Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If complex corner connecting elements with multiple components are used, then connection stability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated corner connecting element. The L-shaped connecting element incorporates both first fastening sections for perpendicular profile elements and second fastening sections for parallel profile elements, eliminating the need for separate fixing plates and connectors. This merging reduces the number of components while maintaining connection stability.
Solution Approach 2:
The corner connecting element is designed with multi-functionality to perform multiple connection tasks. It can connect perpendicular profile elements via first plate-shaped fastening sections and parallel profile elements via second plate-shaped fastening sections, making it a universal connector that replaces multiple specialized components.
2Stability of the object's composition
If additional fixing plates and connectors are used to stabilize modular units, then structural stability is improved, but production cost and assembly complexity increase
Solution Approach 1:
The invention merges the functions of corner connectors, fixing plates, and stabilizing elements into a single integrated corner connecting element. This eliminates the need for multiple separate components, reducing production costs through fewer manufacturing processes and inventory items while maintaining modular unit stability.
Solution Approach 2:
The corner connecting element is segmented into functional zones with first plate-shaped fastening sections for perpendicular connections and second plate-shaped fastening sections for parallel connections. This segmentation allows each zone to be optimized for its specific function while being manufactured as a single integrated piece.
3Device complexity
If small area connection points are used in corner connectors, then device simplicity is improved, but load distribution and stability deteriorate
Solution Approach 1:
The patent transitions from point-based connections to surface-based connections by using plate-shaped fastening sections. These extended surface areas distribute loads across larger regions of the profile elements, improving strength and stability while maintaining the simplicity of the connector design through the use of basic L-shaped geometry.
4Reliability
If multiple separate corner connectors are used to connect horizontal and vertical beams, then connection reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The invention merges the functionality of multiple separate corner connectors into a single integrated L-shaped connecting element. This unified connector provides reliable connections for both perpendicular and parallel profile elements, maintaining connection reliability while reducing the number of components from two or more separate connectors to one integrated element.
