Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking and unlocking technologies require manual input of codes or remote control, posing difficulties for users with full hands or disabilities.
Innovation Solution
A door locking and unlocking system using a pressure-sensitive pad that recognizes a sequence of footsteps to control a deadbolt, allowing hands-free operation and accommodating various user abilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual code input is used for door locking, then security control is achieved, but usability deteriorates for users with full hands or disabilities
Solution Approach 1:
The patent replaces the manual mechanical code input system with a pressure-sensitive pad that detects footstep patterns. This substitution allows users to operate the door locking system using foot movements instead of hand movements, thereby improving ease of operation and accessibility for users with full hands or disabilities while maintaining security control through recognized step sequences
2Ease of operation
If remote control devices are used for door locking, then convenience is improved, but accessibility deteriorates for users with limited mobility
Solution Approach 1:
The patent implements a self-service mechanism where the door locking system automatically detects and recognizes predetermined step sequences on the pressure-sensitive pad. This eliminates the need for users to manually operate remote control devices, as the system autonomously responds to recognized footstep patterns, thereby improving accessibility for users with limited mobility while maintaining convenient door control

AI summary
Embodiments are directed to a step pad door lock system that processes the rhythm, pressure, and/or sequence of a user's steps on a pad. The step pad door lock system locks and unlocks doors based on the rhythm, pressure, and/or sequence of steps. If the rhythm, pressure, and/or sequence is the same as a user-defined predetermined rhythm, pressure, and/or sequence (acting as the password), the door unlocks.
