Antenna-Integrated Protective Bag for RF Firmware Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Companies face challenges in updating firmware for electronic devices after production, as existing methods require unpacking and powering devices, which is costly and time-consuming, especially with short development cycles and complex embedded firmware.
Innovation Solution
A system utilizing wireless communication and a self-contained power supply allows for firmware updates and operations on unpowered devices through RF signals, with antennas or inductive coupling, enabling communication and power without unpacking or traditional power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If firmware updates are performed by unpacking and powering devices, then firmware can be updated, but the process becomes costly and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-attaching the antenna to the protective bag before the device is sealed. This allows RF communication capability to be established in advance, enabling firmware updates to be performed without unpacking the device. The antenna is positioned and connected during manufacturing, so that when the device needs updating, it can receive RF signals through the protective bag material without requiring physical access or power-up procedures.
Solution Approach 2:
The patent uses the protective bag itself as an intermediary medium. Instead of requiring direct contact between the antenna and device circuitry, the bag material acts as a mediator that allows RF signals to penetrate and communicate with the device. This intermediary approach eliminates the need to break the sealed packaging while maintaining communication capability for firmware updates.
2Reliability
If firmware updates require unpacking devices, then updates can be applied, but production costs increase
Solution Approach 1:
The patent merges the antenna with the protective bag, creating a single integrated component. The antenna is attached to the bag rather than being a separate element that requires manual installation. This merging reduces manufacturing steps and costs, as the antenna-bag assembly can be prepared in advance and attached during the sealing process, eliminating the need for separate antenna installation and device unpacking procedures during updates.
Solution Approach 2:
The system enables self-service firmware updates by allowing the device to receive update signals through the sealed protective bag without human intervention for unpacking. The pre-attached antenna automatically establishes RF communication when update signals are transmitted, enabling the device to update its firmware autonomously while remaining in its protective packaging, thus eliminating labor costs associated with manual unpacking and repackaging.
3Strength
If devices are sealed in protective bags, then protection is provided, but wireless communication becomes difficult
Solution Approach 1:
The patent uses the protective bag material as an intermediary that permits RF signal penetration. The bag maintains its protective function while its material properties allow electromagnetic waves to pass through, enabling the antenna attached to the bag to communicate with the device inside. This intermediary approach preserves both the protective integrity and the wireless communication capability simultaneously.
Solution Approach 2:
The protective bag is given multiple functions: it provides physical protection for the device and simultaneously serves as a mounting surface for the antenna and a transmission medium for RF signals. This multi-functionality allows the bag to maintain device protection while enabling wireless communication capability, resolving the contradiction between protection and adaptability.
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 efficient firmware updates and operations on unpowered devices, reducing costs and schedule misses by allowing communication and power through RF signals or direct electrical connections, even during shipping and storage.
Implementation Method 1
The antenna is configured to receive radio frequency (RF) signals from a source external to the protective bag and transmit RF signals to the source when the antenna is connected to the device and the device is in the protective bag
Implementation Method 2
Another example embodiment includes the use of packaging material for locating the antenna within the box and inductive coupling for communicating with the device
Data Source
AI summary
An apparatus for shipping a device containing a circuit, including a bag sized for holding the device; and an antenna connected to the bag, the antenna having a first end for coupling to the circuit of the device when the device is in the bag so as to allow for radio frequency (RF) communication with the device while the device is in the bag. Separation of the device from the bag causes the antenna to be disconnected from the circuit of the device.
