Smart Door Lock Wake-Up Control for Low Idle Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart door locks face high power consumption due to the need for continuous power to maintain control functionality, which is not efficiently managed in existing technologies.
Innovation Solution
A door lock system that includes a sensing module to determine the presence of a human body within a preset detection range, powering on only the main controlling and unlocking modules when a person is present, and powering off when no one is present, utilizing a timing module to manage power states and reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controlling module is kept in power-on state to ensure timely control of the door lock, then the responsiveness and control functionality are improved, but the power consumption increases significantly
Solution Approach 1:
The controlling module alternates between power-on and power-off states based on periodic detection of human presence. The sensing module continuously monitors for human bodies, and only when detected does it power on the controlling module for a limited duration to process unlocking operations, then powers it off again. This periodic activation resolves the contradiction by providing responsiveness only when needed rather than maintaining continuous power.
Solution Approach 2:
The sensing module automatically detects human presence and triggers the power-on state of the controlling module without external intervention. When no human is detected, the system self-transitions to power-off state. This automated self-service mechanism eliminates the need for manual power management while optimizing between responsiveness and power consumption.
2Ease of operation
If the sensing module continuously monitors for human presence to enable timely unlocking, then the convenience is improved, but the power consumption increases
Solution Approach 1:
The sensing module employs periodic detection rather than continuous monitoring. It activates the controlling module only during detected human presence events, maintaining convenience by being ready to unlock when needed while consuming minimal power during idle periods when no human is present.
3Use of energy by moving object
If the door lock operates in low-power sleep mode to reduce energy consumption, then the power efficiency is improved, but the response time to unlock increases
Solution Approach 1:
The sensing module performs preliminary detection of human presence before the user attempts to unlock. When a human is detected, the system pre-activates the controlling module, so that when the unlocking operation is initiated, the module is already powered on and ready to process the request immediately, eliminating any delay that would occur from waking from sleep mode.

AI summary
The present disclosure discloses a door lock, a door lock controlling method and a door lock controlling device. The door lock includes a main controlling module, an unlocking module and a sensing module. The sensing module is configured to determine whether a human body is present within a first preset detection range; if yes, the main controlling module and the unlocking module are controlled to be powered on; and if no, the main controlling module and the unlocking module are controlled to be powered off. In the present disclosure, only the sensing module is in an operating state and other modules are not powered on when there is no user who is trying to open the door. Therefore, the power consumption of the door lock is reduced.
