Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connections are used to fasten the holding profile to the supporting structure, then reliable structural support is achieved, but assembly time increases and thermal bridges are created
Solution Approach 1:
The patent replaces the mechanical screw connection system with a friction-based clamping system. The holding profile is designed with a clamping mechanism that secures the membrane construction to the supporting structure through friction force generated by a clamping element, eliminating the need for screws and thereby reducing assembly time while maintaining structural support.
Solution Approach 2:
The patent extracts and removes the screw fastening elements from the holding device design. By taking out the screws and associated fastening hardware, the design achieves simpler assembly procedures and reduces the time required for installation, while still providing adequate structural support through the friction-based clamping mechanism.
2Strength
If screw connections are used to fasten the holding profile to the supporting structure, then reliable structural support is achieved, but thermal bridges are created reducing thermal insulation
Solution Approach 1:
The patent introduces a friction element as an intermediary component between the holding profile and the supporting structure. This friction element acts as a thermal break, preventing direct thermal contact and the formation of thermal bridges, while still transmitting the necessary mechanical clamping force to maintain structural support.
3Strength
If screw connections are used to fasten the holding profile to the supporting structure, then reliable structural support is achieved, but contact corrosion occurs in aggressive environments
Solution Approach 1:
The patent introduces a friction element as an intermediary barrier between the holding profile and the supporting structure. This friction element prevents direct metal-to-metal contact that would lead to contact corrosion, while still transmitting the necessary clamping force. The friction element can be made from corrosion-resistant materials or coated surfaces.
4Strength
If multiple bores are provided on the supporting structure for screw connections, then reliable fastening is achieved, but assembly complexity and costs increase
Solution Approach 1:
The patent extracts and eliminates the need for multiple bores in the supporting structure by replacing the screw fastening system with a friction-based clamping system. The holding profile can be directly clamped onto the supporting structure without requiring pre-drilled holes, thereby simplifying the assembly process and reducing the number of components needed.
5Loss of time
If a clamping mechanism is used to attach the holding profile, then assembly time is reduced, but additional components are required
Solution Approach 1:
The patent merges the clamping mechanism components into an integrated holding profile design. The friction element and clamping structure are combined into a single unified component that can be directly attached to the supporting structure, eliminating the need for separate fastening elements and reducing the total number of parts while maintaining quick assembly capability.
