Electronic Lock Haptic Feedback Using Electromagnetic Diaphragm Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic locks with touch panels lack clear tactile feedback, making it uncertain for users to confirm key selection.
Innovation Solution
An electronic lock design incorporating a diaphragm, inductor member, and magnetic member, where the circuit board distributes electric currents to the inductor member, causing the magnetic member to alternately attract and push the inductor member, thereby vibrating the diaphragm to provide haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional touch panel is used in the electronic lock, then the device structure is simple, but the user cannot confirm key selection through tactile feedback
Solution Approach 1:
The patent employs a vibration module comprising a driving element (electromagnetic actuator) and a diaphragm that vibrates upon receiving driving signals, generating tactile feedback through mechanical vibration to enable users to confirm key selection through touch sensation
Solution Approach 2:
The diaphragm serves as an intermediary component that transmits the vibration generated by the driving element to the user's finger, providing tactile feedback without requiring direct contact between the user and the electromagnetic actuator
2Loss of information
If haptic feedback components are added to provide tactile feedback, then user confirmation capability is improved, but the device complexity increases
Solution Approach 1:
The vibration module is integrated within the housing structure, with the driving element and diaphragm arranged in a compact configuration that combines multiple functions (vibration generation, tactile feedback delivery) into a single integrated assembly
Solution Approach 2:
The diaphragm serves multiple functions: it acts as a vibration transmission surface for haptic feedback, maintains the structural integrity of the input panel, and provides a smooth touch surface for user interaction

AI summary
An electronic lock capable of offering haptic feedback includes an input panel, a circuit board, at least one inductor member, at least one magnetic member, and at least one diaphragm that abuts against the circuit board. The at least one inductor member is electrically coupled to the circuit board, is connected to the at least one diaphragm, and is adjacent to the at least one magnetic member. When the input panel is pushed toward the circuit board, the circuit board and the at least one inductor member are conducted, and the circuit board alternately distributes electric currents ire different directions to the at least one inductor member such that the at least one magnetic member alternately, attracts and pushes the at least one inductor member, thereby urging the at least one diaphragm to vibrate upon movement of the at east one inductor member.
