Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard uniform barrier members are used, then manufacturing and assembly are simplified, but the barriers cannot adapt to different environments and conditions
Solution Approach 1:
The barrier member incorporates adjustable legs that can be repositioned along the longitudinal axis, allowing the barrier to dynamically adapt to different ground conditions and environmental requirements while maintaining a standardized design
Solution Approach 2:
The standardized barrier member is designed to perform multiple functions across different environments through its adjustable components, enabling a single universal design to serve various crowd control scenarios without requiring custom-made barriers for each situation
2Strength
If barrier members are made fixed and rigid, then structural strength is improved, but the barriers become unstable on uneven ground and present tipping hazards
Solution Approach 1:
The legs are designed with adjustable positioning mechanisms that allow them to be moved along the longitudinal axis to achieve optimal positioning on uneven ground, maintaining both structural strength and stability by adapting the rigid structure to the terrain
Solution Approach 2:
The barrier member allows for parameter changes in leg position and orientation, enabling the rigid structure to adapt to varying ground conditions while maintaining its structural integrity and resistance to tipping forces
3Adaptability or versatility
If barrier members are used in temporary locations, then crowd control flexibility is improved, but transportation and relocation become inefficient
Solution Approach 1:
The barrier system is divided into modular barrier members that can be easily assembled, disassembled, and transported, reducing the time and effort required for relocation while maintaining flexibility for temporary crowd control applications
Solution Approach 2:
The adjustable legs and modular design enable rapid deployment and reconfiguration of barriers at different temporary locations, minimizing setup time and maximizing the flexibility needed for various crowd control scenarios
4Adaptability or versatility
If adjacent barriers are not aligned on uneven ground, then adaptability to terrain is improved, but safety is reduced due to tripping hazards and bumping risks
Solution Approach 1:
The adjustable legs allow each barrier member to dynamically adapt to the local terrain while maintaining alignment with adjacent barriers through coordinated leg positioning, eliminating tripping hazards and bumping risks even on uneven ground
Solution Approach 2:
The barrier system enables parameter changes in leg position and height to accommodate uneven terrain while maintaining proper alignment between adjacent barriers, reducing safety hazards without sacrificing adaptability to the terrain

AI summary
A crowd control barrier (20) including a barrier member with side legs (24) and feet (40) connected to the legs, each foot having a foot member (45) extending transverse to the barrier member. The leg-foot connections include a bracket (42) extending up from the connected foot member and spaced substantially parallel top and bottom pins (60, 62) on the legs. The bracket has a substantially vertical slot (56) above a transverse slot (58) with the top pin slidably received in the vertical slot and the bottom pin movable transversely in the transverse slot. Teeth (70) project upwardly from the bottom of the transverse slot (58) with the teeth upper ends spaced less than the pin spacing from the bottom of the vertical slot. Lifting a leg slides the top pin up in the vertical slot and moves the bottom pin above the teeth whereby the leg and foot may be pivoted about the top pin whereby the bottom pin moves transversely in the second slot.
