Portable Bathtub With Removable Volume Block for Water-Saving Baths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bathtubs require large amounts of hot water, leading to wastage and energy inefficiency, making it difficult for families without a bathtub to enjoy a hot bath while also being environmentally unsustainable.
Innovation Solution
A portable, water and energy-saving bathtub design featuring a collapsible container with a flashboard gate, a reducing-volume-chunk, and a locking-releasing-device that allows for efficient use of hot water, easy drainage, and portability, enabling hot baths in small spaces or outdoors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a conventional bathtub is used, then people can enjoy a hot bath, but large amount of hot water is consumed leading to water and energy waste
Solution Approach 1:
The bathtub is divided into a container body and a reducing-volume-chunk that can be separated. The reducing-volume-chunk is removed before bathing to create sufficient space for the bather, then inserted during bathing to reduce water consumption. This segmentation allows the tub to serve dual purposes: providing full bathing space when needed and reducing water capacity when water conservation is desired.
Solution Approach 2:
The bathtub design incorporates a removable reducing-volume-chunk that dynamically changes the water-holding capacity of the container. The chunk can be inserted or removed based on whether water conservation is prioritized or full bathing experience is needed, making the water consumption adjustable rather than fixed.
2Quantity of substance
If a portable bathtub with reducing-volume-chunk is used, then water consumption is reduced, but the device complexity increases due to additional components
Solution Approach 1:
The reducing-volume-chunk is designed to be nested within the container body when not in use. The chunk fits inside the container, allowing compact storage and easy portability. This nesting approach minimizes the increased complexity by keeping the additional component space-efficient and integrated into the overall structure.
3Quantity of substance
If the reducing-volume-chunk is inserted in the container, then water consumption is reduced, but the available space for the bather is reduced

The reducing-volume-chunk is removed before bathing to create sufficient space for the bather, then inserted during bathing to reduce water consumption.

4Weight of moving object
If a portable bathtub design is used, then portability and water saving are improved, but the ease of drainage may be worsened
Solution Approach 1:
The reducing-volume-chunk is extracted or removed from the container after the bathing process is complete. This extraction action facilitates drainage by opening up the container space and allowing water to be easily emptied. The same chunk that was inserted to reduce water consumption during bathing is now removed to restore full drainage capability, thus resolving the contradiction between water saving during use and drainage convenience after use.

AI summary
A portable water and energy saving bathtub used in a shower room or a bathtub comprises a body liking an opened container, a step on the bottom is located beside the end wall. The other end is a flashboard gate, which includes a groove on inner faces of the container, the flashboard capable of moving is inserted into the groove until to a bottom of the groove, a water seal ring is set between the groove and the flashboard. A reducing-volume-chunk likes a cuboid has two legs sitting on the side walls of container, therefore, the reducing-volume-chunk is hanged in the container. A locking-releasing-device locks or releases the rock for the reducing-volume-chunk with the container.
