Multi-Bolt Wheel Adaptor Structure With Reduced 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 six symmetrically spaced holes and additional sets of holes at different radial distances, allowing it to securely couple a six lug hub to a multi-wheel by providing two different bolt patterns, using six bolts for a more secure connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional thick wheel adaptors are used to adapt a six lug hub to a multi-wheel, then the hub and wheel can be coupled together, but the offset becomes undesirable and the connection stability is reduced
Solution Approach 1:
The wheel adaptor is divided into two separate adaptors: a first wheel adaptor with a first bolt pattern and a second wheel adaptor with a second bolt pattern. These two adaptors work together to bridge the six lug hub to the multi-wheel, replacing the traditional single thick adaptor. This segmentation reduces the overall offset while maintaining adaptability.
Solution Approach 2:
Instead of using a single thick adaptor in one dimension, the solution uses two thinner adaptors arranged in sequence, effectively distributing the adaptation function across multiple components. This dimensional approach reduces the offset issue by spreading the connection points across two separate adaptor bodies rather than one thick body.
2Reliability
If traditional wheel adaptors are used, then the hub and wheel can be coupled, but the connection stability and tight fit are insufficient
Solution Approach 1:
The wheel adaptor system is segmented into two separate adaptors, each optimized for specific bolt patterns. This segmentation allows each adaptor to be thinner and better fitted to its specific interface, improving connection stability and tight fit at each interface, even though the overall system has more components.
Solution Approach 2:
The first and second wheel adaptors together provide universal adaptability to multiple bolt patterns (5x4.5 inches and 5x5.5 inches) while maintaining secure connections. Each adaptor is designed with specific hole patterns that collectively provide multi-functionality, allowing the same adaptor pair to work with different wheel configurations.
3Device complexity
If a single wheel adaptor is used to provide both bolt patterns, then the structure is simpler, but the offset becomes undesirable and connection stability is reduced
Solution Approach 1:
The single thick adaptor providing both bolt patterns is segmented into two separate adaptors. Each adaptor is thinner and provides a specific bolt pattern interface. This segmentation reduces the offset by distributing the adaptation function across two separate components rather than one thick component that must accommodate both patterns.
Solution Approach 2:
The solution moves from a single-component design to a two-component design, effectively using an additional dimension in the system architecture. This allows each adaptor to be optimized for its specific interface, reducing the overall offset while maintaining both bolt pattern capabilities through the combined system.
