Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional vinyl floor graphics are used, then ease of manufacture is maintained, but durability and tensile strength are insufficient
Solution Approach 1:
The patent applies composite materials by combining vinyl with fabric layers and particle receptive layers containing reflective and anti-skid particles. This composite structure significantly improves tensile strength and durability while maintaining manufacturability through integrated layer construction.
Solution Approach 2:
The patent changes the physical and chemical parameters of the floor graphic material by incorporating fabric reinforcement and particle embedment. These parameter changes transform the material from simple vinyl to a multi-functional composite with enhanced mechanical properties.
2Reliability
If traditional floor graphics are used, then cost is reduced, but reliability under vehicular traffic forces deteriorates
Solution Approach 1:
The composite structure with fabric reinforcement and particle layers provides the reliability needed to withstand vehicular traffic forces including static and kinetic friction. The layered composite design distributes and manages these forces across multiple material interfaces.
Solution Approach 2:
The patent segments the floor graphic into distinct functional layers: vinyl base layer, fabric reinforcement layer, and particle receptive layer. This segmentation allows each layer to specialize in specific functions (flexibility, strength, surface enhancement) while working together as an integrated system.
3Illumination intensity
If reflective particles are embedded in the surface, then visibility in low light conditions is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the reflective particle function with the surface layer structure by embedding particles within the particle receptive layer during manufacturing. This integration approach achieves retroreflectivity without requiring separate application steps, maintaining ease of manufacture.
4Object-affected harmful factors
If anti-skid particles are embedded in the surface, then slip resistance is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent combines the anti-skid particle function with the surface layer by embedding particles within the particle receptive layer during the manufacturing process. This integrated approach provides slip resistance without requiring additional post-manufacturing steps.
5Strength
If fabric layer is added to reinforce the vinyl, then tensile strength is improved, but device complexity increases
Solution Approach 1:
The patent segments the structure into distinct layers with the fabric layer positioned between the vinyl and particle receptive layer. This segmentation provides clear functional separation while maintaining a manageable multi-layer construction that can be manufactured using standard lamination processes.
