Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile lighting devices often accidentally switch to lower brightness modes due to delayed obstruction detection, leading to inadequate illumination in situations like rain or close-range observations.
Innovation Solution
A control method for mobile lighting devices that performs obstruction detection only within a set time after mode switching, and adjusts the brightness mode accordingly, thereby reducing unnecessary switching to lower brightness modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If obstruction detection is performed continuously after mode switching, then the device can respond to obstructions timely, but it causes unnecessary mode switches in scenarios like rain or close-range observations
Solution Approach 1:
The patent applies preliminary action by performing obstruction detection only within a predetermined time period after mode switching. This limited-time detection window allows the device to respond to genuine obstructions while avoiding false detections from temporary conditions like raindrops or close-range observations, thereby stabilizing brightness mode operation.
2Ease of operation
If obstruction detection is performed within a set time only, then unnecessary mode switches are reduced, but the response time for obstructions may be delayed
Solution Approach 1:
The patent performs obstruction detection in advance within a predetermined time period after mode switching, before the device enters stable operation. This preliminary detection phase ensures that genuine obstructions are detected and addressed promptly, while the limited time window prevents unnecessary mode switches from temporary obstructions.
3Object-affected harmful factors
If the device switches to lower brightness mode upon detecting obstruction, then safety is improved, but illumination quality deteriorates in valid lighting scenarios
Solution Approach 1:
The patent performs obstruction detection within a predetermined time period after mode switching, before the device enters stable operation. This timing ensures that genuine obstructions are detected and addressed promptly, while the limited time window prevents false detections from temporary conditions like raindrops or close-range observations, thereby maintaining appropriate brightness levels.
Solution Approach 2:
The patent implements a feedback mechanism where the obstruction detection result within the predetermined time period directly controls the brightness mode selection. If an obstruction is detected during this critical period, the device switches to a lower brightness mode to ensure safety. If no obstruction is detected, the device maintains the higher brightness mode for optimal illumination, thus balancing safety and lighting quality.
