Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Locating specific components on larger circuit boards with arrays of similar components is difficult and time-consuming, even with printed designations, due to the complexity and size of the boards.
Innovation Solution
Incorporating light sources arranged in arrays along orthogonal axes on the circuit board, controlled by a controller to illuminate and highlight the location of components using various techniques such as Cartesian coordinates, color, intensity, and patterns, allowing for efficient visual identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If light sources are added to highlight component locations, then component identification efficiency is improved, but device complexity increases
Solution Approach 1:
The light sources are segmented into multiple independent LED elements arranged in arrays along orthogonal axes. Each LED can be independently controlled to highlight specific component locations, allowing the system to maintain simplicity through modular segmentation while achieving effective component identification.
Solution Approach 2:
The LED arrays serve multiple functions: they highlight component locations during assembly, identify components during testing, and guide maintenance procedures. This multi-functionality justifies the added complexity by providing versatile benefits across different operational phases.
2Measurement precision
If multiple light sources are arranged in arrays along orthogonal axes, then component location identification precision is improved, but manufacturing complexity increases
Solution Approach 1:
The identification system is segmented into two independent arrays of light sources arranged along orthogonal axes. This segmentation allows each array to be manufactured and positioned separately, simplifying the overall manufacturing process while enabling precise component location identification through coordinate intersection.
Solution Approach 2:
The LEDs can change colors to indicate different component types or states. This adds a dimension of information without requiring additional light source arrays, maintaining manufacturing simplicity while enhancing identification precision through color coding.
