Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security verification devices using laser class 1 fail to generate clear reflection points for machine-testable features in hologram film and security threads due to insufficient luminous intensity and wavelength, violating safety regulations.
Innovation Solution
A device with a laser pointer that emits high-intensity light within specified safety limits, featuring a housing with a through-hole, a fixing device, and a translucent or transparent intermediate layer, allowing precise alignment and safe operation, and includes LED illumination for improved visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If laser class 1 is used to comply with safety regulations, then safety requirements are met, but the reflection points for machine-verifiable features can only be generated with insufficient clarity
Solution Approach 1:
A translucent mold is introduced as an intermediary element between the laser and the security features. The mold concentrates and directs the laser light to create sufficiently clear reflection points while maintaining laser class 1 safety requirements. The mold acts as a mediator that enables the verification function without requiring higher laser power.
Solution Approach 2:
The patent changes the optical parameters by using a translucent mold with specific geometric properties to concentrate the laser light. This parameter change allows the system to achieve adequate reflection point clarity with laser class 1, transforming the optical interaction to meet both safety and verification requirements.
2Measurement precision
If a translucent mold is used to concentrate laser light, then reflection point clarity is improved, but the housing must be designed opaque to enclose the mold while allowing viewing openings
Solution Approach 1:
The housing is designed with differentiated local qualities: opaque sections to enclose and protect the mold and laser components, and transparent viewing openings to allow observation of the verification process. This local differentiation of transparency resolves the contradiction between enclosure and visibility requirements.
Solution Approach 2:
The housing is segmented into functional zones: an opaque enclosure for the laser and mold mechanism, and separate viewing openings for observation. This segmentation allows each zone to fulfill its specific function while resolving the overall structural contradiction.
3Object-affected harmful factors
If the receiving space is spaced apart from the mold, then safety distance is maintained, but the device size increases
Solution Approach 1:
The receiving space is nested within or adjacent to the mold structure rather than being completely separate. This nesting arrangement maintains the necessary safety distance while minimizing the overall device volume by efficiently utilizing space.
Solution Approach 2:
The receiving space is positioned in a different spatial dimension or orientation relative to the mold, allowing safety distance to be maintained in one dimension while keeping the device compact in other dimensions. This dimensional arrangement resolves the space conflict.
