Solution Overview

Problem

Existing converters for driving lighting means, such as LED converters, face increased costs and sizes due to the inclusion of both wireless and wired communication capabilities, despite not all communication features being utilized in practical use.

Innovation Solution

A modular communication adaptor is introduced, comprising a transmission antenna, wired control interface, and control circuitry that converts wireless and wired signals, powered by the wired control interface, allowing for a compact design that does not require a separate power supply and uses engagement means with the converter for strain relief.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a converter is provided with both wireless and wired communication means, then communication versatility is improved, but cost and size increase

Engineering Contradiction:
Improvecommunication versatilityVSAvoidconverter size
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication system is segmented into a converter unit and a separate communication adaptor. The adaptor contains the wireless communication means (NFC antenna and control circuitry) and can be detached or attached as needed. This allows the converter to have wireless capability only when the adaptor is present, reducing size and cost when the adaptor is not used.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wireless communication functionality is extracted from the converter and placed into a separate communication adaptor. This extraction allows the converter to be sold and used without the wireless capability, reducing its size and cost, while still offering wireless functionality when needed through the adaptor.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If a converter is provided with both wireless and wired communication means, then communication versatility is improved, but manufacturing cost increases

Engineering Contradiction:
Improvecommunication versatilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The communication system is divided into separate manufacturing units: the converter and the communication adaptor. This segmentation allows manufacturers to produce converters at a lower base cost and only add the more expensive wireless communication components when customers require that functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The communication adaptor serves multiple functions: it provides wireless communication capability, acts as a strain relief module for power supply wiring, and can be mechanically attached to the converter. This multi-functionality justifies the additional cost by providing multiple benefits from a single component.

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

3Device complexity

If the communication adaptor is powered by the wired control interface, then device complexity is reduced, but power availability is constrained

Engineering Contradiction:
Improvepower supply structureVSAvoidpower availability
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The communication adaptor is designed to be self-powered by drawing power from the wired control interface terminals. It uses the existing DALI protocol power supply (non-zero voltage in quiescent state) to power its own control circuitry and wireless communication functions, eliminating the need for a separate power supply unit.

Inventive Principle:
Principle #25Self-service
