Digital Pen Processing Unit Reduces Data Transfer Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reading apparatuses, such as digital pens, face inefficiencies in data processing and transfer due to a lack of control over processing and information selection, leading to increased data volume and transfer times, as they must transmit all acquired data without processing it according to specified actions.
Innovation Solution
A reading apparatus with a processing unit that reads codes on a medium, acquires coordinate and processing information, performs specified processing on the data, and transfers only the processed results, allowing for selective data handling and reduced data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all acquired data is transmitted without processing, then data completeness is maintained, but data transfer time and processing load increase
Solution Approach 1:
The patent applies preliminary action by performing data processing before transfer. The reading apparatus executes specified processing operations (such as extraction, transformation, or filtering) on the acquired data from the code before transmitting it to the external device. This preprocessing reduces the data volume and complexity of subsequent processing at the receiving end, thereby decreasing data transfer time while maintaining the necessary information completeness.
2Loss of information
If all acquired data is transmitted without processing, then data availability is ensured, but processing efficiency decreases
Solution Approach 1:
The patent applies the extraction principle by selectively removing unnecessary data components from the acquired information. The processing unit extracts only the relevant data elements specified by the transfer destination requirements, discarding redundant or unwanted information. This extraction process maintains data availability for needed information while significantly improving processing efficiency by reducing the overall data handling burden.
3Productivity
If a processing unit is added to perform specified processing, then data transfer efficiency improves, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the reading apparatus to autonomously perform the specified processing operations without requiring external intervention or complex centralized processing systems. The processing unit within the reading apparatus independently executes processing based on pre-stored processing specifications or received instructions, thereby improving data transfer efficiency while avoiding the need for more complex external processing infrastructure.
Data Source
AI summary
A reading apparatus includes a writing tool body, a reading unit, and a processing unit. The reading unit is included in the writing tool body and reads a code formed on a medium. The processing unit acquires, from the code read by the reading unit, coordinate information regarding coordinates on the medium and processing specifying information which specifies processing to be performed on acquired information. The processing unit also performs predetermined processing specified by the processing specifying information on the acquired information. The acquired information is information acquirable by the reading apparatus and includes the coordinate information. The transfer unit transfers a processing result obtained by the processing unit to a predetermined transfer destination.
