Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing visual impairment devices are ineffective in creating a 'No-Go' zone to deter intruders without precise targeting, as they require accurate aiming at the intruder's eyes, which is challenging due to unknown or moving targets.
Innovation Solution
A visual impairment device with a light source generating multiple high-intensity beams of different wavelengths, modulated to create a spatial array of light that covers an area, disrupting binocular vision without the need for precise targeting, using a controller to manage the light source and modulator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a laser device is used to impair vision, then visual disruption is achieved, but precise targeting is required which is difficult when intruder position is unknown
Solution Approach 1:
The patent segments the single laser beam into multiple separate beams that are spatially distributed to cover an area. Instead of requiring one precise beam to hit the intruder's eyes, the system creates multiple beams across a zone, increasing the probability that at least one beam will enter each eye without requiring precise targeting.
Solution Approach 2:
The patent transitions from a point-target approach (single beam at specific coordinates) to an area-cover approach by distributing beams across a two-dimensional spatial array. This dimensional expansion from 0D point to 2D area allows the system to impair vision without precise targeting by ensuring coverage of the entire potential intruder zone.
2Adaptability or versatility
If a single beam is used, then the device is simpler to design, but it cannot effectively cover an area without precise targeting
Solution Approach 1:
The single laser source is segmented into multiple independent beams through optical elements. This segmentation allows the system to cover an area while maintaining a relatively simple single-source architecture, avoiding the need for multiple independent laser devices.
Solution Approach 2:
A single laser source performs multiple functions by generating multiple spatially distributed beams. This multi-functionality allows one device to both simplify the overall system architecture and achieve area coverage, eliminating the need for separate targeting and area coverage systems.
3Reliability
If high intensity light is used to disrupt vision, then temporary incapacitation is achieved, but the risk of permanent eye damage increases
Solution Approach 1:
The patent applies different characteristics to different parts of the light field by creating a spatial array where individual beams are distributed across an area. This allows the system to use high intensity locally in each beam for effective disruption while distributing the overall energy across a larger area, reducing the density and potential for permanent damage compared to a concentrated single beam.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively creates a visual impairment zone that deters intruders by causing temporary visual disruption, making it difficult for them to enter or navigate through the area without causing permanent eye damage.
Implementation Method 1

AI summary
A visual impairment device includes a light source, a modulator, and a controller. The light source capable of generating two or more high intensity light beams having different peak wavelengths, wherein at least one of the light beams has a wavelength bandwidth of less than 100 nm. The modulator modulates the two or more beams of intense light to produce a spatial array comprising a first array of first light beams having a first peak wavelength and a second array of second light beams having a second peak wavelength different from the first wavelength. The controller includes control circuitry for controlling the light source, the modulator, or both. The spatial array is projected into a space such that a lateral distance of at least one first light beam to a second light beam is in a range of 40-110 mm within at least one area of the space.
