Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If release lines are separately designed with electronic controls to supply compressed air to the suction pad, then the suction pad can be quickly separated from the object, but the design and structure become complicated, malfunctions increase, and maintenance becomes difficult
Solution Approach 1:
The invention extracts the electronic control system and separate release lines from the vacuum pump design. Instead of using complex electronic-controlled release lines, the patent uses a simple manual valve system that operators can directly control to release compressed air to the suction pad, thereby achieving quick separation while eliminating complicated electronic mechanisms
Solution Approach 2:
The invention replaces electronic control mechanisms with a pneumatic control system. A manual valve is used to control the flow of compressed air through a release line to the suction pad, using pneumatic pressure control instead of electronic control to achieve the same function with simpler mechanics
2Speed
If release lines are separately designed with electronic controls to supply compressed air to the suction pad, then the suction pad can be quickly separated from the object, but maintenance becomes difficult
Solution Approach 1:
The invention removes the electronic control components and complex release line system that make maintenance difficult. By using a simple manual valve and direct pneumatic connection to supply compressed air to the suction pad, the system becomes much easier to maintain while preserving the quick separation capability
3Ease of operation
If compressed air is supplied to release the vacuum in the suction pad, then the suction pad separates from the object, but the object may be damaged by strokes applied during release
Solution Approach 1:
The invention introduces a controllable dynamic system for vacuum release. Instead of immediate or fixed-rate release, the manual valve allows operators to dynamically control the rate at which compressed air is supplied to the suction pad, enabling gradual or controlled release that prevents sudden strokes while maintaining separation capability
Solution Approach 2:
The invention enables control over the release parameter (air supply rate) to the suction pad. By adjusting the manual valve, operators can change the flow rate of compressed air, thereby controlling the pressure build-up rate and preventing excessive strokes that could damage objects while still achieving effective separation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies the operation, reduces malfunctions, enables quick and uniform vacuum release, and allows for adjustable stroke, while naturally cleaning the filter material without manual intervention.
Implementation Method 1
when compressed air is supplied through the inlet and passes through and is ejected from the nozzles at a high speed, the inner space is evacuated, thereby creating the vacuum or negative pressure
Implementation Method 2
a skirt-type check valve which is to be moved up and down by air pressure to open and close the upper portion of the support tube
Implementation Method 3
a filter material disposed between the suction port and the support tube. The filter material filters discharge air that is introduced by allowing the discharge air to pass through upward when the pump part operates
Implementation Method 4
At the moment that the supply of the compressed air is stopped, the air inside the pressure chamber flows backward, thereby moving the check valve, whereby the vacuum is released
Data Source
AI summary
A quick-release vacuum pump which is mainly applied to a vacuum transport system. The vacuum pump has a mechanism in which part of compressed air supplied for generating a vacuum state is stored firstly in a chamber, and then the vacuum state within the chamber is released when transportation is completed. When the vacuum state is released, a check valve is moved by the pressure of air that flows backward. The range of movement of the check valve is adjusted by a control means. An air filter is disposed at the lower end of the check valve. The release of the vacuum state is quick and controllable. Also, the filter is naturally filtered and cleaned.
