Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If organic electroluminescence display elements are used to provide better color reproduction, then display quality is improved, but battery charge consumption increases significantly
Solution Approach 1:
The patent combines the color filter unit with quantum dots and electrode layers to form an integrated solar cell unit that can simultaneously perform color filtering and photovoltaic energy conversion, merging two functional components into one
Solution Approach 2:
The color filter unit is designed to serve dual purposes: traditional color filtering for display quality and light harvesting for electrical energy generation, making it a multi-functional component that addresses both display performance and power consumption issues
2Power
If display elements use a high proportion of available battery charge, then display performance is maintained, but operational duration decreases
Solution Approach 1:
The solar cell unit enables the display apparatus to generate its own electrical energy from light, allowing the system to partially power itself and reduce reliance on battery charge, thereby extending operational duration
Solution Approach 2:
The patent changes the energy source parameter from solely battery-powered to a hybrid system incorporating photovoltaic energy conversion, fundamentally altering how the display apparatus obtains and sustains power
