A shower tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower trays, particularly ceramic and polymeric synthetic ones, suffer from discomfort due to hardness, slipperiness, inability to adapt to geometry, fragility, and issues with water leakage and drainage, while foamed polymer trays lack softness and adjustability.
Innovation Solution
A shower tray comprising a rigid polymeric resin core with added mineral content and a polyurethane rubber covering, allowing for on-site cutting and drainage slopes, providing a soft surface and adjustable geometry without compromising sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a ceramic shower tray is used, then the tray is hard and durable, but the user feels uncomfortable and the surface is slippery
Solution Approach 1:
The shower tray combines a rigid polymeric core with a soft polymeric covering layer, creating a composite structure that provides both structural strength and comfortable, non-slip surface properties for user safety and comfort
2Duration of action of stationary object
If a ceramic shower tray is used, then the tray is durable, but it cannot be adapted to any geometry and modifications require cubicle changes
Solution Approach 1:
The shower tray is divided into a rigid core structure and a separate soft covering layer that can be independently cut and shaped, allowing geometric adaptations to be made in the covering without affecting the structural integrity of the core
3Ease of operation
If a polymeric synthetic shower tray is used, then the tray is soft and flexible, but deformations occur in the drainage zone causing water leaks
Solution Approach 1:
The composite structure uses a rigid polymeric core to maintain the shape and structural integrity of the drainage zone, preventing deformations and ensuring reliable sealing, while the soft polymeric covering provides comfort without compromising drainage functionality
4Weight of moving object
If a foamed polymer shower tray is used, then the tray is lightweight, but it lacks softness and cannot be adjusted by cutting
Solution Approach 1:
The shower tray separates the structural function (rigid core that can be cut and shaped) from the comfort function (soft covering), allowing both adaptability through cutting and softness for user comfort while maintaining a lightweight construction
