Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses, such as digital cameras, experience variations in tactile sensation due to the presence or absence and type of accessories attached, affecting the user's feedback from vibration devices.
Innovation Solution
The implementation of a controlling unit that adjusts vibration parameters of vibration devices on both the electronic apparatus and detachable accessories to match the type of accessory attached, ensuring a consistent tactile sensation effect.

Engineering Contradiction Analysis
1Object-generated harmful factors
If a vibration device is used to generate tactile sensation instead of a mechanical mechanism, then the click sound is eliminated and various tactile sensations can be reproduced, but the tactile sensation effect varies depending on the type of accessory attached
Solution Approach 1:
The vibration device's operating parameters (amplitude, frequency, duration) are made dynamically adjustable based on the detected accessory type. The control unit modifies the vibration characteristics in real-time to compensate for different accessory properties, ensuring consistent tactile sensation across various accessories while maintaining the benefit of sound elimination.
Solution Approach 2:
The system changes physical parameters of the vibration device (driving frequency, amplitude, pulse width modulation) according to the accessory type. By adjusting these parameters, the system adapts the tactile feedback to match user expectations for different accessory configurations, resolving the inconsistency problem.
2Device complexity
If the vibration device operates with fixed vibration parameters, then the control is simple, but the tactile sensation effect differs when accessories are attached or detached
Solution Approach 1:
The control unit receives feedback about the accessory type through detection mechanisms (optical sensors, mechanical switches, or communication interfaces) and automatically adjusts the vibration parameters accordingly. This closed-loop feedback system maintains tactile sensation consistency without requiring manual intervention from the user.
Solution Approach 2:
The system performs self-adjustment by automatically detecting the accessory type and modifying its own operating parameters. The vibration device is controlled autonomously based on the detected configuration, eliminating the need for user intervention while ensuring optimal tactile feedback for each accessory type.
