Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple optical components are used to implement the optical system, then the augmented reality image can be output to the wearer's eyeballs, but the weight of the apparatus increases significantly
Solution Approach 1:
The patent combines multiple optical components (lens, prism, mirror) into a single integrated optical system that performs all necessary functions (image output, light reflection, refraction) through one compact structure, thereby reducing overall weight while maintaining functionality
Solution Approach 2:
The patent employs thin-film optical elements and lightweight optical materials to create the optical system, replacing traditional bulky optical components with thinner, lighter alternatives that maintain optical performance while significantly reducing weight
2Reliability
If multiple optical components are arranged in the optical system, then the augmented reality image can be displayed, but the visual field is blocked
Solution Approach 1:
The patent positions the optical system in a spatial configuration that utilizes three-dimensional space efficiently, arranging components to minimize projection into the wearer's visual field while maintaining optical path integrity
Solution Approach 2:
By using thin-film optical components, the patent reduces the physical thickness and visual obstruction of the optical system, allowing light from the real world to pass through with minimal blockage while still performing necessary optical functions
3Reliability
If the apparatus is designed in a large size like HMD, then all necessary components can be included, but the wearer experiences considerable inconvenience
Solution Approach 1:
The patent nests the optical system within the frame structure of the glasses, integrating components into the existing glassware architecture rather than adding separate bulky units, thereby maintaining component functionality while achieving a compact wearable form
Solution Approach 2:
The patent merges the optical system with the glasses frame structure, combining the functions of the wearable framework and the optical housing into a single integrated design, eliminating the need for separate large-sized optical modules
4Ease of operation
If the apparatus is compacted to glasses size, then wearing convenience is improved, but the optical system weight increases
Solution Approach 1:
The patent uses thin-film optical elements and lightweight materials to construct the compact optical system, enabling glasses-sized dimensions without proportionally increasing weight through the use of advanced thin-film technologies
Solution Approach 2:
The patent replaces traditional mechanical optical components with holographic optical elements that use light diffraction principles, eliminating the need for heavy mechanical structures while maintaining optical functionality in a compact form
