Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massage devices for sexual stimulation face challenges in maintaining consistent intensity due to increased electrical power consumption caused by mechanical loading of the electric motor unit, leading to a decrease in mechanical power and massage movement intensity.
Innovation Solution
A control arrangement that measures the intensity of movement and/or deformation connected to the electric motor unit, compares it with a reference power consumption, and adjusts the massage intensity by modifying the operating parameters such as voltage or pulse width modulation to match user needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electric motor unit is mechanically loaded during massage, then the current consumption increases, but the mechanical power generated decreases
Solution Approach 1:
The control arrangement continuously monitors the electrical power consumption of the electric motor unit and uses this feedback to adjust the operating parameters. When mechanical loading increases power consumption, the system detects this change and automatically compensates by adjusting voltage or current to maintain mechanical power output, thus resolving the contradiction between increasing energy consumption and decreasing mechanical power.
Solution Approach 2:
The system changes operating parameters (voltage, current, frequency) of the electric motor unit based on detected power consumption levels. By dynamically adjusting these parameters, the control arrangement optimizes the balance between electrical power input and mechanical power output, ensuring that mechanical power is maintained even when mechanical loading increases electrical consumption.
2Power
If the intensity of massage movement is increased, then the mechanical power generated increases, but the electrical power consumption increases leading to conversion losses
Solution Approach 1:
The control arrangement monitors electrical power consumption and mechanical power output in real-time, using this feedback to optimize the conversion efficiency. When conversion losses increase, the system adjusts operating parameters to restore optimal efficiency, thereby maintaining mechanical power while minimizing energy losses during the electrical-to-mechanical energy conversion process.
Solution Approach 2:
The control arrangement periodically measures and evaluates the power consumption and adjusts operating parameters in cycles. This periodic optimization allows the system to maintain high mechanical power output while continuously minimizing conversion losses by adjusting to the most efficient operating point at each measurement interval.
3Use of energy by moving object
If the current consumption increases during massage, then the electrical power consumption increases, but the operating voltage remains the same causing loss of massage intensity
Solution Approach 1:
The control arrangement detects increases in current consumption during massage and uses this feedback to automatically adjust operating parameters such as voltage or frequency. This compensation mechanism ensures that massage intensity is maintained despite variations in current consumption, providing consistent user experience without manual intervention.
Solution Approach 2:
The system dynamically adjusts operating parameters in response to changing load conditions. When current consumption increases, the control arrangement modifies voltage, current, or frequency settings to maintain optimal massage intensity, making the system adaptable to varying mechanical loading conditions during use.
