Bathing chair assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bathing devices do not effectively accommodate seated users, particularly elderly or physically disabled individuals, who have difficulty standing in showers, and lack integrated systems for pressurized water and soap delivery for efficient bathing.
Innovation Solution
A foraminous bathing chair with integrated conduits, a pump, and a soap reservoir that allows water and soap to be sprayed through its structure, connected to a shower head for increased pressure and soap mixing, enabling efficient bathing while seated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard shower is used, then water can be delivered to standing users, but seated users with mobility issues cannot be effectively accommodated
Solution Approach 1:
The shower system is segmented into multiple independent spray zones (backrest, seat, footrest, armrests) that can be individually activated. Each segment delivers water directly to the user's body area, enabling effective bathing for seated users without requiring them to stand or move to different positions.
Solution Approach 2:
The patent transitions from a vertical water delivery system (designed for standing users) to a horizontal/distributed spray system that covers multiple surfaces (backrest, seat, armrests, footrest). This dimensional change allows water to reach the user from multiple directions while they remain seated.
2Productivity
If manual soap application is used, then simple device structure is maintained, but bathing efficiency and hygiene are reduced
Solution Approach 1:
The patent merges the water delivery system with soap delivery by integrating soap reservoirs into the existing spray structure. Soap is delivered through the same conduits and spray nozzles that deliver water, creating a unified bathing system that applies both water and soap simultaneously to multiple body areas.
Solution Approach 2:
The spray system serves multiple functions: it delivers water for rinsing, soap for cleaning, and can be directed to different body areas. The same infrastructure (conduits, pumps, control system) handles both water and soap distribution, eliminating the need for separate manual application processes.
3Quantity of substance
If water pressure is low, then energy consumption is reduced, but water distribution thoroughness is insufficient
Solution Approach 1:
The system applies different pressure levels to different spray zones based on local needs. High-pressure spray is directed at areas requiring thorough cleaning (back, shoulders), while lower pressure is used for sensitive areas. The pump system adjusts pressure dynamically for each zone rather than applying uniform high pressure throughout.
Solution Approach 2:
The water pressure is made dynamic rather than static. The pump system can adjust pressure levels in real-time based on which spray zones are active and the specific bathing needs. This dynamic pressure control ensures adequate coverage while minimizing energy consumption when full pressure is not required.
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 solution provides a safe and effective bathing experience for seated users by ensuring thorough water and soap distribution, accommodating users with mobility issues and enhancing hygiene through adjustable pressure and soap integration.
Implementation Method 1
The chair is foraminous to pass water therethrough for bathing
Implementation Method 2
A pump is coupled to the chair to increase the pressure of the water being sprayed outwardly from the chair
Implementation Method 3
A pump is coupled to the chair to increase the pressure of the water being sprayed outwardly from the chair
Implementation Method 4
The reservoir releases the fluid soap into the chair to release a mixture of the fluid soap and the water for bathing

AI summary
A bathing chair assembly includes a chair that is positionable in a shower for a user to sit thereon. The chair is foraminous to pass water therethrough for bathing. A hose is fluidly coupled to the chair and the hose is fluid attachable to a shower head in the shower for receiving water therefrom. In this way the chair sprays the water for bathing the user when the user is sitting in the chair. A pump is coupled to the chair to increase the pressure of the water being sprayed outwardly from the chair. A reservoir is coupled to the chair and the reservoir contains a fluid soap. The reservoir releases the fluid soap into the chair to release a mixture of the fluid soap and the water for bathing.
