Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the vibrator adjusts vibration strength by changing electrical energy and frequency, then the vibration effect can be varied, but the output strength becomes inconsistent and varies with electrical energy and frequency

Engineering Contradiction:

Improvevibration effect variationVSAvoidoutput strength consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a strength feedback function where the sensor detects the actual vibration strength and feeds this information back to the processor. The processor then adjusts the driving signal to compensate for deviations, ensuring the output strength matches the target value regardless of electrical energy or frequency changes.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically changes multiple parameters (voltage, frequency, duty cycle) of the driving signal based on feedback from the strength sensor. This multi-parameter adjustment allows the system to maintain consistent output strength while adapting to different operating conditions.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If hardware elements are adjusted to change vibration strength, then the vibration magnitude can be controlled, but software updates cannot be applied to previous adjustments

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces physical hardware adjustments with a software-based strength feedback control system. The processor dynamically adjusts vibration strength through software-controlled driving signals based on sensor feedback, eliminating the need for physical hardware modifications and enabling software updates to take effect immediately.

AI summary

A control device and a correcting method of a control device with a strength feedback function are disclosed. The control device includes a vibrator, a driver, a strength sensor, and a processor. In correction procedures, the driver provides a driving signal with a plurality of different setting voltage values respectively to the vibrator. In each correction procedure, the driver adjusts a frequency of the driving signal to setting frequency values by time division. In the correction procedures, the strength sensor senses a strength generated by a vibration of the vibrator to obtain strength sensing information respectively corresponding to the setting voltage values. The processor analyzes the strength sensing information, the setting frequency values, and the setting voltage values to obtain relationship information between the setting frequency values and the setting voltage values corresponding to each strength sensing information.
