Pre-bonded Thermoplastic Road Marking Sections with Sequential Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermoplastic pavement marking systems require extensive time and labor for assembly and application, as multiple sections need to be manually aligned and adhered to the substrate, often resulting in misalignment and weak bonds due to incompatible adhesives, leading to increased costs and inefficiencies.
Innovation Solution
Preformed pre-bonded thermoplastic sections with integral sequential features and a hot melt adhesive system that allows for efficient assembly and alignment, using features like indents, dimples, or alphanumeric slits to ensure proper matching and bonding, and a polyamide-based adhesive with a matching softening point to maintain pattern integrity during handling and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple independent sections are used to form pavement marking patterns, then design flexibility and visual themes can be achieved, but assembly time and labor effort increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-assembling the thermoplastic marking sections into complete patterns at the factory before shipment. The sections are pre-cut, pre-colored, and pre-arranged in their final configuration with interlocking features already integrated. This eliminates the need for on-site assembly of multiple independent sections, reducing installation time while maintaining design flexibility through pre-configured patterns.
2Adaptability or versatility
If manual assembly of independent sections is performed, then pattern customization is possible, but alignment precision and pattern integrity are compromised
Solution Approach 1:
The patent applies local quality by incorporating specific interlocking features at the interfaces between thermoplastic sections. These features include complementary geometric shapes (such as protrusions and recesses) and adhesive bonding zones positioned at precise locations. The local structural modifications enable automatic alignment and secure connection, ensuring manufacturing precision while allowing overall pattern customization.
3Stability of the object's composition
If spot adhesives are used to maintain pattern integrity during handling, then sections can be held together, but the adhesives create weak bonds and prevent proper attachment to substrate
Solution Approach 1:
The patent applies the taking out principle by removing the problematic spot adhesive layer from the thermoplastic sections. Instead of using separate adhesive spots that create weak bonds and interfere with substrate attachment, the design relies on mechanical interlocking features and integrated bonding surfaces. This extraction of the harmful adhesive element eliminates the bond strength problem while maintaining pattern integrity through structural design.
4Measurement precision
If sections are manually moved for adjustment before heat treatment, then placement accuracy can be achieved, but sections become unaligned and require reinsertion
Solution Approach 1:
The patent applies preliminary action by pre-positioning the thermoplastic sections in their exact final configuration during factory assembly. The interlocking features are designed to maintain precise alignment throughout handling and transportation. This preliminary positioning eliminates the need for manual adjustment at the job site, as the sections remain aligned through the interlocking mechanism without requiring reinsertion or realignment.
5Reliability
If conventional thermoplastic materials are used, then marking visibility and durability are improved, but assembly complexity and labor requirements increase
Solution Approach 1:
The patent applies merging by combining multiple thermoplastic sections into a single pre-assembled unit with integrated interlocking features. The individual sections are manufactured with durable thermoplastic materials maintaining their reliability, but they are merged into a unified structure that simplifies assembly. This merging reduces assembly complexity from handling multiple separate pieces to installing one integrated component while preserving the durability benefits of thermoplastic materials.

AI summary
The present disclosure describes preformed pie-bonded thermoplastic sections comprising smaller articles where the articles and sections have planar top surfaces and planar bottom surfaces that are coplanar to each other There is also an adhesive backing layer on the coplanar bottom sin faces so that the adhesive backing layer bridges and bonds coplanar bottom surfaces to form unified pre-bonded thermoplastic signage thereby ρreventing dislodging or separation of the signage during handling, movement, and or transportation before or during application of the pre-bonded signage. The articles when properly sequenced, matched, and combined, together makeup the sections such that when the sections are also sequenced and matched the sections combine to form thermoplastic signage with a final pattern wherein the planar top surfaces include sequential features necessary to visibly aid in quick assembly of one or more unified thermoplastic signages.
