Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bathing devices, such as bathtubs and shower systems, lack convenience and versatility in filling and maintaining optimal water levels, requiring manual intervention and frequent adjustments.
Innovation Solution
The development of showerhead systems integrated with float mechanisms and cylindrical rotary valves that allow for automatic filling of bathtubs to a predetermined level, using electronic sensors and mechanical controls to manage water flow, enabling hands-free operation and precise water level management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual water filling is used, then device complexity is reduced, but ease of operation deteriorates due to frequent manual intervention
Solution Approach 1:
The system employs automatic sensor detection and electronic control mechanisms that enable the bathing device to self-regulate water filling and shower function switching without requiring manual user intervention. The sensor automatically detects water levels and user presence, triggering appropriate responses through the control system.
Solution Approach 2:
The patent replaces manual mechanical operations with electronic sensing and control systems. Optical or capacitive sensors detect water levels and user presence, while electronic valves and pumps control water flow, eliminating the need for manual valve handling and mechanical water level monitoring.
2Ease of operation
If automatic water level control is implemented, then ease of operation improves, but loss of substance increases due to potential overfilling
Solution Approach 1:
The system incorporates continuous sensor monitoring that provides real-time feedback to the control system about water levels and user presence. When the sensor detects that the desired water level has been reached or when the user exits, the system automatically adjusts or stops water flow to prevent overfilling and waste.
Solution Approach 2:
The sensor system is designed to trigger water flow initiation at predetermined thresholds rather than waiting for complete manual filling. This partial action approach starts water flow early based on sensor detection, reducing the need for manual intervention while maintaining precise control through continuous monitoring.
3Adaptability or versatility
If multiple shower functions are integrated, then versatility improves, but device complexity increases
Solution Approach 1:
The patent integrates multiple shower functions including handheld shower, fixed shower, bath filling, and oral care capabilities within a single unified system. The electronic control system manages different functions through software control, allowing one physical system to perform multiple roles without requiring separate devices for each function.
Solution Approach 2:
The system employs dynamic function switching based on sensor detection and user interaction. The control system can dynamically adjust water flow distribution, spray patterns, and function activation based on real-time conditions, allowing the same hardware to adapt to different usage scenarios and user needs.
