Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If transponders are attached to formwork elements for anti-theft monitoring, then theft protection is provided, but the monitoring range is limited and large-area monitoring cannot be achieved
Solution Approach 1:
The patent replaces the mechanical transponder system with an electromagnetic signal module system. The signal module uses electromagnetic signals to communicate with base stations, enabling long-range monitoring without the physical limitations of transponders. This substitution allows large-area monitoring while maintaining reliable theft protection.
Solution Approach 2:
The patent transitions from localized point-to-point transponder communication to a multi-dimensional electromagnetic signal transmission system. The signal module can communicate with multiple base stations across a large area, creating a spatial monitoring network that covers extensive construction sites.
2Ease of operation
If the formwork element surface is made smooth for easy demolding, then demolding is facilitated, but the surface is vulnerable to moisture and mechanical influences
Solution Approach 1:
The patent uses a multi-layer surface structure where the base layer is embedded within the formwork element, the separating layer is applied over the base layer, and the signal module is protected within the base layer. This nested structure allows the smooth separating layer to contact concrete while the base layer protects the signal module from moisture and mechanical damage.
Solution Approach 2:
The patent creates a composite surface structure combining different materials with complementary properties. The base layer provides protection against moisture and mechanical influences, while the separating layer provides smoothness for easy demolding. This composite structure resolves the contradiction between surface smoothness and protection.
3Reliability
If the base layer is made waterproof to protect the signal module, then protection against moisture is improved, but the separating properties with concrete may be compromised
Solution Approach 1:
The patent applies different properties to different layers: the base layer is waterproof to protect the signal module from moisture, while the separating layer is designed to be concrete-repellent to prevent adhesion. This local differentiation of properties allows both protection and easy demolding without compromise.
