Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple clips or kits are used to connect adjacent framed profiles, then the device complexity is reduced, but the reliability of the connection structure deteriorates, making it unstable and prone to deformation
Solution Approach 1:
The connection structure is divided into multiple functional components: corner clips for initial positioning, pushrods for triangular bracing, and positioning rods for final fixation. Each component performs a specific function, collectively achieving stable connection without excessive overall complexity.
Solution Approach 2:
Corner clips are installed first to preliminarily position and fix the adjacent framed profiles before the pushrods and positioning rods are added. This preliminary action ensures proper alignment and facilitates subsequent assembly steps.
2Device complexity
If no positioning mechanism is provided during installation, then the device complexity is reduced, but the manufacturing precision of profile placement deteriorates, making it impossible to determine approximate placement positions
Solution Approach 1:
Corner clips are pre-installed on the framed profiles before assembly. These clips serve as preliminary positioning devices that guide the alignment of adjacent profiles during installation, enabling accurate placement without complex positioning mechanisms.
Solution Approach 2:
The corner clips act as intermediary elements between the framed profiles and the connection structure. They provide a reference interface that facilitates precise alignment and positioning during the assembly process.
3Ease of operation
If detachable frames are used to reduce logistics cost, then the ease of operation for carrying is improved, but the reliability of the connection structure deteriorates, leading to potential safety hazards
Solution Approach 1:
The frame is segmented into detachable profiles that can be separated for convenient transport and storage. Despite the detachable nature, the connection between profiles is strengthened through multiple components (corner clips, pushrods, positioning rods) that ensure reliability when assembled.
Solution Approach 2:
Corner clips are pre-installed on the profiles to provide preliminary positioning and stabilization. This preliminary action ensures that even in a detachable frame system, the connection achieves sufficient reliability to prevent safety hazards during use.
4Ease of manufacture
If the frame structure is deformed or scattered, then the ease of manufacture is improved through simple connection, but the strength of the frame deteriorates, causing canvas damage or uneven installation
Solution Approach 1:
The connection system is segmented into multiple specialized components, each addressing a specific structural need: corner clips for positioning, pushrods for triangular bracing and deformation resistance, and positioning rods for final fixation. This segmentation maintains ease of manufacture while ensuring frame strength.
Solution Approach 2:
Corner clips are installed first to preliminarily position the profiles and prevent deformation during subsequent assembly. This preliminary positioning action protects the frame structure from deformation and scattering, ensuring structural integrity.
