Solution Overview
Problem
Existing bathtub systems do not provide a finely tuned comfort to users by combining hot/cool water stream generation and vibration in a coordinated manner, leading to potential interference between the two stimuli.
Innovation Solution
A bathtub system that includes a hot/cool water stream generating unit to create a hot or cool water stream within pooled water and a vibration generating unit to create vibrations in the pooled water, with a controlling unit to coordinate their operations and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If both hot/cool water stream generation and vibration generation are operated simultaneously, then comprehensive user comfort is improved, but the two stimuli may interfere with each other reducing effectiveness
Solution Approach 1:
The system dynamically adjusts the operation timing of the hot/cool water stream generating unit and vibration generating unit based on coordinated control. The control unit switches between simultaneous operation mode (for comprehensive comfort) and sequential operation mode (for preventing interference), making the system adaptive to different usage scenarios and maintaining reliability while improving versatility.
Solution Approach 2:
The system employs periodic alternation between simultaneous and sequential operation modes of the two generating units. By controlling the timing and duration of each mode, the system achieves comprehensive user comfort while preventing stimulus interference, effectively resolving the contradiction between versatility and reliability.
2Force
If hot/cool water is supplied vigorously to generate streams, then strong water pressure stimulation is achieved, but energy consumption increases
Solution Approach 1:
The system changes the operational parameters of the hot/cool water stream generating unit by coordinating it with the vibration generating unit. Instead of continuously operating at high intensity, the system adjusts the water supply intensity and timing based on when vibration stimulation is applied, achieving strong water pressure stimulation when needed while reducing energy consumption during vibration-only phases.
3Ease of operation
If vibration is generated in pooled water, then delicate surface stimulation is provided, but the vibration may interfere with hot/cool water stream action
Solution Approach 1:
The control unit dynamically manages the operation timing of both generating units, switching between simultaneous and sequential modes. This dynamic control ensures that vibration provides delicate surface stimulation while preventing interference with hot/cool water stream action through coordinated timing adjustments.
Solution Approach 2:
The system employs coordinated control that monitors the operation state of both generating units and adjusts their timing accordingly. This feedback mechanism prevents vibration from interfering with hot/cool water stream action while maintaining the delicate surface stimulation benefit, resolving the contradiction between ease of operation and reliability.
