Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of wiring for power supply in food processors due to the need for electrical connections between the main unit and bowl assembly complicates the design and increases costs, particularly because existing solutions require isolated power circuits for safety reasons.
Innovation Solution
A food processor circuit that incorporates a light source, a solar module to convert light energy into electrical energy, and a power receiving circuit, which simplifies the wiring layout by eliminating the need for direct electrical connections between the main unit and bowl assembly, using optical communication modules to transmit detection signals and reducing the power board area and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If direct electrical connections are used between main unit and bowl assembly, then power supply is achieved, but wiring complexity increases
Solution Approach 1:
The patent replaces direct electrical connections with an optical system consisting of a light source in the main unit and a solar module in the bowl assembly. The light source emits light that is converted to electrical energy by the solar module, eliminating the need for physical electrical wires between the two components. This substitution of mechanical/electrical connection with an optical energy transfer mechanism directly resolves the wiring complexity issue while maintaining power supply functionality.
2Reliability
If isolated power circuits are implemented for safety, then safety requirements are met, but power board area and cost increase
Solution Approach 1:
The patent extracts the power conversion function from the main unit's power board and relocates it to the bowl assembly through the solar module. The solar module independently converts light energy to electrical energy at the point of use, eliminating the need for complex isolated power circuits on the power board. This extraction of the power conversion function reduces the power board area while maintaining safety through optical isolation.
