Solution Overview
Problem
Conventional electronic devices, such as notebook computers, lack an efficient and intuitive input mechanism that provides clear feedback on the strength of user input, leading to potential misjudgment and reduced usability during operation.
Innovation Solution
An electronic device design incorporating a detachable input element with a pressure sensing layer, a vibration layer, and a transmission layer, where the pressure sensing layer generates signals based on force strength, causing the vibration layer to vibrate at varying intensities, and the transmission layer ensures these vibrations are felt by the user through the protective layer, enhancing feedback and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional input devices (keyboard/mouse) are used, then basic input functionality is provided, but clear feedback on input strength is not provided leading to potential misjudgment
Solution Approach 1:
The patent implements a feedback mechanism where the vibration layer generates tactile feedback proportional to the pressure applied by the user. The pressure sensing layer detects input strength, and this information is converted into corresponding vibration intensity through the vibration layer, providing immediate tactile feedback to the user about their input strength.
Solution Approach 2:
The patent replaces traditional mechanical feedback mechanisms with a vibration-based system. Instead of relying on mechanical resistance or physical feedback from keys and buttons, the system uses electromagnetic vibration generated by the vibration layer to provide tactile feedback, enabling more precise and controllable input strength indication.
2Reliability
If the input element is made detachable for safe keeping, then portability and safety are improved, but structural complexity increases
Solution Approach 1:
The patent divides the electronic device into separable components, specifically making the input element detachable from the main body. This segmentation allows the input element to be removed for safe keeping or transport, while the main body retains other essential functions. The detachable design is implemented through separate mounting structures that allow easy attachment and detachment.
3Measurement precision
If the vibration layer vibrates at varying intensities to indicate force strength, then input feedback precision is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by adjusting the vibration intensity to match only the necessary feedback level. The vibration layer operates at varying intensities based on the detected pressure, providing sufficient feedback for input strength indication without maintaining maximum vibration continuously. This reduces energy consumption while preserving measurement precision.
