Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional shock absorber hard points are fixed and require disassembly for height adjustment, then structural stability is maintained, but operational convenience deteriorates and work quantity increases
Solution Approach 1:
The shock absorber hard point connection structure is transformed from a fixed static connection to a dynamically adjustable connection. The connection end can rotate relative to the receiving recess through the electromagnetic adjustment mechanism, allowing the hard point position to change dynamically without disassembly, thereby improving ease of operation while maintaining structural integrity during normal operation.
Solution Approach 2:
The traditional mechanical adjustment method requiring disassembly and manual repositioning of hard points is replaced with an electromagnetic adjustment mechanism. The electromagnetic cooperation between stator and rotor enables automated rotation of the connection end, substituting complex manual mechanical operations with a controlled electromagnetic system that simplifies the adjustment process.
2Productivity
If shock absorber length is adjusted by disassembling and repositioning hard points, then length adjustment is achieved, but time consumption and labor intensity increase
Solution Approach 1:
The connection end is pre-configured with threaded grooves and engagement structures that enable rapid rotational adjustment. The receiving recess is pre-formed with corresponding geometric features and guide structures. This preliminary preparation allows the connection end to be quickly rotated to different positions without time-consuming disassembly and reassembly operations, significantly reducing adjustment time and improving productivity.
Solution Approach 2:
The electromagnetic adjustment mechanism enables the shock absorber to perform its own length adjustment without requiring external disassembly operations. The connection end rotates automatically under electromagnetic actuation, allowing the device to adjust itself to the required length, thereby eliminating labor-intensive manual operations and reducing adjustment time.
3Adaptability or versatility
If electromagnetic adjustment mechanism is added to enable rotation without disassembly, then operational convenience improves, but device complexity increases
Solution Approach 1:
The electromagnetic adjustment mechanism serves multiple functions: it enables rotation of the connection end, adjusts the shock absorber length, and maintains structural stability during adjustment. The threaded engagement between the connection end and rotor provides both positioning and driving functions. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving high adaptability.
Solution Approach 2:
The rotor is disposed within the receiving recess, and the connection end is disposed within the rotor, creating a nested structure. The stator is fixed within the receiving recess, forming another nested arrangement. This nesting minimizes the space required for the adjustment mechanism and reduces the overall structural complexity while enabling the electromagnetic adjustment function.
