Solution Overview
Problem
Conventional lamps require manual adjustment of height or direction to change lighting regions, which is inconvenient and results in poor spotlight angle adjustment, failing to meet dynamic user lighting needs.
Innovation Solution
A lamp holder device with a sector-shaped shell, LED lamp plate, motor component, light reflecting component, camera shooting component, and microprocessor that uses eye tracking technology to automatically adjust the light emission angle based on the user's gaze direction, enabling automatic lighting region changes and improved spotlight angle adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of lamp pole height or lamp holder direction is used to change lighting region, then lighting region can be changed, but user convenience deteriorates and spotlight angle adjustment effect becomes poor
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated eye-tracking system. The camera shooting component captures user gaze direction, the microprocessor analyzes the gaze data to determine the desired lighting region, and the motor component automatically adjusts the light reflecting component's angle accordingly. This substitutes the manual mechanical adjustment system with an automated optoelectronic control system, dramatically improving ease of operation while maintaining precise spotlight angle adjustment.
Solution Approach 2:
The lighting system serves itself by automatically detecting user gaze direction and adjusting the lighting region without manual intervention. The eye tracking technology enables the system to self-adjust based on user needs, eliminating the need for users to manually operate adjustment mechanisms. This self-service approach resolves the contradiction by making the system both easy to operate (automatic) and capable of precise adjustment (motor-driven light reflecting component rotation).
2Ease of manufacture
If fixed installation of lamps is used, then installation simplicity is improved, but adaptability to changing user field of view deteriorates
Solution Approach 1:
The patent transforms the fixed lighting system into a dynamic one by introducing a motor component that can rotate the light reflecting component. The system maintains simple fixed installation of the lamp holder device itself, but adds dynamic adjustment capability through the motor-driven reflection angle control. The light reflecting component's rotatable design allows the lighting region to dynamically adapt to user field of view changes while keeping the overall installation simple and fixed.
Solution Approach 2:
The system changes the emission angle parameter of the lighting system by rotating the light reflecting component. Instead of changing the physical position or orientation of the entire lamp (which would complicate installation), the patent adjusts the lighting parameters by changing the reflection angle through motor-driven rotation. This allows the fixed-installed lamp to adapt its lighting region dynamically, resolving the contradiction between installation simplicity and adaptability.
3Device complexity
If conventional manual adjustment methods are used, then device structure remains simple, but lighting control precision deteriorates
Solution Approach 1:
The patent replaces imprecise manual mechanical adjustment with a precision optoelectronic control system. The camera shooting component provides precise gaze detection, the microprocessor performs accurate angle calculation based on gaze position, and the motor component executes precise rotational adjustment of the light reflecting component. This substitution transforms the adjustment mechanism from simple but imprecise manual control to a more complex but highly precise automated system, resolving the contradiction between structural simplicity and adjustment precision.
