Resilient Bulb Holder for Hydroponic Drum Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating drum hydroponic systems face challenges in maintaining consistent light intensity for young plants and managing heat buildup from light sources, as existing solutions do not allow for easy lamp replacement or adequate ventilation.
Innovation Solution
A bulb holder with a resilient ring member and angled arms that can be compressed to fit within a transparent tube, providing easy lamp replacement and maximizing ventilation to mitigate heat buildup, while being made from materials like aluminum or stainless steel to withstand the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light source is placed at a fixed distance from the plants to ensure adequate space for plant growth, then the light intensity is sufficient for fully grown plants, but the light intensity becomes insufficient for young plants
Solution Approach 1:
The patent implements a movable light source that can be adjusted along the rotation axis of the drum. This dynamic positioning allows the light source to move closer to young plants for higher intensity and farther from fully grown plants, resolving the contradiction between maintaining adequate space and providing sufficient light intensity at different growth stages
2Reliability
If the bulb is incased in a transparent tube for protection, then the bulb is protected from damage, but heat build up occurs due to insufficient ventilation
Solution Approach 1:
The patent replaces the solid transparent tube with a mesh screen enclosure. This flexible-like structure provides protection while allowing maximum ventilation through its open mesh design, enabling heat dissipation while maintaining bulb protection
Solution Approach 2:
The mesh screen acts as a porous material that allows air flow through the enclosure. The porous structure provides numerous pathways for ventilation, effectively removing heat from the bulb while maintaining protective enclosure
3Use of energy by moving object
If a rotating drum system is used to maintain constant light distance, then energy efficiency is improved, but the complexity of the system increases
Solution Approach 1:
The patent integrates the light source adjustment mechanism into the existing drum rotation system. The light source is mounted on the drum itself, allowing it to move with the rotation while maintaining adjustable positioning. This multi-functional integration reduces overall system complexity while preserving energy efficiency benefits
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bulb holder ensures consistent light intensity by allowing easy lamp interchange and reduces heat buildup through enhanced ventilation, improving plant growth conditions in rotary hydroponic systems.
Implementation Method 1
a ring member formed of a resilient material, the ring member having first and second ends, the first and second ends being biased away from each other to a position where the first and second ends are spaced apart, the first and second ends being movable towards each other to thereby diminish the size of the ring

AI summary
A bulb holder which comprises a bulb socket and a housing, a ring member formed of a resilient material, the ring member having first and second ends biased away from each other to a position where the first and second ends are spaced apart, the ends being movable towards each other to thereby diminish the size of the ring, and first and second arms interconnecting the ring member and the socket housing. The bulb holder permits circulation of air throughout a transparent tube in which the bulb is mounted.
