Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If eggs are placed directly in bottle holders or racks, then storage space is utilized, but eggs are easily collided and damaged or contaminated with other foods
Solution Approach 1:
The egg storage system is divided into multiple independent boxes, each capable of rotating independently on the rotating shaft. This segmentation isolates eggs in different boxes from each other, preventing collision and contamination while allowing individual access to each box for egg retrieval.
Solution Approach 2:
A rotating shaft acts as an intermediary mechanism between the user and the eggs. The shaft enables controlled rotation of boxes to bring them to accessible positions, while damping masses serve as intermediaries to control the rotation speed and provide smooth stopping, facilitating easy egg retrieval without direct handling of eggs.
2Ease of operation
If a rotatable storage device is implemented, then egg accessibility is improved, but rotation smoothness and stability are compromised without damping mechanisms
Solution Approach 1:
Damping masses are pre-installed on the rotating shaft to provide cushioning during rotation. These damping masses absorb shocks and vibrations during the rotation process, ensuring smooth operation and stable positioning of boxes before eggs are retrieved, thereby maintaining rotation smoothness while improving accessibility.
3Stability of the object's composition
If damping masses are added to ensure smooth rotation, then rotation stability is improved, but device complexity increases
Solution Approach 1:
The rotating shaft serves multiple functions: it supports the boxes, enables rotation, and provides mounting for damping masses. The damping masses themselves serve dual purposes by both stabilizing rotation and facilitating smooth stopping for egg retrieval. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving rotation stability.
