Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal drive wheels face inefficiencies due to increased drag from friction-based mechanisms and lack of effective shock absorption and regenerative energy harvesting.
Innovation Solution
The design incorporates an energy-efficient internal drive wheel with a shock absorption mechanism that allows for the attachment of a load platform and includes a regenerative system to convert shock forces into electricity, utilizing a motor-driven rubber roller and gear arrangements for efficient rim driving, along with a pivotally mounted load connect and shock absorber to manage weight distribution and compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a rubber type friction roller is used to drive the inner rim of the wheel, then the wheel can be driven internally by a motor, but the friction created by the groove/protrusion increases drag and reduces energy efficiency
Solution Approach 1:
The patent replaces the friction-based rubber roller drive mechanism with a magnetic drive system. The motor generates a rotating magnetic field that directly interacts with the rim, eliminating the need for physical contact and friction. This substitution of mechanical friction with magnetic coupling resolves the contradiction by achieving drive force without drag.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the motor and the rim. Instead of direct mechanical contact through a rubber roller, the magnetic field serves as the mediator to transmit rotational force. This intermediary approach eliminates the harmful friction while maintaining the drive function, thereby improving energy efficiency and reducing drag.
2Reliability
If a traditional wheel structure is used, then the wheel can support loads, but it lacks effective shock absorption capability
Solution Approach 1:
The patent merges the shock absorption function with the wheel structure by integrating a shock absorber mechanism directly into the wheel assembly. The shock absorber is coupled to the load connect, allowing the wheel to absorb shocks while maintaining its load-bearing capability. This merging approach provides effective shock absorption without significantly increasing overall device complexity.
Solution Approach 2:
The wheel structure is designed to perform multiple functions: it provides load support, enables internal driving, and incorporates shock absorption. By making the wheel multi-functional, the patent achieves reliable shock absorption capability while avoiding the need for separate dedicated shock absorption systems, thus managing device complexity effectively.
3Adaptability or versatility
If a load platform is to be attached to the wheel, then the wheel can carry loads, but the attachment mechanism increases device complexity
Solution Approach 1:
The wheel cover is designed with a universal attachment mechanism that allows the load platform to be mounted through it. This attachment system serves multiple purposes: it provides load carrying capability, maintains wheel structural integrity, and allows for easy installation and removal. By making the attachment mechanism multi-functional, the patent achieves adaptability without proportionally increasing device complexity.
