Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical components are separately installed and oriented in the display apparatus, then the display apparatus can be assembled with individual components, but the alignment process becomes time-consuming and complex
Solution Approach 1:
The patent combines the film and electrical components into a single integrated unit. The electrical components are mounted directly on the film substrate, eliminating the need for separate installation and alignment steps. This merging of components resolves the contradiction by making assembly easier while reducing the time required for alignment.
2Reliability
If electrical components are separately installed in the display apparatus, then component replacement is possible, but the system becomes susceptible to mechanical deformation and movement of components
Solution Approach 1:
By integrating electrical components directly onto the film substrate, the patent creates a unified structure that eliminates relative movement between components. This integration improves reliability by preventing mechanical deformation and component displacement, while the modular film design maintains ease of replacement.
3Reliability
If the display apparatus uses a closed system design, then protection against environmental influences is improved, but heat dissipation becomes more challenging
Solution Approach 1:
The patent utilizes the film substrate as both a protective enclosure and a heat dissipation pathway. The thin film structure provides environmental protection while maintaining thermal conductivity to external surfaces, resolving the contradiction between sealed protection and heat dissipation.
4Manufacturing precision
If multiple films are used to produce a three-dimensional image, then the depth effect is improved, but the device complexity and cost increase
Solution Approach 1:
The patent integrates multiple imaging films into a single assembled unit with electrical components mounted on each film layer. This combined approach achieves three-dimensional imaging effects while managing complexity through systematic integration and standardized component mounting procedures.

Implementation Method 1
at least one solar cell element (20) is incorporated in the film (5) as the at least one electrical power supply element (18) for the purpose of electrical power generation in the display apparatus (1)
Implementation Method 2
there can furthermore in particular be provision for the film and/or the carrier element to have a further LCD film (15)
Implementation Method 3
By way of example, reflection and/or refraction and/or diffraction in the film can be used to route the light rays produced from the light source to the imaging region of the film
