Wireless Door Lock Actuation via Haptic Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deadbolt locks require manual operation and are susceptible to unauthorized access, especially in situations where electronic controllers are unavailable or compromised, and there is a need for a wireless access control system to securely lock or unlock doors.
Innovation Solution
A wireless access control system that utilizes haptic feedback or motion input from a user remote access device to interact with an intelligent door lock system, allowing controlled access to dwellings and vehicles, featuring a drive shaft, circuit, and energy source, enabling remote locking and unlocking through a mobile device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation of deadbolt locks is used, then the locking mechanism is simple and reliable, but the ease of operation deteriorates due to requiring physical presence and manual intervention
Solution Approach 1:
The patent replaces manual mechanical operation with wireless electronic control. A mobile device sends wireless signals to an actuator that automatically operates the deadbolt, eliminating the need for physical manual intervention while maintaining the mechanical reliability of the locking mechanism.
Solution Approach 2:
The patent introduces wireless communication and electronic actuators as intermediaries between the user and the locking mechanism. The mobile device communicates wirelessly with the actuator, which then mechanically actuates the deadbolt, providing remote operation capability while preserving the simplicity and reliability of the mechanical lock itself.
2Ease of operation
If electronic controllers are used for door locks, then the ease of operation improves through remote access, but the reliability deteriorates when electronic systems become unavailable or compromised
Solution Approach 1:
The patent segments the locking system into independent electronic control and mechanical locking components. The electronic actuator provides remote operation capability, while the mechanical deadbolt and latch remain as standalone reliable components that can function independently if electronic systems fail.
Solution Approach 2:
The patent incorporates manual operation capability as a backup mechanism that can be used if electronic systems fail. The mechanical components are designed to be operable by hand or key even when electronic power and control are unavailable, providing redundancy and ensuring continuous reliability.
3Ease of operation
If wireless access control systems are implemented, then the ease of operation improves through remote locking and unlocking, but the device complexity increases due to additional electronic components
Solution Approach 1:
The patent extracts the electronic control functionality into a separate wireless communication module and actuator system, distinct from the core mechanical locking mechanism. This allows the complex electronic components to be added or removed independently while preserving the simplicity of the fundamental lock operation.

AI summary
A wireless access control system is provided to lock or unlock a first door at a dwelling of a user. A user remote access device accepts input based on haptic feedback or motion. The user remote access device includes a vibration mode provides an alert to the user of the remote access device. The user remote access device is configured to be in communication with an intelligent door lock system at the dwelling with the first door. The intelligent door lock system includes: a drive shaft, a circuit coupled to an engine configured to cause a rotation of the drive shaft, and an energy source coupled to the drive shaft. In response to the user remote access device accepting input based on haptic feedback or motion the bolt is caused to move and the first lock is locked or unlocked.
