Suspended Lamp Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suspended lamps for plant lighting are difficult to adjust in height, leading to inefficient light distribution and high energy consumption, as they cannot be easily lowered or raised to match plant growth stages.
Innovation Solution
A device with a guide roller combination, operating cord, limiting member, and adjusting shell, where the operating cord is fixed at one end and free at the other, allowing the guide rollers to rotate and adjust the lamp's height upward or downward with the aid of ratchets and a controlling member to manage the rotation direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lamp is fixedly suspended on the ceiling, then the installation is simple and stable, but the height cannot be adjusted to match plant growth stages
Solution Approach 1:
The patent transforms the fixed suspension system into a dynamic adjustable system by introducing a guide roller combination that can rotate to change the lamp's height. The adjustable mechanism allows the lamp to adapt to different plant growth stages while maintaining operational simplicity through the cord-driven rotation system.
Solution Approach 2:
The guide roller combination is nested within the adjusting shell, creating a compact structure where the rotation mechanism is contained within the existing suspension framework. This nesting approach adds adjustability without significantly increasing external complexity or space requirements.
2Productivity
If the lamp remains at a fixed distance from the plant, then the structure is simple, but the light distribution becomes inefficient when plant height changes
Solution Approach 1:
The system enables self-adjustment through the operating cord mechanism, where the user can easily pull the cord to rotate the guide roller and adjust the lamp height. This self-service approach maintains ease of operation while significantly improving light supplementation efficiency by allowing the lamp to be repositioned according to plant growth.
3Illumination intensity
If the lamp is positioned too close to the plant, then light supplementation is intensive, but the plant may be burned by the light
Solution Approach 1:
The dynamic height adjustment capability allows the lamp to be moved to optimal distances from the plant, enabling intensive light supplementation when appropriate while preventing light burning by maintaining safe distances when needed. This resolves the contradiction by making light intensity control possible through position adjustment.
4Object-affected harmful factors
If the lamp is positioned too far from the plant, then light burning is avoided, but the loss of light increases and the plant may not receive sufficient light
Solution Approach 1:
The adjustable height mechanism enables the lamp to dynamically position itself at the optimal distance that balances light burning prevention with minimizing light loss. By allowing position adjustment, the system can maintain close proximity to the plant without causing damage, thereby reducing light energy loss while preventing harmful effects.
