Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional reflectors use solid backings and solid reflective shields with specific fastening means, then mounting security is improved, but adaptability to different traffic guidance materials and shapes deteriorates
Solution Approach 1:
The reflective shield is designed as a universal component that can be mounted on different traffic guidance materials (steel, concrete, wood) and shapes (flat, curved, sloped) using a single adhesive mounting method, eliminating the need for material-specific fastening adaptations
Solution Approach 2:
The mechanical fastening system (bolts, nails, screws) is replaced with an adhesive mounting system using double-sided adhesive tape, allowing the same mounting method to be used across different materials and shapes without requiring mechanical adaptation
2Manufacturing precision
If conventional reflectors use pre-manufactured steel backings, then manufacturing precision is improved, but ease of manufacture and adaptability at mounting location deteriorates
Solution Approach 1:
The backing structure is completely removed from the reflector design, leaving only the reflective shield which is mounted directly onto the traffic guidance object using adhesive, eliminating the need for pre-manufactured backings and their associated adaptation requirements
Solution Approach 2:
The reflective shield is made flexible through material selection and construction, allowing it to conform to different shapes and slopes at the mounting location without requiring pre-manufactured shape adaptations
3Object-affected harmful factors
If conventional reflectors are hidden in guard rail recesses, then safety from traffic impact is improved, but reflective area and visibility deteriorates
Solution Approach 1:
The reflective shield is constructed as a flexible thin film or panel that can protrude from the traffic guidance object without being rigid, allowing it to maintain visibility while being more resistant to breakage upon impact
Solution Approach 2:
The reflective shield transitions from a static, rigid component to a dynamic, flexible component that can deform upon impact rather than breaking, maintaining its reflective function while reducing harm from traffic contact
4Illumination intensity
If conventional reflectors use solid reflective shields, then reflectivity is improved, but ease of operation and safety upon impact deteriorates
Solution Approach 1:
The reflective shield uses composite material construction combining reflective layers with flexible substrate materials, maintaining high reflectivity while providing flexibility to prevent breakage upon impact
