Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If phosphor compounds are used as phase change materials for thermal storage, then heat storage capability is improved, but the system relies on latent heat storage which limits temperature range and physical toughness
Solution Approach 1:
The patent changes the fundamental parameter of heat storage mechanism from latent heat storage to sensible heat storage by using phosphor compounds in a different physical state and configuration. This allows the material to store heat through temperature change rather than phase change, enabling broader temperature ranges and improved physical properties suitable for building materials
Solution Approach 2:
The patent creates a composite material system combining phosphor compounds with construction materials like concrete or cement. This composite approach allows the phosphor compounds to provide high heat capacity while the construction material matrix provides structural strength and physical toughness, achieving both thermal storage functionality and building material requirements
2Use of energy by moving object
If thermal storage systems based on salts are used, then heat storage is achieved, but material costs increase due to need for corrosion resistant tubing and tanks
Solution Approach 1:
The patent replaces expensive corrosion-resistant materials (specialized tubing and tanks) with conventional, inexpensive construction materials like concrete or cement. The phosphor compound-infused construction material serves as both the thermal storage medium and the structural container, eliminating the need for separate expensive corrosion-resistant components
Solution Approach 2:
The construction material serves multiple functions simultaneously: it provides structural support, acts as the containment vessel, and serves as the thermal storage medium through the incorporated phosphor compounds. This multi-functionality eliminates the need for separate specialized components, reducing overall system cost
3Use of energy by moving object
If phosphor compounds are used for thermal storage, then heat storage capability is improved, but physical toughness is insufficient for use as building materials
Solution Approach 1:
The patent creates a composite material system where phosphor compounds are integrated into a construction material matrix (concrete, cement, or similar materials). The construction material matrix provides the necessary structural strength, rigidity, and physical toughness, while the phosphor compounds contribute high heat capacity for thermal storage functionality
Solution Approach 2:
The patent uses solid core particles as carriers for the phosphor compounds, creating a segmented structure where the core particles are distributed within the construction material matrix. This segmentation allows the phosphor compounds to be effectively distributed throughout the material while maintaining the structural integrity provided by the construction material framework
