Wheel-Axle Generator Nesting Rotor Stator Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel-axle generators face challenges in being easily attached to vehicle wheels without compromising vehicle stability, as they either protrude from the vehicle body or require shortening of the wheel-axle housing and suspension, leading to instability.
Innovation Solution
A wheel-axle generator design featuring a rotor fixed to a concave portion of the tire wheel and a stator arranged concentrically with the wheel axle, with an arm member extending to the wheel's outer surface to accommodate the stator, allowing for efficient electricity generation without protruding from the vehicle body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the generator is attached without reducing the length of the wheel-axle housing and rear wheel axle, then the generator can be installed without protruding from the vehicle body, but the generator requires a compact design that fits within the existing space
Solution Approach 1:
The generator is nested within the existing wheel-axle housing space by positioning the rotor on the rear wheel axle and the stator on the wheel-axle housing, allowing the generator to fit within the existing structural envelope without protruding from the vehicle body
Solution Approach 2:
The generator components are arranged in a radial configuration around the wheel-axle axis, utilizing the circumferential space within the wheel-axle housing rather than extending axially, thereby achieving compactness in the critical axial dimension
2Shape
If the generator is attached by reducing the length of the wheel-axle housing and rear wheel axle, then the generator can be installed within the existing space, but the running of the vehicle becomes unstable
Solution Approach 1:
The generator components are pre-positioned and secured to the wheel-axle assembly during manufacturing, ensuring proper alignment and structural integrity before vehicle assembly, thereby maintaining vehicle stability without requiring shortening of critical structural components
3Ease of operation
If a generator suitable for the axle is found, then the generator can be easily attached to the wheel-axle portion, but conventionally it has been difficult to find a generator suitable for the axle
Solution Approach 1:
The wheel-axle housing and rear wheel axle are designed to serve dual functions: supporting the wheel assembly and mounting the generator components, thereby creating a universal platform that accommodates both vehicle propulsion and electricity generation functions
Solution Approach 2:
The generator is divided into separate rotor and stator components that can be independently mounted on the wheel-axle assembly, allowing for easier attachment and adaptation to the specific axle configuration without requiring a completely customized integrated design

AI summary
A wheel-axle generator equipped with a rotor configured to rotate with rotation of a wheel and a stator arranged around the rotor. The rotor is fixed to a concave portion that opens toward a vehicle outside of a tire wheel of a wheel. An arm member that has one end attached to a wheel-axle housing or a steering knuckle), that extends so as to stride over a wheel, and that, on a side of an outer surface of the wheel, further extends parallel to the outer surface of the wheel up to a central portion of the wheel. The stator is annularly arranged so as to surround the rotor and is provided on the other end side of the arm member. This arrangement provides space for accommodating a generator without shortening a wheel axle etc. and attaching the generator easily.
