Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single signal conversion type is used for vibration generation, then the system structure is simple, but the variety of physical sensations experienced by bathers is limited
Solution Approach 1:
The control unit dynamically switches between multiple signal conversion types (first and second conversion types) based on the input signal characteristics. This allows the vibration generation unit to adapt its output to provide different physical sensations (relaxing vs. impactful vibrations) without requiring multiple fixed vibration generation devices, thus resolving the contradiction between versatility and complexity.
Solution Approach 2:
The system changes the parameters of the operation signal (frequency components, amplitude characteristics) based on the selected signal conversion type. By adjusting these signal parameters according to the music tone and selected mode, the system provides varied physical sensations using a single vibration generation unit, avoiding the need for multiple devices.
2Adaptability or versatility
If the input signal is processed through multiple signal conversion types, then various vibration experiences are provided, but the control complexity increases
Solution Approach 1:
The control unit automatically selects the appropriate signal conversion type based on the music tone classification and user-selected mode, without requiring manual intervention. The system self-adjusts the signal processing parameters to match the input signal characteristics, making the complex control transparent to the user while providing diverse vibration experiences.
Solution Approach 2:
The control unit receives feedback about the input signal characteristics (music tone classification) and automatically adjusts the signal conversion type accordingly. This feedback mechanism allows the system to provide appropriate vibration experiences without requiring users to manually configure complex control parameters.
3Adaptability or versatility
If vibration generation is added to the bathtub system, then the physical sensation experience is enhanced, but the device complexity increases
Solution Approach 1:
The vibration generation unit is designed to perform multiple functions by responding to different signal conversion types. A single vibration generation unit can provide both relaxing vibrations and impactful vibrations by processing signals differently, eliminating the need for separate vibration generation devices for different experience types and reducing overall system complexity.

AI summary
The present invention provides a bathtub system (1) including a bathtub (2) configured to store hot or cold water therein; a vibration generation unit (10) configured to generate vibrations in the hot or cold water stored in the bathtub (2); and a control unit (30) configured to output an operation signal to the vibration generation unit (10). The control unit (30) has a plurality of control modes and is configured such that one of the plurality of control modes is selected in accordance with an input signal. In a case where a first control mode is selected, the control unit (30) generates the operation signal by changing the input signal in accordance with a first signal conversion type. In a case where a second control mode different from the first control mode is selected, the control unit (30) generates the operation signal by changing the input signal in accordance with a second signal conversion type different from the first signal conversion type.
