USB Dongle Retrofit for Remote Building Equipment Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building equipment systems, such as elevators, HVAC, and security systems, often lack remote communication, self-monitoring, and data archiving capabilities, making it difficult to upgrade or enhance their functionalities effectively.
Innovation Solution
A dongle system that facilitates wireless connectivity between building equipment and mobile devices, enabling remote communication and data exchange through Bluetooth, Wi-Fi, or GSM, allowing for the download of service commands and data upload, and integration with cloud servers to enhance system capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If building equipment systems are upgraded with remote communication and monitoring capabilities, then system functionality and operational efficiency are improved, but device complexity and upgrade cost increase
Solution Approach 1:
A dongle serves as an intermediary device that connects building equipment to wireless networks, enabling remote communication without modifying the equipment's core system. The dongle handles all wireless protocol communications, acting as a mediator between the legacy equipment and modern network infrastructure, thus adding functionality while minimizing complexity changes to the original system
Solution Approach 2:
The communication functionality is segmented into a separate, standalone dongle device rather than being integrated into the building equipment itself. This allows the communication capabilities to be added independently, enabling upgrades without complicating the main equipment system architecture
2Productivity
If building equipment systems are upgraded with remote control and monitoring capabilities, then operational efficiency is improved, but upgrade cost increases
Solution Approach 1:
The dongle is designed as a cost-effective, relatively simple device that can be easily manufactured and deployed. Rather than investing in expensive, complex integrated systems, the solution uses affordable wireless communication modules that provide the necessary functionality at minimal cost, making upgrades economically viable
Solution Approach 2:
The dongle is designed to be universally compatible with multiple types of building equipment and supports multiple wireless communication protocols (WiFi, Bluetooth, cellular). This multi-functionality allows a single device design to serve various applications, reducing per-unit costs through economies of scale and eliminating the need for expensive custom solutions for each equipment type
