Print Device Functionality Control via Refill Supply Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing print devices face challenges in altering functionalities across different models and locations without disrupting operations, especially when devices are behind firewalls or inaccessible, leading to resource-intensive updates and potential device replacement.
Innovation Solution
Enabling or disabling print device functionalities through signals received from a universal refill supply container, allowing for remote selection and activation of desired functionalities without direct remote device communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If firmware or software updates are used to alter functionalities on print devices, then functionalities can be modified, but device downtime and resource usage increase
Solution Approach 1:
The patent applies preliminary action by enabling functionalities to be altered in advance through the refill supply container before the device needs to operate with new functionalities. The container is prepared with instructions or configuration data that automatically enable or disable specific print functionalities when installed, eliminating the need for time-consuming firmware updates or technician intervention during device operation.
2Adaptability or versatility
If technicians are deployed to alter functionality at the device location, then functionalities can be customized, but resource consumption and operational disruption increase
Solution Approach 1:
The patent implements self-service by designing the refill supply container to automatically configure device functionalities without requiring technician intervention. The container includes instructions or software that automatically execute when the container is installed on the device, enabling the device to self-configure its functionalities based on the container's contents or associated configuration data.
3Adaptability or versatility
If print devices are sent to another location for updates, then functionalities can be modified, but operational continuity is disrupted
Solution Approach 1:
The patent applies the extraction principle by separating the functionality modification process from the device itself and embedding it in the refill supply container. The configuration instructions or software are extracted from the device and placed in the container, allowing functionalities to be altered simply by replacing the container rather than transporting or disrupting the main device operation.
4Ease of operation
If remote connection is established with print devices behind firewalls, then functionalities can be altered remotely, but connection reliability decreases
Solution Approach 1:
The patent uses the refill supply container as an intermediary medium to transfer functionality configuration data to the device. Instead of attempting unreliable remote connections through firewalls, the configuration instructions are physically carried by the container and automatically transferred when the container is installed, providing a reliable alternative to network-based remote configuration.
