Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing therapy devices use complex control systems for frequency selection and treatment protocols, then treatment customization capability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The device is divided into functionally independent modules: a frequency generator unit with fixed frequency outputs, a separate control device for timing control, and an energy store. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining treatment customization through modular configuration.
Solution Approach 2:
The control device implements periodic activation and deactivation of the AC voltage source through simple timing control, creating treatment cycles without requiring complex continuous adjustment mechanisms. This periodic approach simplifies the control system while enabling customizable treatment protocols through variable cycle timing.
2Manufacturing precision
If existing therapy devices require continuous monitoring and adjustment during treatment, then treatment precision is improved, but ease of operation deteriorates
Solution Approach 1:
The frequency generator unit is pre-configured with specific frequency outputs suitable for different treatment conditions. The control device is pre-programmed with treatment cycle timings. This preliminary configuration eliminates the need for complex real-time adjustments during treatment, maintaining precision while simplifying operation.
Solution Approach 2:
The system automatically executes pre-programmed treatment cycles with fixed frequency outputs and timing sequences. The control device autonomously manages the activation and deactivation cycles without requiring continuous user intervention or monitoring, thereby maintaining treatment precision while significantly improving ease of operation.
3Reliability
If therapy devices use multiple frequency generators for comprehensive treatment, then treatment effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The frequency generator unit is designed to provide multiple fixed frequency outputs from a single device, enabling it to serve multiple treatment functions. This universal approach allows one frequency generator to replace what would traditionally require multiple specialized generators, maintaining treatment effectiveness while reducing overall system complexity and cost.

AI summary
A therapeutic device (1) for treating preferably human patients (4) comprises at least two electrodes (3, 6) that can be connected to a patient (4). The therapeutic device includes an alternating voltage source (2) that applies an alternating voltage to the two electrodes (3). The therapeutic device (1) includes a control device (5) that is connected to the alternating voltage source (2). The control device (5) is configured to periodically activate the alternating voltage source (2) for a first period (100), so that the electrodes (3, 6) are supplied with an alternating voltage that can be transmitted to the patient (4) for treatment. The control device (5) is further configured to periodically deactivate the alternating voltage source (2) for a second period (200), so that at least one of the electrodes (3, 6) is grounded during the second period (200) to allow charge to dissipate from the patient (4).
