Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food processors have complex vacuum pumping structures that are unreliable and increase the risk of ingredient oxidation during stirring, leading to nutrient loss and reduced taste.
Innovation Solution
A simplified vacuum pumping structure where the vacuum pumping device is detachably connected to the cup cover of the food processor, forming a direct pumping air path to the cup body, eliminating the need for a base-mounted vacuum pumping device and reducing the overall complexity and volume of the food processor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vacuum pumping device is mounted on the base with a fixed air path through the guide post or cup body, then the vacuum pumping function is achieved, but the air path becomes too long, the overall structure becomes more complicated, and the reliability during pumping deteriorates
Solution Approach 1:
The vacuum pumping device is segmented from the base structure and integrated into the cup cover, creating an independent pumping module. This segmentation allows the pumping function to be achieved while shortening the air path and simplifying the overall structure by eliminating the need for complex base-mounted guide posts and internal air channels.
Solution Approach 2:
The cup cover acts as an intermediary component that houses the vacuum pumping device and provides a direct air path to the cup body through the pumping opening. This intermediary structure eliminates the need for long air paths through the base and guide posts, thereby improving reliability and reducing complexity.
2Length of moving object
If the vacuum pumping device is mounted on the base, then the pumping function is provided, but the air path is too long causing increased complexity and reduced reliability
Solution Approach 1:
Instead of mounting the pumping device on the base and routing air through the base and guide post, the invention inverts the arrangement by mounting the pumping device on the cup cover and routing air directly through the cup cover opening. This inversion dramatically shortens the air path and simplifies the structure.
3Reliability
If a base-mounted vacuum pumping device with fixed air path is used, then pumping capability is achieved, but the overall structure becomes more complicated and volume increases
Solution Approach 1:
The vacuum pumping device is merged with the cup cover assembly, combining two previously separate functional elements (pumping device and cup cover) into a single integrated unit. This merging reduces the overall volume of the food processor by eliminating the need for separate base-mounted pumping components and complex internal air routing structures.
