Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current folding-screen mobile phones lack a three-dimensional vibration scheme, resulting in limited user experience due to single-dimensional and single-frequency vibration control.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-direction and single-frequency vibration control is used, then device complexity is reduced, but vibration richness and user experience deteriorate
Solution Approach 1:
The patent divides the vibration control system into multiple independent actuators (first actuator and second actuator) positioned at different locations and orientations. Each actuator can be controlled independently to generate vibrations in different directions and frequencies, transforming a single-dimensional vibration system into a multi-dimensional vibration system that provides richer haptic feedback while maintaining manageable complexity through modular actuator design.
Solution Approach 2:
The patent transitions from single-direction vibration to three-dimensional vibration by adding actuators oriented in different spatial dimensions. The first actuator provides vibration in one direction while the second actuator provides vibration in another direction, creating multi-directional vibration feedback that enhances user experience without requiring overly complex control algorithms.
2Ease of operation
If unified control manner is used for different holding forms, then control simplicity is improved, but adaptability to different user scenarios deteriorates
Solution Approach 1:
The patent implements dynamic vibration control that adapts to different holding types (one-handed vertical, one-handed horizontal, two-handed vertical, two-handed horizontal). The system dynamically selects which actuators to activate and what vibration patterns to generate based on the detected holding type, allowing the same device to provide optimized vibration feedback for various user scenarios without requiring multiple dedicated control modes or increasing operational complexity.
Solution Approach 2:
The patent creates a universal vibration control system that can handle multiple holding types and scenarios using the same actuator configuration. By designing the system to universally support different holding forms through software-based adaptation rather than hardware variations, the patent achieves both control simplicity and scenario adaptability within a single unified framework.

AI summary
A three-dimensional vibration control method includes: acquiring, when a trigger event is received, current state data of the electronic device and application software information associated with the trigger event; determining a holding type corresponding to the trigger event according to current state data and application software information; wherein holding type includes fully folded vertical one-handed holding, fully folded horizontal two-handed holding, half folded horizontal two-handed holding, fully unfolded vertical two-handed holding, and fully unfolded horizontal two-handed holding; determining a corresponding vibration scheme according to the holding type; and controlling the actuators to enter a vibration operating state correspondingly based on the vibration scheme. After a type of holding a device by a user is determined, a vibration scheme of a corresponding type is adopted, so as to control the corresponding actuators for vibration feedback in real time to make three-dimensional vibration response to different trigger events, which improves vibration experience.
