Projected Keypad Interface for Aesthetic and Secure Home Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security and automation systems require direct user interaction to access information and control home automation devices, which can detract from aesthetics and compromise security, as they often rely on visible keypads that may attract attention and require manual activation.
Innovation Solution
Implementing a system with proximity detection using motion sensing technology to project home automation system data and interactive keypads onto surfaces, allowing users to access information and control systems without direct interaction, and integrating keyless door locking mechanisms with biometric or device authentication to ensure secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical keypad is installed on the home automation device, then user interaction capability is improved, but aesthetic appeal deteriorates
Solution Approach 1:
The patent uses projection technology to create a virtual copy of the keypad on the wall surface instead of installing a physical keypad. The projected keypad provides all necessary input functionality while maintaining the aesthetic appearance of a minimal or non-intrusive device housing.
Solution Approach 2:
The patent transitions the keypad from a two-dimensional physical surface mounted on the device to a projection on the three-dimensional wall surface. This allows the keypad to be displayed in the spatial dimension where it is most needed (on the wall in front of the user) while keeping the device itself aesthetically pleasing.
2Ease of operation
If a visible keypad is installed on the door lock, then user access functionality is improved, but security deteriorates
Solution Approach 1:
The patent projects the keypad virtually onto the wall near the door lock rather than installing a visible physical keypad on the lock itself. This maintains access functionality while reducing the visual target that could attract burglars' attention to the security system's location and capabilities.
Solution Approach 2:
The patent uses light projection as an intermediary medium to deliver the keypad interface without requiring physical components on the door lock. The projection serves as a mediator that provides functionality while maintaining the aesthetic and security benefits of a minimal physical presence.
3Use of energy by moving object
If the device requires manual activation, then power consumption is reduced, but user convenience deteriorates
Solution Approach 1:
The patent incorporates motion sensing technology that automatically detects when a user approaches and activates the projection without requiring the user to manually turn the device on. The system serves itself by using environmental cues (user presence) to trigger operation, eliminating the need for manual activation while maintaining energy efficiency through automatic deactivation when no motion is detected.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user convenience by providing accessible home automation information and control without manual interaction, while maintaining aesthetic appeal and increasing security by minimizing visible system components and requiring authorized access.
Implementation Method 1
a proximity detector integrated into, or in communication with, the home automation device or door lock to allow for activation of the projection based on detected user approach or proximity, for example by using motion sensing technology
Implementation Method 2
Existing laser projection technologies often require the user to push a button to turn the system on and off
Data Source
AI summary
A method for security and/or automation systems is described. In one embodiment, the method may include detecting a proximity of a user at a home automation device. The method may further include projecting an external display of home automation system information from the home automation device onto a surface. In some embodiments, the external display may be projected based, at least in part, on the detected proximity of the user at the home automation device.
