Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game apparatuses can only impart monotonous vibrations, limiting the user's experience to vibrations sourced near the vibrators, failing to provide unconventional and immersive sensations.
Innovation Solution
A vibration generation system comprising physically separated first and second vibration output apparatuses, with processors generating and controlling vibration signals to create the illusion of a single vibration source between them, allowing for adjustable intensity and movement of the perceived vibration source, along with synchronized vibration and sound output to enhance realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vibrator is used in a game apparatus, then the device structure is simple, but the vibration sensation is monotonous and limited to sources near the vibrator
Solution Approach 1:
The vibration output apparatus is divided into multiple independent vibration units (first vibration unit and second vibration unit) that can be controlled separately. This segmentation allows each unit to contribute to creating different vibration sensations, enabling the system to produce diverse vibration patterns and perceived source positions without requiring a completely new device architecture.
2Adaptability or versatility
If multiple vibration units are used to create diverse vibrations, then the vibration sensation becomes more varied, but the device complexity increases
Solution Approach 1:
Multiple vibration units are combined within a single vibration output apparatus, allowing them to work together to create a unified vibration sensation. The control unit coordinates the vibration units to produce the illusion of a single vibration source at different positions, merging their individual outputs into a cohesive tactile experience that enhances versatility without proportionally increasing perceived device complexity.
Solution Approach 2:
The system changes the vibration parameters (intensity, frequency, phase) of each vibration unit dynamically to create different perceived vibration source positions. By adjusting these parameters, the control unit can make the user perceive vibrations originating from different locations along the apparatus, providing versatile vibration control without adding physical complexity to the hardware structure.
3Adaptability or versatility
If vibration units are physically separated, then unconventional vibration perceptions can be achieved, but the synchronization control becomes more difficult
Solution Approach 1:
The control unit implements feedback control to maintain precise synchronization between physically separated vibration units. By monitoring the vibration state of each unit and adjusting their operation accordingly, the system can accurately control the perceived vibration source position and maintain coordination between distributed vibration sources, overcoming the challenges of physical separation.

AI summary
At least a first vibration output apparatus and a second vibration output apparatus used while physically separated from the first vibration output apparatus are included. The first vibration output apparatus includes a first vibration unit. The second vibration output apparatus includes a second vibration unit. It is possible to output a first vibration signal and a second vibration signal for, by changing a ratio of intensities of vibrating the first vibration unit and the second vibration unit, causing a user to perceive a single vibration source between the first vibration output apparatus and the second vibration output apparatus.
