Composite Wheel Rim Post-Forming Threaded Hole Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing composite material wheel rims require diverse reinforcement members with pre-formed threaded holes, leading to increased inventory costs, high product defect rates due to incorrect assembly, and limited compatibility with different wheel hub types, resulting in inefficient production and storage management.
Innovation Solution
A method where inner lining chunks without pre-drilled threaded holes are integrated into the wheel rim, allowing for drilling and tapping of holes post-formation to match the specific spoke count and angle of the requested wheel hub, enabling the wheel rim to fit various hub types and reducing inventory needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If reinforcement members with pre-formed threaded holes are used, then the wheel rim can be assembled with spokes, but the inventory cost increases due to diverse reinforcement members with various angles
Solution Approach 1:
The wheel rim is divided into two separate parts: the rim body and the inner lining chunks. The rim body is manufactured once and can be used for multiple hub types, while the inner lining chunks are separately configured with threaded holes at different angles and positions according to specific hub requirements. This segmentation allows the rim body to be standardized and reused, reducing inventory costs while maintaining assembly capability.
Solution Approach 2:
The rim body is designed as a universal component that can accommodate different types of wheel hubs. By making the rim body compatible with multiple hub types and using interchangeable inner lining chunks, the same rim body can serve multiple functions and be used with different spoke configurations, thereby reducing the need to maintain separate inventories for different wheel rim types.
2Ease of manufacture
If reinforcement members with pre-formed threaded holes are used, then the wheel rim can be assembled with spokes, but the product defect rate increases due to incorrect assembly
Solution Approach 1:
The inner lining chunks are pre-configured with threaded holes at the correct angles and positions before being installed in the wheel rim. This preliminary preparation ensures that when the chunks are installed, the threaded holes are already oriented correctly for the specific hub type, eliminating assembly errors and reducing product defect rates.
Solution Approach 2:
The inner lining chunks act as intermediary components between the rim body and the spokes. These chunks contain the threaded holes and can be selectively installed to match different hub configurations. By using this intermediary layer, the correct alignment and orientation are ensured without requiring direct integration of multiple threaded hole configurations into the rim body itself.
3Ease of manufacture
If the wheel rim is formed with fixed threaded holes, then it can connect spokes, but it cannot fit different types of wheel hubs
Solution Approach 1:
The wheel rim system becomes dynamic and adaptable through the use of interchangeable inner lining chunks. Instead of having fixed threaded holes in the rim body, the system allows for different inner lining chunks to be installed depending on the hub type required. This dynamic configuration enables the same rim body to adapt to different hub types and spoke arrangements.
Solution Approach 2:
The rim body is designed as a universal component that can accommodate different types of wheel hubs. By making the rim body compatible with multiple hub types and using interchangeable inner lining chunks, the same rim body can serve multiple functions and be used with different spoke configurations, thereby reducing the need to maintain separate inventories for different wheel rim types.

AI summary
A method for making the composite material wheel rim includes the steps of: configuring a plurality of inner lining chunks individually to the desired position where the spokes are to be mounted to allow the inner lining chunks to be integrated with an inner annular portion of the wheel rim, next, integrating the formed inner annular portion with an outer annular portion of the wheel rim to form a semi-finished wheel rim, and then, creating the requested threaded holes for connecting the spokes in the inner lining chunks of the inner surface of the semi-finished wheel rim subject to the requested amount and angles of the spokes. By the present method, the semi-finished wheel rim allows drilled, threaded holes subject to needs to fit different types of wheel hub units to increase the yield rate and reduce the inventory of the wheel rims.
