Solution Overview

Problem

Updating firmware in electronic musical instruments requires complex user operations, such as obtaining and specifying compatible firmware, which is cumbersome.

Innovation Solution

An electronic device with a confirmation, transmission, and instruction unit that automatically confirms firmware compatibility, transmits compatible firmware, and instructs the electronic musical instrument to update, reducing user effort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If firmware update is performed using a PC application, then firmware can be updated, but user operations become complicated

Engineering Contradiction:

Improvefirmware update capabilityVSAvoiduser operations

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The electronic device automatically performs firmware compatibility confirmation, firmware transmission, and update execution without requiring user operations. The device self-services the entire firmware update process by autonomously checking compatibility with the host device, transmitting appropriate firmware, and executing the update, thereby eliminating the need for complicated user operations while maintaining reliable firmware updates

Inventive Principle:

Principle #25Self-service

2Reliability

If firmware compatibility is manually specified, then correct firmware can be selected, but user effort increases

Engineering Contradiction:

Improvefirmware compatibilityVSAvoiduser effort

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The electronic device performs preliminary firmware compatibility confirmation before transmitting firmware. The device automatically checks whether the firmware is compatible with the host device, retrieves appropriate firmware based on compatibility results, and prepares it for transmission. This preliminary automated compatibility check eliminates the need for users to manually specify firmware while ensuring correct firmware selection, thereby reducing user effort and time

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If automated firmware update is implemented, then user effort is reduced, but compatibility verification becomes critical

Engineering Contradiction:

Improveuser effortVSAvoidcompatibility verification process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The electronic device performs firmware compatibility confirmation as a preliminary step before transmitting firmware. This automated compatibility verification process checks whether the firmware is suitable for the host device, retrieves appropriate firmware based on compatibility results, and only then proceeds with transmission and update execution. This preliminary verification approach simplifies user operations while managing the complexity of compatibility checks through automated system processes

Inventive Principle:

Principle #10Preliminary action

AI summary

When an electronic musical instrument is attached to an external input/output device 13 of the sound source device 1, model information and a firmware version are received from the target electronic musical instrument, and the received version is compared with an incompatible version in a firmware table 11b. When the acquired version is an incompatible version or below, update data of the target electronic musical instrument in the firmware table 11b is acquired and transmitted to the target electronic musical instrument together with an instruction to update using the update data.
