Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices for MIDI data transmission and reception between electronic musical instruments and other devices face communication errors due to timing coincidences when multiple devices are connected, leading to delayed data transmission and reception.
Innovation Solution
A wireless communication device that sets and transmits different communication intervals to each paired device, preventing timing coincidences and ensuring reliable MIDI data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the slave performs wireless communication with multiple masters using time division and staggering timings, then the slave can communicate with multiple masters, but communication errors occur when timing coincidences happen due to individual clock differences
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the communication interval for each master-slave pair based on their individual clock characteristics. Instead of using a fixed communication interval for all pairs, the system measures the actual clock intervals of each master and slave, calculates compensation values, and sets different communication intervals for different pairs to prevent timing coincidences and communication errors.
2Device complexity
If a fixed communication interval is used for all master-slave pairs, then the communication protocol is simple, but timing coincidences occur due to individual clock differences causing communication errors
Solution Approach 1:
The patent applies preliminary action by performing clock interval measurement and communication interval setting before actual MIDI data transmission begins. The system pre-calculates the appropriate communication intervals for each pair based on their clock characteristics, storing these settings for use during communication. This preliminary configuration prevents timing coincidences from occurring during actual data transmission.
3Reliability
If communication timing is staggered for multiple pairs, then timing coincidences are avoided, but the communication interval must be individually set for each pair increasing system complexity
Solution Approach 1:
The patent applies self-service by enabling each master and slave device to autonomously measure its own clock interval and participate in the calculation of its specific communication interval. The devices automatically exchange timing information and adjust their communication parameters without requiring manual configuration or complex external control, simplifying the overall system management while maintaining reliable staggered timing.
