Solution Overview
Problem
Existing reflective materials, such as those using glass particles, face challenges in achieving reliable adhesion and maintaining reflective capability due to the influence of adhesives, and are not easily deformable for shaping purposes.
Innovation Solution
A method involving a thermoplastic polymer mixture with reflective particles applied on an adhesive layer, where the mixture is polymerized or photoactivated, allowing for durable adhesion and thermal deformation without disrupting the relative orientation of particles, using a monomer mixture with suitable photoinitiators and base materials like polycarbonate, and employing specific curing processes like UV or electron beam activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If glass particles are applied using traditional adhesive mixtures, then adhesion is achieved, but reflective capability is greatly reduced due to the influence of the adhesive on the glass particles
Solution Approach 1:
The patent extracts the adhesive from the mixture with glass particles, applying it as a separate layer first, then positioning the glass particles on top. This separation prevents the adhesive from directly contacting and degrading the reflective surfaces of the glass particles, thereby maintaining high reflectivity while achieving durable adhesion through the adhesive layer beneath.
Solution Approach 2:
The adhesive layer serves as an intermediary between the base material and the glass particles. By placing the adhesive as a mediating layer first, it provides strong bonding to the base material while allowing the glass particles to maintain their reflective surfaces by contacting only the adhesive layer, not the base material directly.
2Strength
If thermosetting materials are used to fix reflective particles, then adhesion is achieved, but the reflective particles displace relative to the base material during later processing
Solution Approach 1:
The patent applies the adhesive layer in advance before positioning the glass particles. This preliminary action allows the adhesive to be in its uncured, positionable state during particle application, and only after the particles are correctly positioned does the curing process begin, thereby preventing displacement during processing while maintaining strong adhesion.
3Ease of manufacture
If traditional reflective materials are used, then reflection is provided, but the materials are not easily deformable for shaping purposes
Solution Approach 1:
The patent uses a two-stage process where the adhesive layer transitions from a dynamic, uncured state during particle positioning to a static, cured state for final fixation. This dynamic property allows the material to be deformable during shaping operations when the adhesive is uncured, then becomes stable after curing, combining ease of manufacture with adaptability.
