Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identification codes are printed on paper or displayed on a screen, then the code structure is fixed and easy to manufacture, but simultaneous recognition from all directions is not possible
Solution Approach 1:
The patent transitions from two-dimensional planar display (paper or screen) to three-dimensional spatial display in air. By forming identification codes as aerial images using laser plasma excitation, the code becomes viewable from multiple angles and directions simultaneously, resolving the contradiction between adaptability for multi-directional recognition and structural complexity.
Solution Approach 2:
The patent introduces dynamic elements by allowing the identification code to change over time through controlled laser scanning and plasma excitation. The code can be updated, modified, or animated in real-time, enabling simultaneous recognition from all directions while maintaining adaptability without requiring a permanently complex physical structure.
2Adaptability or versatility
If information is transmitted using fixed identification codes, then the transmission is reliable, but the information cannot be changed or updated
Solution Approach 1:
The patent employs dynamic laser scanning and plasma excitation to create identification codes that can be changed over time. The same spatial location can display different code patterns at different times, enabling information updates while maintaining reliable transmission through controlled plasma formation and consistent reading mechanisms.
Solution Approach 2:
The patent uses periodic laser scanning and plasma excitation cycles to transmit information. By controlling the timing and sequence of plasma formation at different spatial positions, the system can reliably transmit changing information through repeated, rhythmic patterns that maintain transmission reliability while enabling information adaptability.
3Adaptability or versatility
If a laser beam is used to create plasma emission in space, then dynamic and multi-directional recognition is enabled, but energy consumption increases
Solution Approach 1:
The patent uses periodic laser pulsing rather than continuous illumination. By delivering energy in short, timed pulses that coincide with the laser scanning pattern, the system creates plasma only when and where needed, reducing overall energy consumption while maintaining the capability for multi-directional recognition through the aerial image formation.
Solution Approach 2:
The patent replaces traditional physical display mechanisms (screens, printed materials) with a field-based plasma display in air. This substitution eliminates the need for physical display hardware and enables multi-directional recognition while controlling energy consumption through precise laser timing and spatial targeting of plasma formation.

AI summary
This invention relates to a visible image unit identification code structure using a spatial visible image forming device. A spatial visible image forming device is used that includes: a laser source that emits a laser beam in an invisible region; a scanning means that scans the laser beam; a condensing optical system that condenses the laser beam to a drawing scheduled point in a space so as to cause plasma emission of a gas; and a control means that controls oscillation timing of the laser source and scanning timing of the scanning means so as to generate the plasma emission at the drawing scheduled point in a time series and draw a visible image as an afterimage phenomenon of the plasma emission. A visible image unit identification code formed by combining and arranging multiple kinds of multiple visible image units in different states including different lightnesses/darknesses, colors or shapes or the like is displayed in a space such as in air or in other gases or in water, and information can be transmitted by reading the visible image unit identification code using a reading means from any direction.
