Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing processes for light source circuit boards struggle to distinguish between products for different applications due to similar visual appearances, leading to difficulties in identifying discrete electrical components and potential human errors during the manufacturing process.
Innovation Solution
The method involves incorporating circuit components with specific electrical circuit constants on light source circuit boards, which specify performance parameters such as color temperature, power input, or model identifiers, allowing for automatic testing and differentiation between boards, even when they appear identical. These components are strategically placed on the board to alter electrical circuit properties and are coupled with light emitting diodes, enabling precise control of light source functionality through microprocessors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discrete electrical components are used to differentiate light source products for different applications, then product functionality can be customized, but visual identification of differences becomes difficult and manual tracking during manufacturing becomes necessary
Solution Approach 1:
The patent applies color coding to circuit board components (resistors, capacitors, inductors) where different colors represent different electrical values. This allows visual identification of component specifications without reading small printed values, solving the problem of difficult visual identification while maintaining product customization through component selection.
Solution Approach 2:
The patent changes the measurable parameters of the circuit board by incorporating specific combinations of passive components with defined electrical characteristics (resistance, capacitance, inductance values). These parameter changes create distinct electrical signatures that can be automatically detected during manufacturing, replacing manual tracking methods.
2Reliability
If manual tracking and identification methods are used during manufacturing, then product differentiation is possible, but human error increases and manufacturing efficiency decreases
Solution Approach 1:
The patent replaces manual visual inspection and tracking with automated electrical measurement systems. Test equipment automatically measures the electrical characteristics of passive components on the circuit board to identify product type, eliminating human error and increasing manufacturing speed through automated processes.
Solution Approach 2:
The circuit board itself provides identification information through its electrical characteristics. The passive components are selected and positioned so that their electrical properties automatically encode the product identity, allowing the board to 'self-identify' during automated testing without requiring external tracking systems or manual intervention.
3Ease of manufacture
If identical circuit board layouts are used for different applications, then manufacturing simplicity is maintained, but product differentiation becomes difficult
Solution Approach 1:
The patent maintains identical overall circuit board layouts but introduces local variations through the selection and placement of passive components. Specific resistors, capacitors, or inductors are chosen with different electrical values at specific locations on the board, creating unique electrical signatures that enable product differentiation while preserving manufacturing simplicity through standardized board designs.
