Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical buckles or manual locking structures are used, then the clamping device is simple in structure, but the operation becomes cumbersome and complexity increases
Solution Approach 1:
The patent replaces manual mechanical locking structures with an automated electromechanical clamping mechanism. The drive motor drives the lead screw to convert rotational motion into linear motion of the threaded sliding block, which automatically moves the movable clamping plate to clamp the equipment. This substitution eliminates cumbersome manual operations while maintaining structural simplicity through standardized motorized components.
Solution Approach 2:
The clamping device achieves self-service operation through the proximity sensor that automatically detects when equipment is placed on the base and triggers the drive motor to activate the clamping mechanism without manual intervention. The system also includes self-release functionality where the clamping plate automatically releases when equipment is removed, eliminating the need for manual release operations.
2Measurement precision
If traditional sensing solutions like infrared sensors are used, then the sensing system is simple, but detection precision is poor and environmental interference susceptibility increases
Solution Approach 1:
The patent replaces traditional infrared sensors with a proximity sensor that utilizes electromagnetic field detection principles. This proximity sensor is specifically designed to detect metal objects through near-field induction, providing high precision detection of metallic equipment while being immune to environmental factors such as dust, moisture, and ambient light that affect infrared sensors.
3Adaptability or versatility
If a single drive mode is used, then the drive mechanism is simple, but adaptability to different equipment sizes is poor
Solution Approach 1:
The clamping mechanism employs a dynamically adjustable design where the movable clamping plate can move along the lead screw to accommodate different equipment sizes. The drive motor provides variable clamping force through the lead screw mechanism, allowing the same drive system to adapt to small smartphones, medium tablets, and large laptops. The proximity sensor detects the presence and position of equipment to automatically adjust the clamping plate position and force.
Solution Approach 2:
The electromechanical clamping mechanism is designed with universal applicability to clamp various types of electronic equipment including smartphones, tablets, and laptops of different sizes. The proximity sensor and motorized drive work together to provide a single unified clamping action that adapts to multiple device types, eliminating the need for multiple specialized clamping mechanisms.
4Extent of automation
If manual locking structures are used, then the release is convenient, but automatic clamping triggering is difficult to achieve
Solution Approach 1:
The system achieves complete automation through the proximity sensor that automatically detects when equipment is placed on the base and triggers the drive motor to activate the clamping sequence without any manual input. For release, the system provides self-service functionality where removing the equipment automatically triggers the motor to reverse and release the clamping plate, eliminating the need for manual release buttons or switches.
