Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If solid steel mounting plate holders are used to withstand high loads, then load-bearing capacity is improved, but manufacturing cost and handling difficulty increase
Solution Approach 1:
The mounting plate holder is divided into two separate components: a mounting bracket and a bearing piece. The bearing piece can be pre-assembled on the mounting plate, allowing the mounting plate to be placed on the mounting bracket via the bearing piece. This segmentation simplifies assembly and handling while maintaining load-bearing capacity.
Solution Approach 2:
A damping element is introduced as an intermediary component between the bearing piece and the mounting bracket. This damping element absorbs vibrations and reduces mechanical stress, allowing the use of lighter, more cost-effective materials while maintaining sufficient strength under dynamic conditions.
2Stability of the object's composition
If rigid mounting plate holders are used, then structural stability is improved, but vibration-induced torsion and wear increase
Solution Approach 1:
The damping element is positioned between the bearing piece and the mounting bracket to provide beforehand cushioning against vibrations. This cushioning effect absorbs vibration energy before it can cause torsion or wear in the rigid mounting structure, protecting the system from harmful vibrational effects.
Solution Approach 2:
The damping element serves as a mediator that decouples the rigid mounting bracket from the bearing piece. It allows relative movement and absorbs vibrations, reducing the transmission of harmful vibrational forces to the mounting structure while maintaining overall structural stability.
3Manufacturing precision
If complex assembly procedures are used to ensure precision, then assembly precision is improved, but assembly time and complexity increase
Solution Approach 1:
The bearing piece is pre-assembled on the mounting plate before installation. This preliminary action ensures proper positioning and alignment, simplifying the final assembly process. The bearing piece with its receptacle and pin system can be pre-positioned on the mounting plate, reducing the complexity and time of the final assembly operation.
Solution Approach 2:
The mounting plate holder is segmented into a mounting bracket and a bearing piece that can be pre-assembled. This segmentation allows the bearing piece to be prepared in advance and attached to the mounting plate, simplifying the overall assembly process and reducing installation time while maintaining assembly precision.
