Doorbell Voltage Threshold Switching for Remote Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional doorbell systems are limited in notifying remotely located individuals of a visitor's arrival, as the notification sound is typically only audible within a short distance from the chime, making it difficult for homeowners to be aware of a visitor ringing the doorbell when they are not nearby.
Innovation Solution
A doorbell system comprising an electronic doorbell with a camera and button, an electronic switch assembly, and a digital chime with a speaker, where the electronic switch assembly blocks or allows electricity to pass through the chime based on a threshold voltage, ensuring the chime emits a notification sound only when the voltage exceeds a predetermined level, allowing remote notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If digital chimes are used to play a wider variety of sounds, then the notification sound quality is improved, but the electricity consumption increases
Solution Approach 1:
The system dynamically switches between digital and analog chime modes based on the state of the smart device. When the smart device is available, digital chime with higher quality sounds is used; when the smart device is unavailable or during certain operational states, analog chime with lower power consumption is used. This dynamic adaptation resolves the contradiction between sound quality and energy consumption.
Solution Approach 2:
The system changes the operational parameters of the chime system by switching between two distinct modes: digital mode (higher power, better sound quality) and analog mode (lower power, acceptable sound quality). The switch assembly controls this parameter change by routing electricity differently based on system state, allowing optimization of the balance between sound quality and energy consumption.
2Use of energy by moving object
If analog chimes are used for short duration electricity consumption, then the electricity usage is reduced, but the notification sound can only be heard within a short distance
Solution Approach 1:
The system provides universal notification capability through multiple pathways: local acoustic notification (analog chime for short-range, digital chime for extended-range), and remote electronic notification (smart device alerts for distant notification). This multi-functional approach ensures that the system can achieve both low power consumption and wide notification coverage by selecting the appropriate notification pathway based on the situation.
Solution Approach 2:
The smart device acts as an intermediary that extends the notification coverage area. Instead of relying solely on acoustic propagation limits, the system uses the smart device's display and notification capabilities to convey doorbell alerts to occupants anywhere in the building, effectively overcoming the physical limitation of sound distance while maintaining energy efficiency.
3Measurement precision
If the electronic switch assembly blocks electricity below threshold voltage, then the chime activation precision is improved, but the device complexity increases
Solution Approach 1:
The system uses parameter change (voltage threshold) as a simple control mechanism to achieve precise chime activation. The switch assembly is designed with a predetermined voltage threshold that automatically determines whether to activate the chime, converting a potentially complex decision-making process into a simple electrical parameter comparison. This maintains precision while minimizing added complexity.
Solution Approach 2:
The switch assembly performs self-service by automatically making the activation decision based on the voltage threshold criterion. No additional control logic, processors, or decision-making systems are needed - the electrical parameters themselves drive the activation decision. This self-service approach achieves precise control without proportionally increasing device complexity.
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
Enables remote notification of a visitor's arrival by ensuring the doorbell chime emits a sound only when the voltage exceeds a certain threshold, effectively alerting individuals regardless of their location within the building.
Implementation Method 1
The electronic switch assembly may define a first state and a second state. The first state may occur in response to a first electricity that is less than a first threshold, and the second state may occur in response to a second electricity that is greater than the first threshold.
Implementation Method 2
an electronic chime electrically coupled to the electronic switch assembly, wherein the electronic chime comprises a speaker configurable to emit a notification sound in response to the visitor pressing the button of the electronic doorbell

AI summary
A doorbell system can be used to block a first electricity that is less than a first threshold from entering an electronic chime. By blocking the first electricity from entering the electronic chime, the electronic chime is not allowed to emit a notification sound. The doorbell system can also be used to allow a second electricity that is greater than the first threshold to enter the electronic chime. By allowing the second electricity to enter the electronic chime, this can allow the electronic chime to emit a notification sound in response to a visitor being present.
