Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manual air pumps lack a reminder function to indicate when air extraction is completed, leading to potential labor waste and compromised sealed storage effects.
Innovation Solution
An air pump equipped with a push rod assembly, air pressure sensor, and reminding mechanism that alerts the user when the air extraction is finished, using components like a light emitting diode, sounder, or vibration motor to signal completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a manual air pump is used without a reminder function, then the device complexity is low, but the operator cannot know the air extraction state leading to labor waste
Solution Approach 1:
The patent applies feedback by introducing an air pressure sensor that continuously monitors the air pressure in the container and a reminding mechanism that provides real-time feedback to the operator. When the air pressure reaches a preset threshold indicating complete air extraction, the reminding mechanism activates to notify the operator, thus eliminating information loss about the extraction state.
Solution Approach 2:
The patent replaces the purely mechanical manual air pump with an integrated system that incorporates electronic sensing and reminding components. The air pressure sensor and reminding mechanism transform the mechanical air extraction process into a smart system that provides automated information feedback, resolving the contradiction between simplicity and information awareness.
2Reliability
If the air extraction is stopped before complete, then the device complexity remains low, but the sealed storage effect is influenced
Solution Approach 1:
The air pressure sensor provides continuous feedback on the air pressure status, and the reminding mechanism ensures the operator is notified when extraction is complete. This feedback loop guarantees that the operator can stop extraction at the optimal point to achieve reliable sealed storage effect without under-extraction.
Solution Approach 2:
The system performs preliminary monitoring of air pressure throughout the extraction process and prepares the reminding function in advance. When the preset pressure threshold is reached, the reminder activates promptly, ensuring the operator can immediately stop extraction to maintain optimal sealed storage effect.
3Productivity
If the air extraction continues after complete, then the device complexity remains low, but labor waste occurs
Solution Approach 1:
The air pressure sensor and reminding mechanism provide real-time feedback to the operator, enabling immediate cessation of extraction when complete. This prevents unnecessary continued operation, eliminates labor waste, and improves operational efficiency by ensuring extraction stops exactly when needed.
Solution Approach 2:
The system performs self-monitoring and self-notification, automatically detecting when extraction is complete and informing the operator without requiring manual checking. This self-service capability eliminates time loss and improves productivity by preventing over-extraction.
