Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional solutions for tracking user activities on construction sites and other mobile worker applications are costly and inefficient, relying on expensive smartphone equipment and proprietary networks, and struggle with data collection and communication limitations, especially in environments with BLE interference or signal range issues.
Innovation Solution
A computer-implemented method using Bluetooth Low Energy (BLE) beacon devices, such as smart keyfobs, to advertise user activity data to nearby smartphones or tablets, enabling accurate tracking and communication of worker presence, tasks, and emergency requests through a custom advertisement payload, leveraging the iBeacon specification and caching mechanisms to overcome range limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional smartphone-based tracking solutions are used, then accurate worker activity tracking is achieved, but device cost and system complexity increase significantly
Solution Approach 1:
The patent replaces expensive smartphones with inexpensive BLE beacon devices that can be easily deployed and replaced. These beacons are simple, low-cost devices that broadcast activity data without requiring complex processing or display capabilities, effectively serving as disposable or temporary tracking nodes throughout the workspace.
Solution Approach 2:
The patent extracts the core tracking function from the smartphone platform and isolates it into dedicated BLE beacon devices. By separating the activity data collection function from the expensive smartphone hardware, the system achieves accurate tracking while eliminating the need for workers to carry or use smartphones for this specific purpose.
2Reliability
If proprietary network infrastructure is deployed, then reliable data collection is achieved, but implementation cost and maintenance overhead increase
Solution Approach 1:
The patent leverages the universality of BLE technology, which is already widely integrated into smartphones, tablets, and computers. By using this existing, universal communication protocol instead of deploying a proprietary network, the system achieves reliable data collection through devices workers already carry, eliminating the need for expensive specialized infrastructure.
Solution Approach 2:
The system utilizes the smartphone's existing BLE capabilities to perform scanning and data collection without requiring additional dedicated infrastructure. The worker's own smartphone serves the dual purpose of both the activity source (via nearby beacons) and the data collector, eliminating maintenance overhead for separate collection devices.
3Productivity
If BLE beacon advertising is used, then cost-effective tracking is achieved, but data transmission range and reliability are limited
Solution Approach 1:
The patent employs multiple BLE beacons broadcasting simultaneously in the workspace. While each individual beacon has limited range, the collective coverage of multiple beacons ensures that at least one beacon's signal is always detectable by the smartphone, providing redundant data transmission paths that overcome the limited range of any single beacon.

Data Source
AI summary
A system for tracking worker activity on a job site over a local area network. The system comprises providing a mobile device for each worker. Each mobile device has a programmable micro-processor, memory and radio modem with antenna, that is configured to emit radio signals in the form of an advertisement packet as a beacon over a simplex local network. Each mobile device has a push button for a worker to press upon completing an activity. The programmable micro-processor is configured to track time to complete an activity and handle worker interaction with the pressing of the push button by calculating the duration between consecutive button pushes and broadcasting this duration along with a device identifier within the advertisement packet over the local network.
