Vehicle USB Bluetooth Transmitter for Forgotten Item Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of systems in the market that alert users if they have forgotten essential items in their vehicle before leaving.
Innovation Solution
A transmitter system that includes a USB plug, CPU, and a speaker, which pairs via Bluetooth with forgotten items and emits an alert sound when the vehicle is powered on and the item is out of Bluetooth range, allowing identification and retrieval of items like wallets, purses, and laptops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a system is implemented to alert users of forgotten items, then user awareness of forgotten items is improved, but device complexity increases
Solution Approach 1:
The patent introduces a transmitter as an intermediary device that mediates between the forgotten item and the user. The transmitter detects the absence of the item and communicates this information to the user through audio alerts, thereby resolving the contradiction by adding a simple intermediary component rather than complex system integration
Solution Approach 2:
The transmitter is designed to work with multiple types of forgotten items (wallets, purses, laptops, etc.) through universal Bluetooth connectivity. This multi-functionality approach allows a single device to alert users about various items without requiring separate specialized systems for each item type, thus improving reliability while controlling complexity
2Measurement precision
If Bluetooth pairing capability is added to identify forgotten items, then item detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical or manual item tracking systems with Bluetooth wireless communication technology. The transmitter uses Bluetooth to automatically detect and identify forgotten items without requiring physical tags, mechanical switches, or manual registration, thereby achieving high detection accuracy while minimizing device complexity through wireless substitution
3Loss of information
If audio alert function is implemented to notify users, then information delivery is improved, but energy consumption increases
Solution Approach 1:
The transmitter implements periodic action by only activating the audio alert function when specifically triggered - that is, when the system detects that a forgotten item has been left in the vehicle. The speaker remains inactive during normal operation and only consumes energy when needed to deliver the alert message, thereby minimizing overall energy consumption while ensuring effective information delivery when required
Solution Approach 2:
The system uses self-service by leveraging the vehicle's existing power infrastructure through USB ports. The transmitter draws power from the vehicle's electrical system rather than requiring an independent power source, and the audio alert serves the dual purpose of informing the user while the system automatically manages its own operational state based on detection triggers
Data Source
AI summary
A transmitter to alert a user of a forgotten item, the transmitter including a transmitter universal serial bus (USB) plug insertable into a USB port within a vehicle to provide power to the transmitter when the vehicle is powered on, a transmitter central processing unit (CPU) electrically connected to the transmitter USB plug to allow the transmitter to BLUETOOTH pair with the forgotten item, and a transmitter speaker electrically connected to the transmitter CPU to emit a sound to alert the user when the forgotten item is out of BLUETOOTH connectivity range with respect to the transmitter, such that the transmitter speaker emits the sound in response to the vehicle being powered on and in response to the forgotten item being out of BLUETOOTH connectivity range with respect to the transmitter.
