Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual suction lifter is used to carry large objects or perform aloft work, then the initial suction strength is sufficient to adsorb the object, but the suction strength decreases over time leading to potential detachment and safety hazards
Solution Approach 1:
The patent implements a feedback control system where a pressure sensor continuously monitors the suction pressure inside the sealed space and sends signals to the control unit. When the pressure indicates reduced suction strength, the control unit automatically activates the vacuum pump to restore the required negative pressure, ensuring consistent adhesion throughout the operation duration.
Solution Approach 2:
The suction lifter performs self-adjustment of suction strength through the automated control system. The control unit independently monitors pressure conditions and activates the vacuum pump as needed without requiring manual intervention, enabling the device to maintain optimal suction strength autonomously throughout extended operation periods.
2Productivity
If the suction lifter operates continuously without adjustment, then productivity is maintained, but safety risks increase due to potential detachment from glass
Solution Approach 1:
The pressure sensor provides continuous feedback on the adhesion status by monitoring pressure changes in the sealed space. This real-time monitoring enables the control unit to detect early signs of adhesion loss and immediately activate the vacuum pump to restore suction strength, maintaining both continuous operation and high adhesion reliability throughout the work process.
3Reliability
If the vacuum pump operates continuously to maintain suction strength, then adhesion reliability is improved, but energy consumption increases
Solution Approach 1:
The vacuum pump operates periodically rather than continuously, activating only when the pressure sensor detects that suction strength has dropped below the required threshold. The control unit manages on-demand operation cycles, allowing the pump to run intermittently to maintain adhesion reliability while significantly reducing overall energy consumption compared to continuous operation.

AI summary
A touch display device includes a display module, a touch module and a light-transmitting substrate. The display module has a display surface and a bottom surface opposite to the display surface. The touch module is fixed to the display surface by an adhesive. The adhesive, the touch module and the display surface together form an accommodating space between the display module and the touch module. The light-transmitting substrate is disposed in the accommodating space, one side of the light-transmitting substrate is fixed to the display surface by a first optical adhesive, the other side of the light-transmitting substrate is fixed to the touch module by a second optical adhesive. An adhesive strength of the adhesive is greater than an adhesive strength of the first optical adhesive, and the adhesive strength of the adhesive is greater than an adhesive strength of the second optical adhesive.
