Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If mechanical lever mechanisms or springs are used to exert tensile force on the suction cup, then holding force is generated, but the suction cup comes loose with minor changes in ambient conditions
Solution Approach 1:
The patent implements an electronic measuring device that continuously monitors the suction force and provides feedback through a display indicator. This allows real-time detection of suction force changes, enabling the user to adjust the suction cup position or reattach it before complete detachment occurs, thereby preventing the reliability issue caused by ambient condition changes.
Solution Approach 2:
The patent replaces complex mechanical lever mechanisms and spring systems with a simpler direct attachment system. The electronic measuring device and indicator replace the need for mechanical feedback systems, eliminating the complexity and reliability issues associated with mechanical adjustment mechanisms while maintaining adequate holding force.
2Force
If high vacuum is generated in the suction chamber, then holding force is increased, but the suction cup detaches quickly under changing environmental conditions
Solution Approach 1:
The electronic measuring device continuously monitors suction force and provides real-time feedback through the display indicator. This enables the user to detect when environmental changes affect suction performance and make timely adjustments, allowing the system to adapt to varying conditions while maintaining adequate holding force without requiring excessively high vacuum levels.
3Reliability
If manual checking and reassembly of the holder is required, then attachment stability can be verified, but the process requires two hands and realignment
Solution Approach 1:
The patent implements a self-monitoring system where the electronic measuring device automatically detects suction force levels and the display indicator provides continuous visual feedback about attachment status. This eliminates the need for manual checking and reassembly operations, as the system continuously monitors and alerts the user to attachment status without requiring hands-on verification or realignment operations.
Solution Approach 2:
The display indicator provides continuous visual feedback about suction force adequacy, allowing the user to verify attachment status at a glance without manual intervention. This feedback mechanism replaces the need for manual checking and makes the system self-monitoring, significantly improving ease of operation while maintaining reliability verification.
4Force
If the holder is pressed against the working surface for reattachment, then suction force is restored, but assembly difficulties occur
Solution Approach 1:
The electronic measuring device and display indicator provide real-time feedback during the reattachment process, showing when adequate suction force is achieved. This guides the user through the reattachment process, indicating when the holder has been properly positioned and sufficient vacuum established, thereby eliminating assembly difficulties and reducing the effort required for reattachment.
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
Ensures secure attachment of devices like navigation systems by allowing one-handed operation to maintain optimal suction force, adapting to different surfaces and conditions, and providing visual and acoustic feedback for safe functioning.
Implementation Method 1
the vacuum can become too weak to hold the fastened devices
Implementation Method 2
Suction holders that are equipped with the widespread clamping mechanisms
Implementation Method 3
the vacuum breaks down immediately due to the lack of elasticity in the suction cup
Implementation Method 4

AI summary
The device (31) has reference coils (38, 39) measuring suction force, and a color marker indicating the suction force. An actuating head (34) increases the suction force, and a compression spring i.e. helical spring, is pressed against the actuating head that is supported in a sleeve (35). A coil is arranged in the actuating head and the sleeve such that displacement of the actuating head to the sleeve is measured. A pre-tensioning lever fixes the actuating head against force of the helical spring. The actuating head is pressed downward in the sleeve that is fixed at a housing (32).
