Solution Overview

Problem

Modern set-top boxes require more advanced diagnostic and remote maintenance capabilities due to increasing complexity and ubiquity, as existing diagnostic facilities are limited and often ineffective in identifying issues perceived by users.

Innovation Solution

Incorporating a software component within the set-top box that allows remote access and control, enabling technicians to interface with the device as if they were present, perform diagnostic tests, and retrieve On-Screen Display information, while also measuring power consumption and reporting hardware status changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional limited diagnostic facilities are used in set-top boxes, then device complexity is reduced, but diagnostic capability and fault detection accuracy deteriorate

Engineering Contradiction:
Improvefault detection accuracyVSAvoiddiagnostic facility complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary diagnostic facility that acts as a mediator between the set-top box and external systems. This intermediary component enables comprehensive diagnostics by bridging the gap between limited internal capabilities and the need for advanced fault detection, allowing external devices to interact with and control the set-top box for enhanced diagnostic purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical or hardware-based diagnostic approaches with software-based diagnostic facilities. This substitution enables more sophisticated diagnostics through software components that can be updated and configured remotely, providing advanced fault detection capabilities without proportionally increasing physical device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If comprehensive diagnostic facilities are implemented in set-top boxes, then fault detection capability improves, but device complexity and maintenance costs increase

Engineering Contradiction:
Improveset-top box functionalityVSAvoiddiagnostic facility complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service capabilities where the diagnostic facility can automatically detect faults, perform diagnostics, and even initiate repairs without requiring constant external intervention. The system monitors its own state, identifies issues, and can autonomously execute corrective actions, thereby maintaining high reliability while avoiding the complexity of manual diagnostic systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms where diagnostic results are continuously monitored and used to adjust system operation. The diagnostic facility provides real-time feedback about system health, enabling proactive maintenance and automatic adjustments that prevent failures, thus improving reliability without requiring overly complex preventive measures.

Inventive Principle:
Principle #23Feedback

3Productivity

If remote diagnostic capabilities are added to set-top boxes, then maintenance efficiency improves, but communication requirements and system complexity increase

Engineering Contradiction:
Improvemaintenance efficiencyVSAvoidcommunication interface complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a universal communication interface that serves multiple functions: it enables remote diagnostics, system control, software updates, and configuration management. This multi-functional approach allows a single communication subsystem to handle various maintenance and operational tasks, improving maintenance efficiency without requiring separate specialized communication channels for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If remote control emulation is implemented, then remote troubleshooting capability improves, but processing overhead and response time may worsen

Engineering Contradiction:
Improveremote access capabilityVSAvoidcommand processing delay
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-processing and buffering remote control commands before they need to be executed. The system prepares command queues, pre-loads necessary software components, and anticipates upcoming operations, thereby reducing the actual execution delay when remote commands are received and processed, improving both ease of operation and response time.

Inventive Principle:
Principle #10Preliminary action
