Dual-Motor Vibration Layout for Electronic Equipment Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single motor arrangements in electronic equipment often result in a balance point, leading to weak vibrations and a diminished user experience, especially when held with both hands.
Innovation Solution
The use of two motors, one at a designated location on the top and one at a designated location on the bottom of the electronic equipment, connected by a drive module that can drive them to vibrate independently or synchronously, avoiding the balance point and increasing vibration amplitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor is arranged in electronic equipment, then the device complexity is reduced, but the vibration amplitude and user experience deteriorate due to the presence of a balance point
Solution Approach 1:
The patent divides the single motor system into multiple motors (first motor and second motor) positioned at different locations. This segmentation eliminates the balance point problem by distributing vibration sources, thereby increasing overall vibration amplitude and improving user experience while maintaining reasonable device complexity.
2Ease of manufacture
If a single motor is used at the top or bottom, then the manufacturing cost is reduced, but the vibrational prompt effect weakens when held with both hands
Solution Approach 1:
The patent applies local quality by positioning motors at specific locations (top and bottom) with different vibration characteristics. The first motor generates strong vibration at the top while the second motor compensates at the bottom, ensuring consistent vibrational prompt effect throughout the device when held with both hands.
3Force
If multiple motors are arranged at different locations, then the vibration amplitude and user experience are improved, but the device complexity increases
Solution Approach 1:
The patent merges the control of multiple motors through a unified control module that coordinates the first and second motors. This integration allows the system to achieve enhanced vibration amplitude through multiple motors while managing complexity through centralized control logic.

AI summary
Electronic equipment (100) includes a center frame (40), a first motor (20), a second motor (30), and a drive module. The first motor (20) and the second motor (30) are fixed respectively at a first designated location and a second designated location of the center frame (40). The drive module is electrically connected respectively to the first motor (20) and the second motor (30). The drive module is adapted to driving, according to a control signal, the first motor (20) or the second motor (30) to vibrate independently, or driving the first motor (20) and the second motor (30) to vibrate synchronously.
