Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If flake borosilicate glass is added to polymer material to reduce solar absorptance and net power absorption, then thermal management properties are improved, but mechanical strength and durability may deteriorate
Solution Approach 1:
The patent creates a composite material by combining flake borosilicate glass (1-70 wt%) with polymer material (30-99 wt%). The flake glass particles serve as thermal management agents that reduce solar absorptance and net power absorption, while the polymer matrix provides mechanical strength and durability. This composite structure allows simultaneous achievement of thermal management properties and mechanical integrity.
Solution Approach 2:
The patent optimizes the weight percentage range of flake glass (1-70 wt%) and polymer material (30-99 wt%) to balance thermal management performance with mechanical strength. By controlling these compositional parameters, the invention achieves effective heat rejection while maintaining sufficient structural integrity for practical applications.
2Temperature
If flake borosilicate glass is incorporated into the substrate, then thermal management properties are enhanced, but the complexity of manufacturing increases
Solution Approach 1:
The patent combines flake borosilicate glass particles with polymer material in a single substrate formulation, integrating thermal management functionality directly into the base material. This merging approach eliminates the need for separate thermal management layers or components, simplifying the overall manufacturing process while achieving effective heat rejection.

AI summary
The present disclosure relates to materials, and specifically to materials such as sheet, molded or extruded polymer materials containing flake, formed, powdered, granulated or splintered borosilicate glass for heat rejection or mitigation and enhanced durability and strength. The invention provides a synthetic substrate that includes: 1 to 70 wt % borosilicate glass having an average size of 0.1 to 50 um; and 30 to 99 wt % polymer material, wherein the synthetic substrate has either a denier ranging between 0.1 to 20.0 or a thickness ranging between 0.1 to 20 MIL, which provides thermal management properties including reduction in solar absorptance and net power absorbed by surfaces. The greater the intensity of the solar radiation the more reactive the borosilicate becomes, reflecting and dissipating an increased level of energy.
