Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport devices with integrated energy generators are prone to damage from the transported objects or persons, and the positioning of these generators reduces the capacity for carrying objects or persons, particularly the standing area for a person.
Innovation Solution
A transport device with a drive element comprising two or more drive magnets and an output element with fewer magnets, utilizing a non-magnetic shielding element to alter the magnetic field, which allows for the generation of electric current without exposing the energy-generating components to damage and optimizes space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the energy generator is integrated into the transport device, then electric energy can be generated, but the generator is exposed to damage by the transported object or person and the standing area is reduced
Solution Approach 1:
The energy generation system is segmented into separate functional components: drive magnets attached to the rolling device, output magnets on a rotatable output element, and stator windings in a stationary housing. This segmentation allows the generator components to be distributed throughout the transport device structure rather than concentrated in one vulnerable location, protecting them from damage while maintaining energy generation capability.
Solution Approach 2:
The energy generation components are nested within the existing structural elements of the transport device. The drive magnets are integrated into the rolling device, the output element is nested within the housing, and the stator windings are positioned within the housing structure. This nesting utilizes the existing structural framework to protect and house the generator components without requiring additional external structures that would reduce standing area.
2Use of energy by moving object
If the energy generator is integrated into the transport device, then electric energy can be generated, but the standing area for transporting a person is reduced
Solution Approach 1:
The housing structure serves multiple functions: it provides the structural framework of the transport device, houses the stator windings for energy generation, and defines the standing area boundaries. By making the housing multi-functional, the design eliminates the need for separate dedicated spaces for energy generation components, thereby maximizing the standing area while maintaining full energy generation capability.
Solution Approach 2:
The energy generation system utilizes the vertical and radial dimensions of the rolling device and housing structure rather than occupying horizontal floor space. Drive magnets are positioned on the rolling device circumference, output magnets are arranged radially on the output element, and stator windings are positioned vertically within the housing. This dimensional arrangement generates energy without encroaching on the horizontal standing area.
3Use of energy by moving object
If traditional generator components are used, then electric current can be generated, but mechanical friction increases and efficiency decreases
Solution Approach 1:
The traditional mechanical generator system with physical contact between rotating and stationary components is replaced with a magnetic field-based system. Drive magnets on the rolling device create a rotating magnetic field that interacts with output magnets on the output element through magnetic attraction and repulsion forces, eliminating the need for mechanical bearings, shafts, and direct physical contact. This substitution dramatically reduces mechanical friction and energy loss while maintaining efficient electric current generation.
