Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rack post impact absorption devices or prefabricated shock absorbing bollards are used, then collision protection is provided, but additional fencing must be installed and expansion flexibility is limited
Solution Approach 1:
The bollard fence is divided into modular components including multiple ground fixing members, vertical poles, horizontal frames, and connecting members that can be independently assembled and configured. This segmentation enables the fence to be expanded or reconfigured by simply adding or removing modules without requiring complete replacement of the protection system.
Solution Approach 2:
The connecting members and couplers are designed with universal interfaces that can accommodate different configurations of ground fixing members, vertical poles, and horizontal frames. This multi-functionality allows the same basic components to serve various protection needs and expansion requirements, eliminating the need for additional specialized fencing structures.
2Reliability
If additional fencing is installed around rack posts, then collision protection is improved, but device complexity and installation requirements increase
Solution Approach 1:
The ground fixing members, vertical poles, horizontal frames, and connecting members are merged into an integrated bollard fence system where each component serves multiple functions. The connecting members simultaneously provide structural support, enable expansion, and simplify installation, reducing the overall complexity compared to traditional separate fencing systems.
Solution Approach 2:
The modular design with standardized interfaces enables the fence to be self-assembled and self-expanded by simply connecting pre-fabricated modules together. The system serves itself through repeatable connection patterns that eliminate the need for complex installation procedures or specialized additional fencing structures.
