Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices with rotary mechanisms, such as pet leashes and bicycles, require both rotation-induced and shake-induced power generation, but existing solutions occupy large space and increase weight due to separate structures for each type of power generation, compromising convenience.
Innovation Solution
A co-constructed power generation device that integrates both shake-induced and rotation-induced power generation using a single electromagnetic coil and magnetic body, with elastic members to facilitate relative movement between the magnetic body and coil, allowing for simultaneous power generation from both sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate structures for rotation-induced power generation and shake-induced power generation are individually disposed in a device with a rotary mechanism, then both power generation functions can be achieved, but the device occupies large space and greatly increases weight, reducing usage convenience
Solution Approach 1:
The patent combines rotation-induced power generation and shake-induced power generation into a single integrated structure. The electromagnetic coil serves dual purposes: it generates power through rotation-induced electromagnetic induction when the coil rotates with the rotary mechanism, and through shake-induced electromagnetic induction when the magnetic body moves relative to the coil during shaking. This merging of functions eliminates the need for separate power generation structures, significantly reducing device weight while maintaining both power generation capabilities
Solution Approach 2:
The electromagnetic coil and magnetic body assembly is designed to perform multiple functions: it generates electrical energy through both rotation-induced electromagnetic induction (when the coil rotates with the rotary mechanism) and shake-induced electromagnetic induction (when the magnetic body moves relative to the coil during shaking). This multi-functional design allows a single structure to replace what would traditionally require separate dedicated structures for each power generation mode
2Adaptability or versatility
If separate structures for rotation-induced power generation and shake-induced power generation are individually disposed in a device with a rotary mechanism, then both power generation functions can be achieved, but the device occupies large space, reducing usage convenience
Solution Approach 1:
The patent merges rotation-induced power generation and shake-induced power generation into a single compact structure. The electromagnetic coil and magnetic body are positioned such that the same components enable both power generation modes: rotation-induced electromagnetic induction occurs when the coil rotates with the rotary mechanism, while shake-induced electromagnetic induction occurs when the magnetic body moves relative to the coil during shaking. This integration dramatically reduces the space required compared to having separate structures for each function
Solution Approach 2:
The patent employs a nested arrangement where the magnetic body is disposed within the electromagnetic coil. This nesting allows the shake-induced power generation components to be contained within the rotation-induced power generation structure, maximizing space utilization. The magnetic body can move freely within the coil during shaking while the coil itself rotates during rotation-induced power generation, enabling both functions in a compact nested configuration
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
The integrated solution reduces the overall size and weight of the device while maintaining high power generation efficiency in both modes, enhancing convenience and reducing the need for separate power generation structures.
Implementation Method 1
The principle of magnetoelectricity is that when a conductor cuts magnetic field lines, electromagnetic induction phenomenon occurs on the conductor so as to generate an induced current
