Lever-Triggered Self-Powered Structure for Stable Suspended Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-powered devices face inconsistent power generation due to the restriction of their vibration structure by the bottom or top shell, affecting the consistency of power supply when used in different environments or orientations.
Innovation Solution
A self-powered device design featuring a triggering structure with a first lever structure and a self-generation structure, where the first power part receives an external force to rotate and suspend the self-generation structure, allowing it to generate electrical energy in a suspended state, thereby avoiding the restriction caused by the shell and enhancing efficiency and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the self-generation structure is arranged on the bottom shell or top shell, then the device structure is simplified, but the power generation consistency deteriorates due to restriction by the shell
Solution Approach 1:
The patent introduces a first lever structure as an intermediary between the external force and the self-generation structure. The first lever structure includes a first support part and a first triggering member with a first power part, first resistance part, and first connection part. The first connection part is rotatably connected to the first support part to form a first revolute, allowing the self-generation structure to be triggered in a suspended state rather than being directly mounted on the shell, thus eliminating the restriction while maintaining structural simplicity
Solution Approach 2:
The patent changes the mounting dimension of the self-generation structure from being fixed on the bottom or top shell surface to being suspended in the three-dimensional space within the mounting cavity. This dimensional change allows the self-generation structure to operate freely without shell restriction, improving power generation consistency while the lever structure provides the necessary mechanical linkage
2Volume of moving object
If the vibration structure is restricted by the bottom shell or top shell, then the device can be compactly designed, but the power generation efficiency deteriorates due to restricted vibration
Solution Approach 1:
The first lever structure acts as a mediator that transmits external force to the self-generation structure without requiring direct contact with the restrictive shell surfaces. The rotatable connection at the first revolute allows for greater vibration amplitude and freedom of movement, maintaining compact device volume while improving power generation efficiency through unrestricted vibration
Solution Approach 2:
The patent employs a dynamic triggering mechanism where the first lever structure can rotate around the first revolute, allowing the self-generation structure to move dynamically in response to external force rather than being statically restricted. This dynamic capability enables more effective vibration and energy generation within the compact device volume

AI summary
A self-powered device which includes a first lever structure, the first level structure includes: a first support part and a first triggering member, the first triggering member includes a first power part, a first resistance part and a first connection part, the first connection part is rotatably connected to the first support part to form a first revolute; and a self-powered structure arranged on the first resistance part. When the first power part is driven by an external force to rotate around an axis of the first revolute and towards a side of the first support part, the first resistance part is rotated around the axis of the first revolute in an opposite direction of the rotation direction of the first support part, such that the self-generation structure is triggered in a suspended state and generates electrical energy.
