Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart doorbells with remote monitoring functions are vulnerable to theft as malicious individuals can disassemble them to disable the network and remote monitoring capabilities, allowing unauthorized access without detection.
Innovation Solution
A smart doorbell design incorporating a case set with a locking mechanism, vibration sensing module, and alarm module that generates a vibration when tampered with, alerting authorities through a connected network module, distinguishing intentional disassembly from random movements like wind or rain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the smart doorbell provides remote monitoring function, then the user can check the situation in front of the home anytime, but thieves can disassemble the case to damage electronic components and disable the monitoring function
Solution Approach 1:
The patent applies preliminary anti-action by equipping the smart doorbell with a vibration sensing module and alarm module before any theft occurs. When the locking unit is manipulated or the case is disassembled, the vibration sensing module detects the abnormal vibration and triggers the alarm module to send alerts to the user's smartphone, preventing the theft from succeeding without detection.
Solution Approach 2:
The patent implements preliminary action by providing a locking unit that automatically locks the case set to prevent disassembly. The locking unit includes a locking protrusion and locking groove structure that engages to secure the first case and second case, preventing thieves from accessing and damaging the electronic components inside.
2Reliability
If the locking unit is designed to secure the case set, then the anti-theft function is improved, but the device complexity increases due to additional locking mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the locking function into separate modular components: a locking unit with locking protrusion and locking groove, a vibration sensing module, and an alarm module. This modular design allows each component to perform its specific function independently while maintaining overall system simplicity and ease of assembly.
Solution Approach 2:
The patent uses an intermediary approach by introducing a vibration sensing module as a mediator between the locking unit and the alarm module. The vibration sensing module detects vibrations from locking unit manipulation and transmits this information to trigger the alarm, creating a simple yet effective connection without requiring complex direct integration.
3Reliability
If the vibration sensing module detects abnormal vibrations to trigger alarm, then the anti-theft function is improved, but false alarms from environmental causes like wind or rain may occur
Solution Approach 1:
The patent applies dynamics by making the alarm module's operation adjustable based on detected vibration characteristics. The system can adapt its sensitivity and response thresholds dynamically, allowing it to distinguish between the specific vibration patterns of theft attempts and the different patterns caused by environmental factors like wind or rain, thereby reducing false alarms.
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
The smart doorbell effectively alerts security services when attempted disassembly occurs, enhancing home security by preventing unauthorized access and minimizing false alarms from environmental causes.
Implementation Method 1
When the locking unit rotates, the locking unit causes the vibration unit to rotate such that the vibration transferring unit moves back and forth on the plurality of crests and the plurality of troughs to generate a vibration
Implementation Method 2
an elastic force of the elastic unit moves the moving unit, allowing the moving unit to move back and forth on the crests and the troughs to generate the vibration
