Portable Beach Chair With Built-In Misting Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable beach chairs do not effectively provide cooling for sunbathers without requiring access to a water source, as they lack a built-in refillable water reservoir and misting system for direct cooling.
Innovation Solution
A portable beach chair equipped with a refillable water reservoir and a misting showerhead that directs a cooling water flow towards the user, eliminating the need to access a hose or waterbody for cooling, featuring a hingedly connected back support, adjustable showerhead, and foldable design for portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a portable beach chair is equipped with a built-in water reservoir and misting system, then cooling effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single portable beach chair system: the chair structure, water reservoir, pump mechanism, and misting nozzles are integrated into one unified device. This merging allows the chair to simultaneously provide seating support and active cooling through mist generation, resolving the contradiction by making the cooling system portable and self-contained while maintaining reasonable complexity through functional integration.
Solution Approach 2:
The beach chair is designed to be self-sufficient with an onboard water reservoir and pump system that operates independently without requiring external water sources or power during use. The system draws water from its own reservoir, pumps it through the misting nozzles, and recycles condensate back into the reservoir, creating a self-service cooling system that improves cooling effectiveness while avoiding the complexity of external connections.
2Temperature
If a refillable water reservoir is added to the beach chair, then cooling capability is improved, but weight increases
Solution Approach 1:
The patent employs parameter changes by using a refillable water reservoir that can be filled with water of varying temperatures. By changing the temperature parameter of the water (using cold or ice-cold water), the system achieves enhanced cooling capability without needing to increase the physical mass of the cooling mechanism itself, thus improving cooling capability while managing weight through thermal parameter optimization rather than mass addition.
3Temperature
If a misting showerhead is positioned above the back support portion, then cooling coverage is improved, but device complexity increases
Solution Approach 1:
The misting system is segmented into multiple nozzles positioned at different locations: one showerhead above the back support portion for upper body cooling, and additional nozzles near the seat for lower body cooling. This segmentation provides comprehensive cooling coverage across the entire body surface while managing device complexity by distributing the misting function across multiple simple nozzle components rather than one complex centralized system.

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 chair provides effective cooling for sunbathers by using a refillable water reservoir and misting showerhead, ensuring comfort without the need for external water sources, while being lightweight, durable, and easy to transport.

AI summary
A portable beach chair for cooling a person while relaxing or basking in a warm environment is provided. The portable beach chair comprises a chair having a body support portion and a back support portion with the back support portion hingedly connected to the body support portion and releasably securable in a desired angular position. A water reservoir secured to the back support portion holds a predetermined amount of water. A showerhead is fluidly connected to the water reservoir with the showerhead positioned above the back support portion and directing a water flow from the water reservoir in a general direction toward both the body support portion and the back support portion. Upon introducing water through the showerhead from the water reservoir, the water flow through the showerhead cools the person thereby eliminating any need for the person to access a hose or go into a waterbody to cool off.
