Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional connection wires are employed to connect the display panel to the circuits, then the electrical current generated by the photovoltaic cell can be transmitted to the circuits, but imperfect contact occurs between the additional connection wires and the display panel
Solution Approach 1:
The patent merges the connection wire function with the display panel structure by integrating conductive patterns directly into the panel layers. The conductive patterns are formed as part of the panel's internal structure, eliminating the need for separate external connection wires and ensuring reliable electrical contact between the photovoltaic cell and circuits.
Solution Approach 2:
The patent introduces conductive patterns as intermediary elements that facilitate electrical connection between the photovoltaic cell and external circuits. These conductive patterns are embedded within the display panel structure, serving as a reliable mediator that eliminates contact issues associated with external wire connections.
2Reliability
If additional connection wires are employed to connect the display panel to the circuits, then the electrical current generated by the photovoltaic cell can be transmitted to the circuits, but the manufacturing cost increases
Solution Approach 1:
The patent combines the connection function with the existing display panel manufacturing process by forming conductive patterns as integral parts of the panel structure. This integration eliminates the need for separate wire attachment processes, reducing manufacturing steps and costs while ensuring reliable electrical connections.
Solution Approach 2:
The conductive patterns serve multiple functions: they act as both the display panel's internal conductive elements and the connection medium for transmitting electrical current from the photovoltaic cell. This multi-functionality eliminates the need for dedicated connection wires, reducing manufacturing complexity and cost.
3Reliability
If additional connection wires are employed to connect the display panel to the circuits, then the electrical current generated by the photovoltaic cell can be transmitted to the circuits, but the assembly process becomes more complex
Solution Approach 1:
The patent merges the connection function into the display panel's internal structure through integrated conductive patterns. This integration eliminates the need for separate wire connection steps during assembly, simplifying the manufacturing process and improving production efficiency while ensuring reliable electrical connections.
