Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a standardized container chassis is used, then the structure is simple and easy to manufacture, but the versatility is limited and cannot accommodate various loading types
Solution Approach 1:
The chassis frame is divided into multiple separable sections with standardized locking interfaces. Each section can be independently manufactured and then assembled through the locking assembly, allowing the chassis to be segmented for easy manufacturing while reconfigured for different loading requirements.
Solution Approach 2:
The locking assembly is designed with universal compatibility to work with various chassis frame configurations and loading types. The standardized locking interface allows the same locking mechanism to secure different container types, making the system multi-functional and adaptable to diverse cargo requirements.
2Device complexity
If manual fastening operations are used, then the device complexity is low, but the fastening strength is weak and clearance issues occur
Solution Approach 1:
The manual mechanical fastening operation is replaced with an automated locking assembly that uses a cylinder mechanism. When the chassis frames are positioned, the cylinder automatically extends to engage the locking unit, providing strong fastening without requiring manual intervention and eliminating clearance issues through precise automated positioning.
Solution Approach 2:
The locking assembly is designed to automatically perform the fastening operation when the chassis frames are brought into contact. The system self-activates through the contact between frames, triggering the cylinder to extend and lock the frames together without external intervention, thereby achieving strong fastening with minimal complexity.
3Strength
If a locking assembly with automated cylinder configuration is used, then the fastening strength is enhanced and clearance is eliminated, but the device complexity increases
Solution Approach 1:
The locking assembly merges multiple functions into a single integrated unit: the cylinder mechanism, locking unit, fluid pressure unit, and control switches are combined into one compact assembly. This consolidation provides enhanced fastening strength while minimizing the overall complexity by eliminating separate components and reducing installation complexity.
Solution Approach 2:
The automated locking assembly activates itself through the contact between chassis frames. The first switch detects frame contact and automatically triggers the fluid pressure unit to extend the cylinder, eliminating the need for external control systems or complex manual operation mechanisms, thereby achieving strong fastening with relatively simple device architecture.
4Stability of the object's composition
If chassis frames are permanently fixed, then the structural stability is high, but the adaptability for selective extension and different loading types is reduced
Solution Approach 1:
The chassis frame transitions from a permanently fixed state to a dynamic, reconfigurable structure. The locking assembly allows frames to be securely fixed when needed for stability during transport, and easily released or repositioned when selective extension or reconfiguration is required, providing both stability and adaptability through controllable locking and unlocking operations.
