Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a simple container device is used, then the device structure is simple and easy to manufacture, but the liquid output control is unstable and inaccurate
Solution Approach 1:
The container is divided into multiple functional cavities: an accommodating cavity for receiving liquid, a first liquid storage cavity for storing liquid under normal pressure, and a second liquid storage cavity for storing liquid under low pressure. This segmentation allows different regions to perform different functions (storage, discharge, pressure regulation), achieving stable and accurate liquid output control while maintaining a relatively simple overall structure.
2Manufacturing precision
If liquid is discharged freely from the container, then the discharge process is simple and fast, but the liquid quantity cannot be controlled accurately leading to waste or shortage
Solution Approach 1:
The invention utilizes pressure differential mechanisms between the first liquid storage cavity (normal pressure) and the second liquid storage cavity (low pressure) to control liquid discharge. The fluid channel connects these cavities, allowing pressure-driven liquid flow from the second cavity through the fluid channel to the outlet, achieving controlled and accurate liquid quantity discharge while maintaining efficient flow.
3Loss of substance
If the container device lacks liquid recovery mechanism, then the device structure is simple, but liquid waste occurs and product cost increases
Solution Approach 1:
The second liquid storage cavity functions as a recovery mechanism that captures and stores liquid that would otherwise be wasted during the discharge process. By maintaining low pressure in this cavity, it automatically receives and stores excess or returned liquid, preventing loss and enabling potential reuse, thereby reducing liquid waste and product costs while adding only moderate structural complexity.
