving six hub bolts on one surface and providing five wheel bolt holes on another surface, mediating the connection between incompatible bolt patterns while maintaining structural integrity and connection security.
3Adaptability or versatility
If traditional wheel adaptors are used for six lug bolt patterns, then the hub can be adapted to a wheel, but the adaptor does not provide portions of two different bolt patterns
Solution Approach 1:
The adaptor structure is segmented into distinct functional zones: a first surface with six lug hole patterns, a second surface with five lug hole patterns, and a third surface with alternative five lug hole patterns. This segmentation allows the adaptor to provide multiple bolt patterns without creating a complex monolithic structure, as each surface can be independently designed and positioned.
Solution Approach 2:
Multiple bolt pattern configurations are merged into a single adaptor body by positioning different hole patterns on different surfaces. The first surface combines with the second and third surfaces to provide comprehensive bolt pattern options, creating a unified adaptor that delivers multiple patterns without requiring multiple separate components.

AI summary
A method of modifying a hub with a wheel adaptor. The wheel adaptor includes a cylindrical body, a first set of holes that includes six symmetrically spaced holes located at a first radial distance, a second set of holes that include three holes located at a second radial distance, and a third set of holes that include another three holes located at a third radial distance. The method includes coupling the wheel adaptor to the hub. The coupling includes passing six symmetrically spaced lugs of the hub through the wheel adaptor at the first set of holes and fastening using six hub lug nuts. The method further includes drilling six holes through the hub using the second set of holes and the third set of holes of the wheel adaptor as drilling guides.
