Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If photovoltaic modules are adhered to fresh concrete using structural adhesive material, then manufacturing time is reduced and process is simplified, but adhesion reliability may be compromised due to the immature state of fresh concrete
Solution Approach 1:
The photovoltaic modules are positioned and adhered to the formwork before the concrete is poured and hardened. This preliminary action allows the modules to be integrated into the concrete structure during the pouring process itself, eliminating the need to wait for concrete hardening and subsequent installation operations, thus significantly reducing manufacturing time while maintaining adhesion reliability through proper adhesive selection and application
Solution Approach 2:
A structural adhesive material serves as an intermediary between the photovoltaic modules and the fresh concrete. This adhesive is specifically selected to maintain its bonding properties when applied to fresh concrete, acting as a mediator that ensures reliable adhesion despite the immature state of the concrete, thereby enabling time reduction without compromising reliability
2Reliability
If complex techniques such as vacuum deposition and polymerization are used to deposit photovoltaic layers on hardened concrete, then adhesion is improved, but device complexity and difficulty of mass production increase
Solution Approach 1:
The complex deposition processes (vacuum deposition, polymerization) are extracted and eliminated from the manufacturing method. Instead, the patent uses a straightforward approach of positioning photovoltaic modules directly on formwork and adhering them with structural adhesive, achieving reliable adhesion through simple, conventional construction techniques that are easy to master and scale for mass production
Solution Approach 2:
The formwork structure itself serves the dual purpose of shaping the concrete and providing a support surface for positioning and adhering the photovoltaic modules during the pouring process. This self-service approach eliminates the need for separate complex deposition equipment and processes, simplifying the overall manufacturing system while maintaining adhesion reliability
