Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication protocols between computing devices and peripheral input devices, such as styluses, face inefficiencies in data transfer due to limited bandwidth and time allocation for uplink blocks, leading to delays or prevention of data uploads, especially when using electrostatic or electromagnetic communication.
Innovation Solution
Transitioning from a multiuse communication protocol to a dedicated uplink protocol that prioritizes consecutive data uploads from the computing device to the peripheral input device, eliminating input-related communication during this phase to ensure efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multiuse communication protocol is used to exchange data between computing device and peripheral input device, then bidirectional communication (both uplink and downlink) can be maintained, but data upload speed and efficiency are limited due to shared bandwidth and time allocation
Solution Approach 1:
The system dynamically transitions between two communication protocols based on operational needs: using a multiuse protocol during active input phases for bidirectional communication, and switching to a dedicated uplink protocol during upload phases to maximize data transfer speed. This dynamic adaptation resolves the contradiction by allowing the system to optimize for speed when uploading while maintaining flexibility when interactive communication is needed.
Solution Approach 2:
The communication process is segmented into distinct phases: input reception phase using multiuse protocol and data upload phase using dedicated uplink protocol. By dividing the communication workflow into separate segments with specialized protocols for each, the system achieves high upload speeds during upload segments while preserving communication flexibility during input segments.
2Quantity of substance
If bandwidth is allocated for bidirectional communication in multiuse protocol, then both uplink and downlink can function simultaneously, but uplink bandwidth is limited leading to delayed or prevented data uploads
Solution Approach 1:
The system performs preliminary actions by completing all input reception and processing before initiating the dedicated uplink phase. This ensures that the data is ready for upload in advance, allowing the subsequent upload phase to proceed without delays caused by simultaneous bidirectional communication interruptions.
Solution Approach 2:
The dedicated uplink protocol enables continuous data transmission from the computing device to the peripheral input device without interruption from downlink communications. This continuous useful action maximizes the quantity of data transferred while minimizing upload delay, as the upload process proceeds uninterrupted until completion.
3Device complexity
If electrostatic or electromagnetic communication is used for wireless connection, then no dedicated hardware is needed, but communication bandwidth is limited affecting upload performance
Solution Approach 1:
The system changes communication parameters by switching protocols based on operational mode: using multiuse protocol with shared bandwidth during input mode, and transitioning to dedicated uplink protocol with prioritized bandwidth allocation during upload mode. This parameter change allows electrostatic or electromagnetic communication to achieve high upload efficiency without requiring dedicated hardware, as the protocol optimization compensates for the inherent bandwidth limitations of the wireless medium.

AI summary
The disclosed technology provides wireless uplink transmission from a computing device to a peripheral device by communicating over a wireless connection between a digitizer of the computing device and the peripheral device by a multiuse communication protocol in which the digitizer receives input from the peripheral input device to affect operation of the computing device, transitioning communication from the multiuse communication protocol to a dedicated uplink communication protocol in which communication between with the peripheral input device includes transmission of multiple consecutive uplink blocks before the digitizer accepts downlink communications from the peripheral input device, and transmitting, while using the dedicated uplink communication protocol, consecutive data uplink blocks representing an upload to the peripheral input device before the digitizer accepts downlink communications from the peripheral input device.
