Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination devices, such as flashlights and cameras, are user-unfriendly due to the need for manual adjustment of light intensity and beam shape, which is cumbersome and inefficient.
Innovation Solution
An illumination device with a light source and an adjustable optical element controlled by a controller that adjusts light intensity and beam shape automatically in response to an adjusting control signal, eliminating the need for manual lens shifting and providing options for continuous, flashing, or combined light modes with adjustable intensity and beam direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of lens and light intensity is used, then device structure remains simple, but ease of operation deteriorates
Solution Approach 1:
The illumination device automatically adjusts light intensity and beam shape based on detection signals without requiring manual intervention. The controller autonomously controls the light source and adjustable optical element, allowing the device to serve itself rather than requiring user operation for adjustments.
Solution Approach 2:
The patent replaces manual mechanical adjustment of lenses and light intensity with an automated control system. The controller uses electrical signals to adjust the optical elements and light source intensity, substituting mechanical user interaction with an automated electromechanical control system.
2Ease of operation
If automated controller adjusts light intensity and beam shape, then ease of operation improves, but device complexity worsens
Solution Approach 1:
The controller serves multiple functions: it controls light source intensity, adjusts optical element positioning, and coordinates between detection and illumination components. This multi-functionality consolidates what would otherwise require separate control mechanisms into a single integrated unit, managing complexity through functional consolidation.
Solution Approach 2:
The patent combines the control of light intensity and beam shape adjustment into a single integrated controller system. Rather than having separate mechanisms for intensity control and optical element adjustment, both functions are merged under one control unit that receives detection signals and coordinates adjustments accordingly.
3Adaptability or versatility
If multiple light modes (continuous, flashing, combined) are provided, then adaptability improves, but use of energy worsens
Solution Approach 1:
The illumination device provides flashing light mode where the light source operates in periodic on-off cycles rather than continuously. This periodic action reduces average energy consumption compared to continuous operation while still providing effective illumination for photography purposes, allowing the device to adapt to different shooting requirements.
Solution Approach 2:
The controller dynamically changes light source parameters including intensity levels and temporal patterns (continuous vs. flashing) based on detection signals and required illumination conditions. By adjusting these parameters rather than operating at fixed high intensity, the device achieves adaptability to different scenarios while managing energy consumption more efficiently.
