Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for allocating short addresses in illumination systems controlled via a DALI bus require operator intervention, which is time-consuming and prone to errors, especially in larger systems.

Innovation Solution

A method utilizing a localization device that automatically determines the location of illumination components via a search algorithm and allocates short addresses without operator presence, using tags to identify activated components and a portable computer to transmit DALI commands for address allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual allocation of short addresses is used, then operator control and verification are improved, but setup time and complexity increase significantly

Engineering Contradiction:

Improveallocation accuracyVSAvoidsetup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The illumination components automatically generate their own short addresses by detecting their physical location in the sequence and using it as the address value, eliminating the need for operator intervention in the address allocation process

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of operator input and verification is replaced by an automated electronic system where components self-identify through sequential signaling and the control device automatically assigns addresses based on detection order

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual input of short addresses is required, then operator verification is improved, but error susceptibility increases

Engineering Contradiction:

Improveallocation accuracyVSAvoidoperation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system eliminates manual input operations entirely by having illumination components self-identify through automatic signaling and the control device automatically allocate addresses without human intervention, removing the source of manual errors

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

Illumination components provide feedback signals when activated, allowing the control device to detect which component is active and automatically assign the corresponding short address based on the detected sequence position

Inventive Principle:

Principle #23Feedback

3Productivity

If automated allocation is implemented, then setup time is reduced, but system complexity increases

Engineering Contradiction:

Improveallocation speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The automated system uses electronic signaling and digital processing instead of manual mechanical operations, where the control device automatically detects component positions and assigns addresses through algorithmic processes rather than human intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system divides the initialization process into distinct phases: long address generation, sequential signaling, location detection, and short address allocation, allowing each function to be performed independently and systematically

Inventive Principle:

Principle #1Segmentation
