Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction bodies for cleaners require external electrical connections, complicating manufacturing and increasing the risk of wire malfunctions, which can prevent additional devices from functioning due to the separation of the cleaner body and suction body.
Innovation Solution
The suction body incorporates a generator that converts rotary energy from a fan into electric energy, powering integrated devices such as an ultraviolet sterilizer, lighting device, and displaying device, eliminating the need for external electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wires are used to connect the cleaner body with the suction body, then electric energy can be supplied to additional devices, but the manufacturing process becomes complicated and wire malfunctions may occur
Solution Approach 1:
The patent extracts the power generation function from the cleaner body and relocates it to the suction body. A generator is installed in the suction body to convert the kinetic energy of drawn-in air directly into electrical energy, eliminating the need for complex wiring between the cleaner body and suction body while maintaining power supply capability for additional devices
Solution Approach 2:
The suction body becomes self-sufficient by generating its own electrical energy through the generator powered by the kinetic energy of drawn-in air. This self-service approach eliminates dependence on external wiring for power supply, simplifying the manufacturing process while enabling additional devices to function
2Use of energy by moving object
If wires are used to connect the cleaner body with the suction body, then electric energy can be supplied to additional devices, but wire malfunctions may occur due to the flexible connection hose
Solution Approach 1:
The patent removes the vulnerable wire connection from the system by extracting the power generation function to the suction body. The generator converts kinetic energy of drawn-in air into electrical energy locally, eliminating the flexible connection hose and wire assembly that were prone to malfunction
Solution Approach 2:
The suction body generates its own electrical power through the generator, making it self-sufficient and independent of external wire connections. This eliminates the reliability issues associated with wires passing through flexible connection hoses
