Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional single-panel solar systems are used, then the structure is simple and easy to manufacture, but the energy generation capacity is limited due to fixed orientation and area
Solution Approach 1:
The solar energy collection system is divided into multiple independent solar panels, each with its own substrate and solar cells. These panels can be individually oriented and connected through conductors, allowing each segment to capture energy from different directions and angles, thereby increasing total energy generation capacity while maintaining manufacturing simplicity for each individual panel
Solution Approach 2:
The system transitions from a single fixed-panel configuration to a multi-panel three-dimensional arrangement where panels are oriented at different angles and directions. This spatial dimensionality change allows simultaneous capture of sunlight from multiple directions (front, back, side lighting), resolving the contradiction between structural simplicity and energy generation capacity
2Productivity
If individual solar panels with fixed orientation are used, then the manufacturing process is simple, but the energy collection efficiency is restricted by the fixed area and orientation
Solution Approach 1:
Multiple solar panels with different orientations are merged into a single integrated system through electrical conductors that connect the solar cells across panels. This merging allows the system to function as a unified energy collection unit while maintaining the manufacturing simplicity of individual standardized panels, thereby improving overall energy collection efficiency without significantly increasing assembly complexity
Solution Approach 2:
Each solar panel in the multi-panel system serves multiple functions: it collects direct sunlight on its front surface, reflects and captures light on its back surface, and can be oriented to capture side lighting. This multi-functionality of each panel component improves overall energy collection efficiency while each panel itself remains a standardized, easily manufactured unit
