Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital inking devices face challenges in efficiently receiving firmware updates due to limited electrostatic communication bandwidth, which is further constrained by the need to allocate bandwidth for inking signals, leading to delays or incomplete uploads when using multiuse communication protocols.
Innovation Solution
Transitioning from a multiuse communication protocol to a dedicated uplink communication protocol during firmware updates, where the digitizer dedicates bandwidth solely for uploading data to the digital inking device, ensuring completion of large updates without interrupting inking functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiuse communication protocol is used for both inking signals and firmware updates, then the electrostatic communication channel can serve multiple functions, but the firmware update speed is reduced and may result in incomplete uploads due to bandwidth sharing
Solution Approach 1:
The communication protocol is segmented into dedicated phases: a first protocol phase for inking signals and a second protocol phase for firmware updates. This temporal segmentation allows the same electrostatic communication channel to be exclusively allocated to firmware updates during the update phase, eliminating bandwidth sharing conflicts and ensuring complete, high-speed uploads without interrupting inking functionality in other phases.
2Device complexity
If electrostatic communication bandwidth is shared between inking signals and firmware updates, then hardware complexity is reduced, but update completion reliability is compromised due to bandwidth constraints
Solution Approach 1:
The communication system dynamically switches between different protocol modes based on the operational phase. During firmware update phases, the system transitions to a dedicated uplink communication mode that allocates maximum bandwidth to update data transmission. This dynamic adaptation ensures reliable update completion without requiring additional dedicated hardware, as the same electrostatic channel flexibly reconfigures its bandwidth allocation.
3Productivity
If dedicated uplink communication protocol is used for firmware updates, then update speed and completion reliability are improved, but communication protocol complexity increases
Solution Approach 1:
The communication system employs periodic protocol switching, alternating between inking signal transmission and firmware update phases. During designated update periods, a dedicated uplink protocol is activated to maximize transfer speed and reliability. This periodic structure manages protocol complexity by confining the sophisticated dedicated protocol to specific time windows, while using simpler protocols for routine inking operations, thus balancing performance gains with implementation complexity.

AI summary
The disclosed technology controls a digital inking device by communicating electrostatic inking signals between the digital inking device and an ink-receiving computing device in an inking mode enabling the digital inking device to render digital ink in a display of the ink-receiving computing device via the electrostatic inking signals, detecting proximity of a peripheral communication device relative to the digital inking device, transitioning the digital inking device from the inking mode to a non-inking mode that terminates communication of the electrostatic inking signals between the digital inking device and the ink-receiving computing device, based at least in part on the detecting operation, and communicating electrostatic data signals in the non-inking mode between the digital inking device and the peripheral communication device in the non-inking mode, based at least in part on the transitioning to the non-inking mode.
