Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If physical embossing is used to form profiles in substrate, then distinct images can be viewed from different angles, but the profiles must be formed in different vertical substrate spaces
Solution Approach 1:
The patent transitions from forming profiles in different vertical substrate spaces to forming profiles in the same vertical substrate space by utilizing different lateral positions and optical path arrangements. This dimensional shift allows multiple distinct images to be embedded within the same vertical layer, resolving the space constraint while maintaining viewing angle diversity.
Solution Approach 2:
The patent combines multiple profile-forming operations into the same substrate layer and vertical space, merging what were previously separate spatial zones. By integrating multiple sets of embossed profiles with different optical parameters into a single layer, the system achieves multi-angle imaging without requiring additional vertical space.
2Manufacturing precision
If high energy beam is used to form profiles in substrate material, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical embossing methods with high energy beam processing to form profiles in the substrate. This substitution enables precise control of profile geometry and optical parameters while reducing mechanical wear and tooling complexity, though it introduces beam control system complexity.
Solution Approach 2:
The patent utilizes variable parameters of the high energy beam (such as beam energy, focal point, scanning speed, and beam shape) to precisely control the formation of different profile types within the same substrate layer. By dynamically adjusting these parameters, the system achieves manufacturing precision for multiple distinct images without requiring separate processing systems.

AI summary
A method of forming two distinct images in a substrate includes controlling a high-energy beam to form a profile ridge in the substrate, and thereafter defining a first set of features on a first side of the profile ridge, the first set of features representing a first distinct image when the substrate is perceived by an observer from a first angle, as well as defining a second set of features on a second side of the profile ridge, the second set of features representing a second distinct image when the substrate is perceived by an observer from a second angle. Both the first set of features and the second set of features are positioned in a common vertical substrate space of the substrate.
