Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If table frames are prefabricated in different sizes and welded together, then the required stiffness and stability are achieved, but storage space requirements increase significantly
Solution Approach 1:
The table frame is divided into separate, modular components (profiled bodies and brackets) that can be stored independently in a compact state and assembled when needed. This segmentation allows each component to be optimized for both compact storage and structural performance when assembled.
Solution Approach 2:
The profiled bodies are designed with a trough-shaped cross-section that provides high bending stiffness in the mounting position while allowing the components to be stacked efficiently in a compact configuration for storage and transport, utilizing vertical space effectively.
2Adaptability or versatility
If prefabricated table frames of different sizes are manufactured, then various table configurations are available, but manufacturing complexity and storage costs increase
Solution Approach 1:
The modular components (profiled bodies and brackets) are designed as universal elements that can be combined in different configurations to create table frames of various sizes and specifications. The standardized interface and geometry allow the same components to serve multiple table size requirements.
Solution Approach 2:
By segmenting the table frame into standardized modular components, the system achieves versatility through combinatorial assembly rather than manufacturing entirely different prefabricated frames for each size variant, thereby reducing manufacturing complexity.
3Strength
If welded profile frames are used, then structural stability is ensured, but storage and transportation efficiency decrease
Solution Approach 1:
The welded profile frame is segmented into separate modular components that can be collapsed or stacked into a compact configuration for transport, significantly reducing the volume occupied during logistics while maintaining the capability to form a stable structure when assembled.
Solution Approach 2:
The trough-shaped cross-section of the profiled bodies provides high structural strength in the mounting position while enabling efficient stacking in the vertical dimension during transport, optimizing the trade-off between structural integrity and transport efficiency.
