Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional parking lock actuation unit is used, then the basic locking function is achieved, but precise control adjustment options and flexibility for various installation situations are lacking
Solution Approach 1:
The actuating body is designed with a universal adapter device that can accommodate different deflection mechanism connection variants. The adapter device includes a connecting section with standardized interfaces that can connect to various deflection mechanism types, allowing the same actuating body to be used across different installation situations and structural environments without requiring custom designs for each application.
Solution Approach 2:
The adjusting member is designed with translational movement capability along its longitudinal axis, driven by a drive unit with adjustable control. The position sensor provides real-time feedback enabling dynamic adjustment of the adjusting member's position, allowing precise control adaptation to different installation requirements while maintaining a relatively simple base structure.
2Manufacturing precision
If the adjusting member is made fixed and simple, then the device complexity is reduced, but precise control and quick adjustments cannot be achieved
Solution Approach 1:
A position sensor is integrated into the actuating body to detect the position of the adjusting member along its longitudinal axis. The sensor provides feedback signals to a control unit, enabling closed-loop control of the drive unit. This allows precise positioning of the adjusting member while keeping the mechanical structure relatively simple, as the precision is achieved through electronic control rather than complex mechanical mechanisms.
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with a drive unit that uses motorized actuation combined with position sensing and electronic control. Instead of using multiple mechanical linkages, gears, or cam mechanisms to achieve precise adjustment, the system uses a controlled linear actuator with feedback control, substituting mechanical complexity with electromechanical control.
3Ease of manufacture
If a standardized actuation unit is used, then ease of manufacture is improved, but adaptability to different installation situations deteriorates
Solution Approach 1:
The actuation unit is segmented into modular components: a standardized actuating body containing the drive unit and position sensor, and interchangeable adapter devices that can be selected based on the specific installation requirements. This segmentation allows the main actuating body to be manufactured in standard quantities, while only the adapter section needs to be varied for different applications, combining the benefits of standardized production with installation flexibility.
