Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional reservation formwork corner elements are used, then the formwork can be assembled, but they are not adaptable to different dimensions and shapes, particularly failing to create non-standard angles
Solution Approach 1:
The corner element incorporates an articulation mechanism that allows the angle between the two seats to be adjusted dynamically. This enables the formwork to adapt to different dimensions and shapes, including non-standard angles, while maintaining a relatively simple structural design through the use of a single adjustable component rather than multiple fixed-angle pieces.
2Ease of operation
If conventional reservation formwork corner elements are used, then the formwork can be assembled, but they are difficult to use without specialized tools
Solution Approach 1:
The corner element replaces complex mechanical fastening systems with a simplified articulation mechanism that can be adjusted and secured more easily. The articulation allows for tool-free or minimal-tool adjustment of angles, improving ease of operation while maintaining assembly stability through the inherent mechanical interlock of the articulated joints.
3Adaptability or versatility
If adjustable corner elements are implemented, then adaptability to different angles is improved, but the complexity of the corner element increases
Solution Approach 1:
The corner element is segmented into two distinct seats connected by an articulation, allowing each seat to be optimized for its specific function while the articulation provides the necessary adjustability. This segmentation enables adaptability to different angles without requiring the entire corner element to be overly complex, as each segment remains relatively simple in design.
