Multi-Tiered Water Lantern Stability and Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in the difficulty of cleaning up water lanterns after events, as they often capsize in water, especially in windy conditions, and the inefficiency of using sloped ramps for deployment, which can lead to further tipping, and the need for lightweight designs to reduce shipping costs while maintaining stability.
Innovation Solution
A multi-tiered water lantern design featuring a lower and upper base with dowel rods and a curtain that can be expanded to surround the rods, providing stability and minimizing capsizing, along with an optional LED candle for visibility, and a method for controlled release and retrieval using a buoy system and ramp for efficient collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If water lanterns are made lightweight to reduce shipping costs, then shipping cost decreases, but stability and resistance to capsizing worsen
Solution Approach 1:
The lantern is divided into multiple compartments within the base structure, each contributing to overall stability. The multi-compartment design allows the lantern to maintain balance and resist capsizing while using lightweight materials, as each compartment can be optimized for both weight reduction and stability contribution.
Solution Approach 2:
The lantern base incorporates a weighted structure that provides counterbalance to the lightweight upper portions. This counterweight mechanism ensures that even though the overall lantern is lightweight for cost-effective shipping, the base provides sufficient stability to prevent capsizing in windy conditions.
2Productivity
If sloped ramps are used to slide lanterns into water, then deployment efficiency improves, but lantern stability worsens due to tipping
Solution Approach 1:
The lanterns are pre-assembled with their multi-compartment base structures before deployment. This preliminary configuration ensures that the stability-enhancing features are already in place, allowing the lanterns to be quickly slid down ramps without assembly delays while maintaining their anti-tipping structural integrity throughout the deployment process.
Solution Approach 2:
The lantern base features an asymmetric multi-compartment design with varying depths and configurations. This asymmetric structure creates a lower center of gravity and distributes weight unevenly to prevent tipping, allowing the lanterns to slide efficiently down ramps while maintaining stability upon water entry.
3Device complexity
If traditional single-tier lantern designs are used, then structural simplicity improves, but stability in windy conditions worsens
Solution Approach 1:
The base is segmented into multiple compartments rather than using a single hollow chamber. This segmentation creates a multi-tiered structure that increases stability in windy conditions by distributing forces across multiple sections, while the overall design remains relatively simple and does not require complex assembly procedures.

AI summary
A water lantern for floating on water with an LED candle is provided. The water lantern includes a base, dowel rods and a curtain. The base is designed with a tiered structure extending to a top surface with apertures formed therein to receive the dowel rods and a central recess for receiving the LED candle. The curtain is removably positioned over the base with the dowel rods maintaining the curtain in an expanded open position. The tiered structure of the base enhances the floating stability of the water lantern while also holding the LED candle above the water level to protect the LED candle from splashing water.
