Solution Overview
Problem
Conventional mock force sensation devices for smartphones and information devices lack directional control and flexibility, requiring separate development for each device, which is costly and time-consuming, and struggle to clearly present force sensations due to limited degrees of freedom.
Innovation Solution
A mock force sensation presenting device with a case, holder, and multiple modules that can present force sensations in various directions, including translations and rotations, integrated with information devices for easy communication and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vibration device is used for tactile stimulation in smartphones and tablets, then tactile feedback can be provided, but directional force sensation cannot be presented
Solution Approach 1:
The device segments the force generation function into multiple independent mock force sensation presenting modules, each capable of generating force in specific directions. This allows the system to provide both general tactile feedback and directional force sensation by coordinating multiple segmented modules.
Solution Approach 2:
The mock force sensation presenting modules are designed with multi-functionality, capable of operating in both vibration mode (for general tactile feedback) and directional force generation mode. This universal design allows a single device to satisfy both tactile feedback requirements and directional force sensation needs.
2Reliability
If a dedicated mock force sensation presenting device is developed for each information device, then clear force sensation can be presented, but development cost and time increase significantly
Solution Approach 1:
The mock force sensation presenting device is designed as a universal solution that can be integrated with various types of information devices (smartphones, tablets, etc.). The standardized interface and multi-directional capability allow a single device design to serve multiple platforms, reducing development time and cost while maintaining force sensation clarity.
Solution Approach 2:
The device incorporates dynamically controllable modules that can adjust their operation mode and direction based on the specific application requirements. This dynamic adaptability allows the same hardware to optimize force sensation presentation for different information devices without requiring dedicated development for each platform.
3Reliability
If a dedicated mock force sensation presenting device is developed for each information device, then specific force sensation requirements can be met, but the device lacks flexibility to change degrees of freedom and directions
Solution Approach 1:
The force generation system is divided into multiple independent modules, each capable of operating in specific directions. This segmentation provides degrees of freedom by allowing selective activation and coordination of different modules to achieve various force sensation directions and patterns, enhancing adaptability while maintaining accuracy.
Solution Approach 2:
The mock force sensation presenting modules are designed with dynamic control capabilities, allowing real-time adjustment of operation modes, directions, and intensity. This dynamic nature enables the device to adapt to different force sensation requirements across various information devices without sacrificing force presentation accuracy.
4Adaptability or versatility
If multiple mock force sensation presenting modules are used, then degrees of freedom for force direction are increased, but device complexity increases
Solution Approach 1:
Multiple mock force sensation presenting modules are merged into a single integrated holder structure that can be attached to the information device as one unit. This merging approach increases force direction flexibility through multiple modules while managing integration complexity by providing a unified mounting interface and coordinated control system.
