Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hardware devices for authentication are prone to damage due to fragile or movable parts, such as biometric sensors and buttons, which can lead to errors and malfunctions, especially under environmental influences like vibrations or unstable conditions.
Innovation Solution
A device for authorizing computer programs that uses a solid protection housing made of rigid material, such as metal, and detects tapping gestures internally using a 3D microelectromechanical system (3D MEMS) or an accelerometer, eliminating the need for external sensors or buttons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric sensors or buttons are arranged on the housing for user interaction, then ease of operation is improved, but reliability deteriorates due to damage from environmental influences and mechanical stress
Solution Approach 1:
The patent replaces mechanical interaction components (buttons, switches, biometric sensors on housing) with contactless detection methods. The housing itself becomes a detection element for contactless gestures such as tapping or knocking, eliminating the need for fragile mechanical parts while maintaining ease of operation. This substitution resolves the contradiction by removing the source of mechanical damage while preserving user interaction capability.
2Ease of operation
If fragile biometric sensors are used on the housing, then ease of operation is improved, but manufacturing precision requirements increase due to sensitivity to environmental factors
Solution Approach 1:
The patent eliminates fragile biometric sensors from the housing by implementing contactless detection mechanisms. The housing structure itself is utilized as a transducer for detecting contactless gestures, thereby removing the need for precise sensor placement and protection while maintaining authentication functionality. This resolves the manufacturing precision issue by eliminating the sensitive components that required precise integration.
3Ease of operation
If movable parts like buttons are included in the housing, then ease of operation is improved, but reliability deteriorates due to mechanical damage from repeated use
Solution Approach 1:
The patent replaces movable mechanical parts (buttons, switches) with contactless gesture detection. The housing acts as a mechanical transducer that detects contactless tapping or knocking gestures through vibration or acceleration sensors, eliminating wear and mechanical failure while preserving user activation capability. This resolves the contradiction by removing the mechanical wear source while maintaining operational ease.
