Axle Wrap Overlap Design Eliminates Backing Strips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing axle suspension systems require additional components like backing strips and ceramic tape to accommodate axle diameter variations, increasing manufacturing complexity and cost, and reducing the strength of the axle wrap due to the need for grooves and recesses for these components.
Innovation Solution
An axle suspension system with an overlapping axle wrap design that eliminates the need for backing strips by using a weld seam on the outer surface to couple overlapping end portions, allowing the axle wrap to compress securely around the axle without engaging the axle, thus eliminating the need for additional components and enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional components like backing strips and ceramic tape are used to accommodate axle diameter variations, then the axle wrap can be manufactured, but manufacturing complexity and cost increase
Solution Approach 1:
The patent removes the backing strip and ceramic tape components from the traditional axle wrap design. By eliminating these separate components, the design achieves adaptability to axle diameter variations through the overlapping wrap structure itself, thereby reducing manufacturing complexity and the number of parts required
Solution Approach 2:
The patent combines the functions of the wrap, backing strip, and ceramic tape into a single integrated overlapping wrap structure. The overlap region itself provides the accommodation for diameter variations, merging multiple components into one and simplifying the manufacturing process
2Adaptability or versatility
If additional components like backing strips and ceramic tape are used to accommodate axle diameter variations, then the axle wrap can be manufactured, but manufacturing cost increases
Solution Approach 1:
The patent eliminates the backing strip and ceramic tape components, reducing the bill of materials and assembly steps. This extraction of unnecessary components directly reduces manufacturing cost while maintaining the ability to accommodate axle diameter variations through the overlapping design
Solution Approach 2:
The patent uses a simple overlapping wrap structure that can be manufactured more economically than traditional designs requiring precision-machined backing strips and ceramic tape. The overlapping design tolerates diameter variations without requiring expensive precision components
3Adaptability or versatility
If grooves and recesses are created for backing strips, then the axle wrap can accommodate additional components, but the strength of the axle wrap is reduced
Solution Approach 1:
The patent removes the backing strip and ceramic tape components that required grooves and recesses. By eliminating these components, the design removes the need for weakening grooves and recesses, thereby maintaining the full strength of the wrap structure while still accommodating axle diameter variations through the overlap
Solution Approach 2:
The patent merges the accommodation function into the wrap structure itself through overlapping, eliminating the need for separate components and their associated grooves. This integration maintains structural integrity by avoiding the strength-reducing features required for separate components
4Strength
If weld seam engages the axle, then the axle wrap is securely coupled, but the axle surface is compromised
Solution Approach 1:
The patent uses the overlapping wrap structure as an intermediary that provides coupling strength without direct weld contact with the axle. The overlap region acts as a mediator that transfers and distributes forces, allowing secure coupling while protecting the axle surface from weld damage
Solution Approach 2:
The patent employs a sacrificial overlap region that absorbs the welding process and protects the axle. The overlap area serves as a disposable element that can be welded without concern for axle surface integrity, as it is not critical to the overall function
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design reduces manufacturing costs and complexity by eliminating the need for additional components, maintains structural integrity by allowing full-thickness weld seams, and accommodates axle diameter variations without compromising strength.
Implementation Method 1
The weld seam may fixedly couple the second end portion to the first end portion. The weld seam may be provided on the outer surface and may not engage the axle.

AI summary
An axle suspension system and a method of manufacture. The axle suspension system may have an axle, an axle wrap, and a weld seam. The axle wrap may receive the axle and may have a first end portion and a second end portion that overlaps the first end portion. A weld seam may couple the first end portion to the second end portion.
