Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pumps or hand-held vacuum pumps are used for vacuum extraction, then vacuum extraction can be achieved, but the operation is inconvenient and drain performance is poor
Solution Approach 1:
The patent replaces manual mechanical pumping operations with an automated electronic control system that includes a microcontroller, solenoid valves, and automated sequencing logic. The control circuit board automatically manages the vacuum extraction process through electronic control of the vacuum pump and associated valves, eliminating the need for manual operation while maintaining or improving drain performance through optimized extraction sequences and automated monitoring.
2Reliability
If threaded caps are used for sealing Mason bottles, then sealing effect is achieved, but air inside the bottles cannot be discharged
Solution Approach 1:
The cap assembly is divided into separate functional components: a sealing element (such as a gasket or sealing ring) that provides the sealing function, and a valve mechanism (including solenoid valves and flow channels) that provides the air discharge function. This segmentation allows the sealing cap to simultaneously achieve both reliable sealing and effective air discharge during the vacuum extraction process, as the valve mechanism can open to allow air removal while the sealing element maintains the seal.
Solution Approach 2:
The cap incorporates dynamic valve mechanisms that can transition between different states (open/closed, sealed/ventilated) based on the extraction phase. During the extraction phase, valves open to allow air discharge while maintaining sealing integrity. During the sealing phase, valves close to maintain the vacuum seal. This dynamic behavior allows the same cap structure to fulfill both contradictory requirements at different times in the process cycle.
3Extent of automation
If automatic vacuum extraction products are used, then automation is achieved, but drain performance is poor and internal components are liable to damage
Solution Approach 1:
The patent incorporates protective measures in advance to prevent component damage during automated operation. This includes pressure sensors and control logic that monitor vacuum levels and prevent excessive pressure differentials that could damage the bottle or cap components. The system also includes controlled ramp-up and ramp-down sequences that gradually change pressure conditions, avoiding sudden pressure shocks that could damage internal components. These preemptive protective measures allow aggressive vacuum extraction to be performed safely without compromising component durability.
Solution Approach 2:
The automated system incorporates sensors (such as pressure sensors, flow sensors, or position sensors) that provide real-time feedback to the control circuit board. This feedback allows the system to monitor the extraction process, detect abnormal conditions (such as blocked drains, excessive pressure, or component malfunctions), and automatically adjust operation or alert the user. This closed-loop control prevents component damage by detecting and correcting potential problems before they cause failure, while maintaining high automation levels.
4Productivity
If existing vacuum extraction equipment is used, then vacuum extraction function is provided, but universality is poor
Solution Approach 1:
The patent designs the vacuum extraction device with universal interfaces and modular components that can accommodate different bottle sizes, shapes, and types. The cap assembly includes adjustable sealing elements, universal connection interfaces, and adaptable valve configurations that work with various container formats. The control system is programmed to recognize and adapt to different container types, allowing a single device to perform vacuum extraction across multiple applications (bottles, jars, bags, boxes) without requiring dedicated equipment for each container type, thereby achieving both effective extraction and broad universality.
