Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single intermediate connector and a pair of oblique support rods are used to connect two long upper rod bodies, then the device complexity is reduced, but the bearing capacity and stability deteriorate when subjected to significant external forces
Solution Approach 1:
The patent divides the single intermediate connector into two separate connectors (first intermediate connector and second intermediate connector). Each connector independently supports one upper rod body, creating segmented support structures that distribute external forces more effectively. This segmentation resolves the contradiction by maintaining structural simplicity while significantly improving bearing capacity through force distribution.
Solution Approach 2:
The patent combines multiple support elements (two intermediate connectors, two oblique support rods, and vertical support rods) into an integrated support system. This merging creates a redundant structural network where multiple components work together to bear external forces, resolving the contradiction by enhancing bearing capacity through combined structural action while maintaining overall system coherence.
2Ease of manufacture
If a single intermediate connector and oblique support rods are used, then the ease of manufacture is improved, but the stability deteriorates under significant external forces
Solution Approach 1:
By segmenting the support system into multiple independent connectors and support rods, the patent achieves manufacturing simplicity through modular components while improving structural stability. Each segment can be manufactured separately using simple processes, then assembled into a stable configuration that resists external forces effectively.
Solution Approach 2:
The patent applies different structural configurations to different parts of the fence framework. Vertical support rods provide localized vertical stability, oblique support rods provide localized lateral stability, and intermediate connectors provide localized horizontal support. This local quality differentiation resolves the contradiction by achieving overall structural stability through targeted local reinforcements while maintaining manufacturing simplicity.
3Volume of moving object
If long upper rod bodies are used with a single intermediate connector, then the volume for storage is reduced, but the support efficiency deteriorates when suffering from significant external forces
Solution Approach 1:
The patent segments the long upper rod bodies into shorter sections that can be connected through multiple intermediate connectors. This segmentation reduces the storage volume by allowing more compact folding configurations while improving support efficiency through distributed force bearing. The segmented structure can be folded into a smaller package but maintains structural integrity when deployed.
Solution Approach 2:
The patent introduces dynamic connectivity through rotatable joints and hinged connections between rod sections and support elements. This dynamic design allows the structure to adapt its configuration for compact storage while maintaining rigid load-bearing paths when deployed. The dynamic joints enable volume reduction during storage without compromising support efficiency during use.
4Device complexity
If two long upper rod bodies are connected by a single intermediate connector, then the device complexity is reduced, but the reliability deteriorates under significant external forces
Solution Approach 1:
By segmenting the connector system into two separate intermediate connectors, the patent improves reliability through redundant support paths. Each connector independently supports one rod body, creating parallel reliability paths. If one connector fails or is subjected to excessive force, the other continues to provide support, maintaining overall system reliability while keeping the device complexity manageable.
Solution Approach 2:
The patent changes the parameter of connector quantity from one to two, fundamentally altering the reliability characteristic of the system. This parameter change creates a redundant structural configuration where multiple connectors share the load-bearing responsibility, significantly improving support reliability under significant external forces while maintaining acceptable device complexity.
