Bicycle Rim Single-Point Reinforcing Structure for Weight Reduction

The patent applies local quality by varying the wall thickness of the rim body: the first wall thickness is greater than the second wall thickness. Specifically, regions requiring higher strength (such as areas near spoke holes or high-stress zones) have increased wall thickness, while other regions maintain thinner walls to reduce overall weight. This localized thickness variation optimizes the strength-to-weight ratio by concentrating material only where structurally necessary.

The rim body is segmented into multiple wall regions with different thickness characteristics. The structure divides the rim into at least two distinct wall sections: a first wall with greater thickness for load-bearing functions, and a second wall with lesser thickness for weight reduction. This segmentation allows independent optimization of different rim zones based on their specific mechanical requirements.

Instead of adding complex reinforcing mechanisms throughout the rim, the patent uses local quality by simply varying wall thickness in specific regions. The rim body contains multiple wall sections with different thicknesses, where thicker sections provide enhanced strength locally without requiring additional components, fasteners, or complex structural elements. This approach maintains structural simplicity while achieving the desired load-bearing capacity.

The patent extracts unnecessary reinforcing mechanisms from the traditional rim design. By removing complex reinforcements and replacing them with a simplified variable thickness structure, the design eliminates redundant components while maintaining or improving strength. The solution takes out the complexity of traditional reinforcing methods and retains only the essential thickness variation needed for load-bearing.
