Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional display elements are used in windshields or smart glasses, then data can be provided to users, but the devices become bulky and cannot be integrated into space-constrained applications
Solution Approach 1:
The patent transitions from conventional 2D display surfaces to 3D volumetric holographic imaging. The holographic layer creates images in three-dimensional space rather than on a flat surface, enabling compact integration while maintaining versatile display capabilities across multiple planes and orientations.
Solution Approach 2:
The patent uses thin holographic films or layers that can be integrated into transparent carriers such as windshields or spectacle lenses. These thin-film holographic elements provide display functionality without adding significant bulk, enabling integration into space-constrained applications like smart glasses and vehicle windshields.
2Ease of operation
If data are superimposed on transparent carriers, then users can perceive both data and environment, but existing devices are not compact enough for applications like smart glasses
Solution Approach 1:
The holographic imaging system creates images in three-dimensional space at various depths, allowing users to perceive data without averting their gaze while maintaining a compact form factor. The volumetric nature of holographic displays enables efficient use of space compared to conventional planar displays.
3Productivity
If conventional displays are used in smart glasses, then data can be provided, but compact solutions are required due to limited space
Solution Approach 1:
The patent employs holographic imaging to represent data in three-dimensional space rather than on a two-dimensional surface. This dimensional transition allows multiple images to be displayed in different planes and orientations within a compact volume, significantly increasing data representation capability while reducing device size for smart glass applications.
4Loss of information
If images are represented in multiple planes, then more information can be conveyed, but device complexity increases
Solution Approach 1:
The holographic layer serves multiple functions simultaneously: it can display multiple images in different planes, provide optical correction through integrated lenses, and maintain transparency for environmental visibility. This multi-functionality reduces the need for separate optical components, thereby managing complexity while enabling comprehensive information representation.
