Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

When updating a micom code in a display apparatus, errors can occur, leading to the apparatus stopping operation, and users face difficulties in restoring it without additional equipment, as the CPU and micom fail to function normally.

Innovation Solution

The display apparatus includes a micom that stores a system code for driving the CPU, allowing it to operate even if an error occurs during code updates, enabling automatic restart of the micom code update process using the system code and flag signals transmitted through GPIO pins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the CPU updates the micom code, then the micom code can be upgraded, but if an error occurs during the update process, the display apparatus stops operating and cannot be restored

Engineering Contradiction:

Improvemicom code update capabilityVSAvoidsystem operation stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent stores a system code in the micom's memory that can drive the CPU independently of the micom code. This preliminary preparation ensures that if an error occurs during micom code update, the system can still operate using the pre-stored system code, enabling automatic restoration without external equipment.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the micom code is updated, then new functions can be implemented, but the system becomes vulnerable to errors that halt operation

Engineering Contradiction:

Improvefunctional capabilityVSAvoidsystem restore ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent enables the system to restore itself automatically by using the pre-stored system code to drive the CPU when micom code update fails. The CPU can detect the update error and restart the update process using the system code, eliminating the need for external jig equipment and simplifying user operation.

Inventive Principle:

Principle #25Self-service

3Productivity

If the system stops operating due to micom code update error, then no further processing can occur, but restoring the system requires separate jig equipment

Engineering Contradiction:

Improveupdate process efficiencyVSAvoidrestoration equipment requirement

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a system code as an intermediary that can drive the CPU independently of the micom code. This intermediary enables the system to continue operating or restore itself without requiring external jig equipment, thereby reducing device complexity while maintaining update efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)
