Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional irradiation devices have fixed beam angles, making them inadequate for applications requiring multiple beam angles, and their complexity and cost make them difficult for average users to operate and install, especially when trying to achieve variable beam angles.
Innovation Solution
A device with a housing assembly and a rotate and lock mechanism that allows for rotational adjustment of lenses to change the beam angle, using a radiation source with LEDs that can emit UV, visible, and infrared radiation, allowing for various beam angles to be achieved through the relative rotation of the lenses and radiation source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple irradiation devices with different fixed beam angles are used to achieve variable beam angles, then the beam angle requirements are met, but the device complexity and cost increase
Solution Approach 1:
A single irradiation device is designed with multiple lenses having different focal lengths, allowing one device to perform multiple beam angle functions. The device can switch between different beam angles by changing the lens configuration, eliminating the need for multiple separate devices with fixed beam angles.
Solution Approach 2:
The irradiation device incorporates adjustable lens configurations that can dynamically change the beam angle during operation. The lens assembly can be repositioned or reconfigured to alter the focal length, enabling the device to adapt to different beam angle requirements rather than being fixed at one angle.
2Adaptability or versatility
If external attachments are added to achieve variable beam angles, then the beam angle can be adjusted, but the device bulk and operational complexity increase
Solution Approach 1:
The adjustable lens assembly is integrated directly into the housing of the irradiation device, merging the beam angle adjustment mechanism with the main device structure. This eliminates the need for separate external attachments and simplifies operation by making the adjustment feature inherent to the device itself.
Solution Approach 2:
The lens assembly is positioned within the housing structure in a nested arrangement, where the adjustable lenses are contained within the device body rather than being external attachments. This nesting approach reduces bulk while maintaining the variable beam angle capability.
3Adaptability or versatility
If reflective optic members are used to control beam angle, then the beam angle can be adjusted, but the device cost and complexity increase
Solution Approach 1:
The invention uses simple refractive lenses instead of expensive reflective optic members. These lenses can be manufactured using conventional, cost-effective methods and do not require complex alignment or specialized materials, significantly reducing manufacturing costs while achieving the same beam angle control function.
Solution Approach 2:
The patent replaces complex reflective optical systems with simpler refractive lens-based systems. This substitution uses basic optical principles that are easier to manufacture and align, reducing both device complexity and manufacturing cost while maintaining beam angle adjustability.
