Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional construction kits use precise fitting connectors and rods, then structural stability is improved, but manufacturing cost and complexity increase due to high tolerance requirements
Solution Approach 1:
The patent changes the geometric parameters of the connectors and rods by introducing deformation capability. The connectors are designed to deform elastically during assembly, allowing for larger manufacturing tolerances while maintaining structural stability through the deformation process rather than relying on precise pre-fitted dimensions.
Solution Approach 2:
The patent introduces dynamic behavior to the connectors, allowing them to deform during assembly and disassembly. This dynamic capability enables the system to accommodate manufacturing variations and provides a mechanical advantage that reduces the need for high-precision manufacturing while maintaining structural integrity.
2Strength
If conventional construction kits use rigid connectors, then assembly strength is improved, but ease of assembly and disassembly deteriorates due to high force requirements
Solution Approach 1:
The connectors are designed to deform elastically during assembly, converting the high force requirement into a controlled deformation process. This dynamic response allows the connector to yield and adapt during insertion, reducing the peak forces required while maintaining strong connections once assembled.
Solution Approach 2:
The elastic deformation capability of the connectors acts as a cushioning mechanism during assembly, absorbing excess force and preventing damage. This beforehand cushioning allows for easier assembly by reducing the peak stresses required while maintaining connection strength.
3Stability of the object's composition
If conventional construction kits use complex assembly mechanisms, then structural integrity is improved, but ease of operation deteriorates due to difficult assembly and disassembly processes
Solution Approach 1:
The patent employs dynamic deformation of connectors to simplify assembly mechanisms. Instead of complex locking or fastening systems, the structural integrity is maintained through controlled elastic deformation during assembly, which naturally provides both the simplicity of operation and the strength of connection.
Solution Approach 2:
The connectors perform their own function of maintaining structural integrity through their elastic deformation capability during assembly and disassembly. This self-service mechanism eliminates the need for separate fastening components or complex assembly procedures, simplifying operation while preserving structural integrity.
4Manufacturing precision
If conventional construction kits use high-tolerance components, then connection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The patent changes the approach to connection accuracy by allowing geometric parameters to vary within larger tolerances. The elastic deformation capability compensates for these variations, maintaining functional accuracy without requiring expensive high-precision manufacturing processes.
Solution Approach 2:
The patent accepts that individual connectors may deform or wear over time, similar to disposable components, but maintains that this is acceptable for the application. This approach allows for cheaper, more easily manufactured components that can be replaced rather than requiring expensive, permanently durable precision parts.
