Solution Overview
Problem
Conventional electronic devices provide limited types of haptic effects primarily through vibration, lacking diversity in tactile feedback to users.
Innovation Solution
Incorporating haptic modules with Nitinol actuator wires that move weight members vertically or horizontally within the device to create distinct haptic effects, controlled by a processor based on device orientation and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibration inducing devices are used, then the device structure is simple, but the haptic effect diversity is limited
Solution Approach 1:
The haptic feedback system is divided into multiple independent haptic modules, each capable of producing different types of haptic effects through independent weight member movements in different orientations (vertical, horizontal, diagonal), allowing diverse haptic effects while maintaining modular simplicity
Solution Approach 2:
Each haptic module is designed as a multi-functional unit that can produce various haptic effects (taps, jolts, vibrations) by controlling the weight member's movement in different orientations, enabling a single module to replace multiple specialized components
2Adaptability or versatility
If vibration inducing devices are used, then the implementation is simple, but the haptic feedback types are limited
Solution Approach 1:
The haptic modules employ dynamic control of weight member movements, where the orientation and timing of movement are adjusted based on device orientation detection, enabling adaptive haptic feedback that responds to changing conditions without complex manual configuration
3Adaptability or versatility
If multiple haptic modules are added, then the haptic effect diversity increases, but the device complexity increases
Solution Approach 1:
Multiple haptic modules are integrated into a unified system controlled by a single processor that coordinates their operation based on device orientation, merging control logic to manage complexity while maintaining the versatility benefits of multiple modules
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a range of haptic effects, such as taps or jolts, enhancing user feedback and notifications by adapting to different orientations and scenarios, beyond traditional vibrations.
Implementation Method 1
The actuator wire may include a Nitinol material or other shape memory alloy, and when the actuator wire receives an electrical current, the actuator wire shortens

AI summary
Electronic devices and methods for creating various haptic effects. In one example, an electronic device may include a first haptic module for creating a first haptic effect, the first haptic module having a first weight member that selectively moves in a substantially vertical orientation relative to the first haptic module; a second haptic module for creating a second haptic effect, the second haptic module having a second weight member that selectively moves in a substantially horizontal orientation relative to the second haptic module; and a processor for controlling the first and second haptic modules. In one example, the processor selectively activates either the first haptic module or the second haptic module based on one or more events or conditions, such as the current orientation or position of the electronic device.
