Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If concrete barriers are used to prevent tipping, then stability is improved, but weight and mobility deteriorate
Solution Approach 1:
The barrier is divided into modular components: a barrier body and separate support legs that can be independently assembled. This segmentation allows the barrier to achieve stability through proper configuration while maintaining ease of assembly and mobility during transport.
Solution Approach 2:
The support legs are designed to be adjustable and reconfigurable, allowing the barrier to adapt its stability characteristics based on operational needs. The legs can be positioned at different angles and configurations to provide stability when needed while allowing for easy disassembly and mobility.
2Strength
If conventional barriers are made of rigid materials, then strength is improved, but safety deteriorates due to sharp corners
Solution Approach 1:
The barrier design incorporates rounded corners and curved surfaces instead of sharp edges. This curvature eliminates the harmful sharp corners while maintaining the structural strength of the barrier, thereby reducing the risk of injury to crowds and athletes.
Solution Approach 2:
The barrier materials and surface parameters are modified to eliminate sharp corners and edges. The design incorporates rounded geometries and smooth surfaces that maintain structural integrity while removing the harmful characteristics that cause injuries.
3Ease of operation
If barriers are made modular and portable, then ease of operation is improved, but stability deteriorates
Solution Approach 1:
The barrier system is segmented into modular components including the barrier body and separate support legs. This segmentation enables easy assembly and disassembly operations while maintaining stability when properly configured and assembled at the operational site.
Solution Approach 2:
The support legs are designed with adjustable and reconfigurable characteristics, allowing the barrier to transition from a portable state during transport to a stable configuration during use. The legs can be positioned and secured to provide adequate stability while maintaining ease of setup.
4Volume of moving object
If barriers are designed for compact storage, then storage space is reduced, but device complexity increases
Solution Approach 1:
The barrier is divided into separate modular components that can be compactly stored individually. The barrier body and support legs can be stored in a compact configuration and assembled at the operational site, reducing storage volume requirements while maintaining simplicity through standardized connection mechanisms.
Solution Approach 2:
The support legs are designed to nest within or alongside the barrier body when not in use, creating a compact storage configuration. This nesting arrangement minimizes the storage volume required while keeping the assembly process simple through predetermined fit-and-fasten connections.

AI summary
A control barrier includes a barrier wall having a front face and an opposing back face each extending between a top end and an opposing bottom end, a first recess being formed on the front face at the bottom end of the barrier wall. A first slot extends through the barrier wall from the first recess to the back face. A first foot coupled with the barrier wall and being movable between a first position wherein the first foot is at least partially disposed within the recess of the barrier wall and a second position wherein the first foot is rotated a least 45° relative to the first position and is removably positioned within the slot extending through the barrier wall.
