Portable Golf Lighting with Reflective Cover and Carrying Rack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems for golf putting greens are expensive, require extensive infrastructure, and often cause light pollution, while existing portable solutions like illuminated cups and flagstick lights are limited in coverage and maintenance-intensive.
Innovation Solution
A portable lighting apparatus with a shaft, lighting assembly, and base that can be easily installed in a golf hole, featuring a rechargeable battery, solar cells, and a reflective cover to direct light, along with a carrying rack for easy transportation and charging, providing targeted illumination without permanent wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional overhead lighting systems are used, then illumination coverage is improved, but infrastructure cost and complexity increase
Solution Approach 1:
The lighting system is segmented into individual portable units that can be independently deployed in golf holes, eliminating the need for centralized overhead infrastructure. Each unit contains its own light source, battery, and reflective cover, allowing distributed illumination without complex wiring or support structures.
Solution Approach 2:
The lighting units are self-powered through rechargeable batteries that can be charged via solar panels or external power sources. The units autonomously provide illumination when placed in golf holes, requiring no external infrastructure, wiring, or maintenance during operation.
2Illumination intensity
If conventional overhead lighting systems are used, then illumination coverage is improved, but light pollution increases
Solution Approach 1:
The lighting system provides localized illumination focused on specific golf holes and surrounding areas rather than broad overhead coverage. The reflective covers direct light downward and outward from each unit, concentrating illumination where needed while minimizing stray light and pollution in surrounding areas.
3Ease of operation
If illuminated cups are used, then portability is improved, but maintenance requirement increases
Solution Approach 1:
The lighting components (bulb, battery, reflective cover) are merged into a single integrated unit that remains in the golf hole during use. This eliminates the need to repeatedly remove, recharge, and replace separate illuminated cups, significantly reducing daily maintenance while maintaining portability.
4Ease of operation
If flagstick lights are used, then portability is improved, but light direction control worsens
Solution Approach 1:
The reflective covers are specifically designed to direct light downward and outward toward the golf hole and surrounding area, preventing light from traveling upward into golfers' eyes. This localized light direction control eliminates the harmful effect of light entering players' vision while maintaining the benefits of portable flagstick-mounted lighting.
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 portable lighting apparatus offers efficient, maintenance-free illumination for golf putting greens, reducing costs and light pollution, while the carrying rack facilitates easy deployment and recharging, enhancing golfing experience during twilight and nighttime practices.
Implementation Method 1
The lighting assembly may also include at least one solar cell coupled to the rechargeable battery to recharge the rechargeable battery
Implementation Method 2
An inner surface of the cover facing the at least one bulb is adapted to reflect light emitted from the at least one bulb
