Solution Overview

Problem

Current emergency drivers for emergency lighting systems are costly and complex due to the need for multiple actuators and communication interfaces, which increases component density and manufacturing costs.

Innovation Solution

A method and emergency driver configuration that utilize a single test button with a double assignment of functions, allowing users to set and adjust the emergency lighting operation duration by inputting specific actuation patterns, thereby eliminating the need for additional switches or communication chips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple actuators (buttons and switches) are added to emergency driver for setting and adjusting functions, then the functionality and ease of operation are improved, but the component density and manufacturing cost increase

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The test button is assigned multiple functions: it serves both as a test function button and as a means for setting the emergency lighting operation duration. By detecting different actuation patterns (single press vs. prolonged press), the same physical component performs multiple configuration tasks, eliminating the need for separate actuators for each function.

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

Solution Approach 2:

The patent combines the test function and the duration setting function into a single button interface. The controller merges the interpretation of button presses into a unified system that distinguishes between test commands and configuration commands based on press duration, thereby reducing the total number of physical components.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If NFC or DALI communication interfaces are integrated into emergency driver for remote control, then the adaptability and ease of operation are improved, but the component density and manufacturing cost greatly increase

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces expensive communication interfaces (NFC, DALI) with a simple, low-cost button press mechanism. The button-based configuration method uses basic electrical contacts and control logic that are already present in the emergency driver, avoiding the need for additional communication chips and reducing manufacturing costs while maintaining sufficient functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The emergency driver provides self-configuration capability through its existing test button, allowing users to set the operation duration without requiring external communication devices or additional interfaces. The system serves itself by using its own built-in components for both testing and configuration purposes.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If multiple actuators are added to emergency driver for setting functions, then the ease of operation is improved, but the manufacturing cost and component density increase

Engineering Contradiction:
Improveease of operationVSAvoidease of manufacture
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The test button performs multiple functions including testing the emergency lighting system and configuring the operation duration. This multi-functionality reduces the total number of components that need to be manufactured, assembled, and tested, thereby simplifying the manufacturing process and reducing costs.

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

Solution Approach 2:

The patent extracts the configuration function from separate physical actuators and integrates it into the existing test button functionality. By removing the need for additional buttons and switches, the manufacturing process is simplified, focusing only on the essential test button and its control logic.

Inventive Principle:
Principle #2Taking out (Extraction)
