Solution Overview
Problem
Traditional smart rice cookers have a poor cleaning effect during the automatic rice washing process, as they only spray water from a fixed position, leading to inadequate removal of rice residue.
Innovation Solution
A material cleaning method that involves a transportation device with a telescopic assembly and a transportation port, which moves within the accommodation cavity to blow air and stir the material, ensuring the air blows from different positions to enhance cleaning, and includes a mechanism to adjust the telescopic distance and air-blowing frequency based on the amount of grain, simulating hand-washing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If water is sprayed from a fixed position during rice washing, then the device structure is simple, but the cleaning effect is poor
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed spray nozzle into a movable transportation port that can move within the accommodation cavity. The transportation device with telescopic assembly enables the nozzle to dynamically adjust its position and move through the material, converting static water spraying into dynamic airflow-based material movement and mixing, thereby significantly improving the cleaning effect
Solution Approach 2:
The patent employs pneumatics by using air blowing through the transportation port to achieve material cleaning. Instead of relying solely on water spraying, the system introduces airflow to tumble and mix the rice material, utilizing pneumatic forces to enhance the cleaning process and remove rice residue more effectively
2Manufacturing precision
If the transportation port moves in the material to blow air from different positions, then the cleaning effect is enhanced, but the device complexity increases
Solution Approach 1:
The transportation device serves multiple functions: it acts as both a material transportation mechanism and a cleaning device. The telescopic assembly enables the transportation port to reach different positions within the accommodation cavity, allowing a single device to perform both material handling and thorough cleaning operations, thereby justifying the increased structural complexity through multi-functionality
3Adaptability or versatility
If the telescopic assembly adjusts the transportation port position based on grain amount, then the cleaning adaptability improves, but the control complexity increases
Solution Approach 1:
The system implements feedback control by detecting the amount of grain in the accommodation cavity and automatically adjusting the telescopic assembly's extension distance and the air-blowing frequency accordingly. This closed-loop control ensures optimal cleaning performance for different grain quantities, enhancing adaptability while managing control complexity through automated feedback mechanisms
