1Reliability

If a Zener diode is added to divert static electricity, then the light-emitting device gains electrostatic protection, but the device occupies more space and requires additional processing

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The substrate integrates multiple functions: it serves as both the mounting platform for the light-emitting element and as an electrostatic diverter through embedded variable resistors. This merging of structural and protective functions eliminates the need for separate Zener diode components, thereby protecting against static electricity while occupying minimal space.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The substrate is designed with multi-functionality, acting simultaneously as a mechanical support structure and an electrostatic protection system. The variable resistors are incorporated directly into the substrate layers, enabling the substrate to perform both structural and electrostatic diversion roles without requiring additional dedicated components.

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

If a Zener diode is added to divert static electricity, then the light-emitting device gains electrostatic protection, but the manufacturing process becomes more complex

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The electrostatic protection components (variable resistors) are merged into the substrate manufacturing process itself. The substrate is formed with embedded variable resistors as integral parts of its layered structure, eliminating the need for separate assembly steps for installing Zener diodes and simplifying the overall manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The variable resistors are incorporated into the substrate during the substrate formation process itself, before the light-emitting element is mounted. This preliminary integration of protective components into the base structure eliminates subsequent assembly steps and reduces manufacturing complexity.

Solution Approach 1:

The variable resistors and insulation portions are arranged in vertical layers that penetrate through the substrate thickness, utilizing the third dimension (depth) rather than expanding the horizontal footprint. This vertical integration allows electrostatic protection components to be embedded within the substrate volume, achieving minimal space occupation while maintaining structural integrity.
