Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rapid growth in internet technology has increased eye strain and weakened vision due to poor reading habits, such as incorrect postures and reading in low light conditions, especially affecting children whose vision is not yet fully developed.
Innovation Solution
A table lamp equipped with an infrared light sensor, distance detection units, and a control unit that adjusts lighting based on detected infrared light intensity and user proximity, while also monitoring and correcting reading posture through warning signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If people use diverse media devices (smart phone, tablet, notebook, television) to access information, then information accessibility is improved, but eye strain increases and vision weakens
Solution Approach 1:
The patent employs infrared sensors and distance detection units to continuously monitor user presence and reading posture, providing real-time feedback through warning signals when improper reading habits are detected, thereby reducing eye strain while maintaining information accessibility through proper reading conditions
2Use of energy by stationary object
If reading is performed in low light conditions to conserve energy, then energy consumption is reduced, but reading quality deteriorates and vision is impaired
Solution Approach 1:
The patent uses a controllable light source that dynamically adjusts illumination based on detected user presence and reading conditions, providing optimal lighting only when needed rather than continuous illumination, thus balancing energy conservation with vision protection
3Measurement precision
If distance detection units and infrared sensors are added to the table lamp, then reading posture monitoring capability is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the table lamp including lighting, infrared sensing, distance detection, and posture monitoring within a single device, making the lamp serve multiple purposes and reducing the need for separate monitoring equipment, thus managing device complexity while improving measurement precision

AI summary
A table lamp includes an infrared light sensor, a distance detection unit, a light source, and a control unit. The infrared light sensor detects infrared light. The distance detection unit detects a distance between an external object and the distance detection unit. The light source emits light. The control unit controls the light source at least according to intensity of the infrared light detected by the infrared light sensor and the distance detected by the distance detection unit.
