Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current serial data transfer methods are inadequate for high-speed and complex driving control of recording heads, requiring increased information and transfer speed while also reducing device size and cost.
Innovation Solution
A driving device configuration that includes a driving unit for pulse signals, input units for synchronized data signals with flags, and setting units to manage first and second information, allowing for efficient transfer of data by batching second information and using flags to control data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the amount of information for controlling the recording head is increased to support high-speed and complex driving control, then the control capability is improved, but the transfer speed requirement increases and device size/cost increase
Solution Approach 1:
The data signal is segmented into multiple types of information (first information for drive coil control, second information for plate control) that are transferred separately through the same serial interface. This segmentation allows efficient use of the transfer bandwidth by sending different types of control data in an organized manner, supporting complex driving control without proportionally increasing transfer speed requirements
Solution Approach 2:
The second information is retained in advance in a retaining unit before being transferred to the driving unit. This preliminary action allows the system to prepare control data ahead of time and transfer it efficiently through the serial interface, reducing the burden on transfer speed while maintaining complex control capability
2Adaptability or versatility
If the amount of information for controlling the recording head is increased to support high-speed and complex driving control, then the control capability is improved, but the device size and cost increase
Solution Approach 1:
The same serial data transfer interface is used to transfer multiple types of information (drive coil control data, plate control data, and their corresponding flags). This multi-functional use of a single interface reduces the need for separate dedicated interfaces for each control function, thereby reducing device size and complexity while maintaining comprehensive control capability
Solution Approach 2:
Control information is segmented into different types (first information, second information) with corresponding flags, allowing the system to manage complex control requirements through organized data structures rather than requiring separate physical interfaces for each control type
3Productivity
If flags are used to control data processing and batch second information, then the transfer efficiency is improved, but the data processing complexity increases
Solution Approach 1:
Flags are used as control parameters to change the processing state of the data signal. By setting or clearing specific flag bits, the system can control whether second information should be retained or transferred, providing an efficient mechanism for batch processing without requiring complex control logic

AI summary
Data transfer is realized to support a high-speed and complex driving control of the driving element. A driving device includes a driving unit configured to supply a driving element with a pulse signal that determines a driving period to drive the driving element, an input unit configured to receive, in synchronization with a trigger signal, a data signal containing first information, second information, a first flag and a second flag that determine a waveform of the pulse signal, a first setting unit configured to set in the driving unit the first information that is input to the input unit, a retaining unit configured to read and retain the second information on the basis of the first flag, and a second setting unit configured to set in the driving unit the second information that is retained in the retaining unit on the basis of the second flag.
