Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional LED light panels are used in vending machines, then illumination function is provided, but lifespan is limited and brightness is insufficient

Engineering Contradiction:
ImprovebrightnessVSAvoidlifespan
Core Design Contradiction:
Illumination intensityVSDuration of action of stationary object

Solution Approach 1:

The patent transitions from LED technology to OLED technology, fundamentally changing the material parameters and operational characteristics of the light panels. OLED panels operate at lower voltages and currents, generate less heat, and have different degradation patterns compared to LEDs, thereby simultaneously improving both brightness and lifespan

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If voltage controllers are used to adapt current for light panels, then panels can be illuminated, but energy consumption increases significantly

Engineering Contradiction:
Improveillumination capabilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The OLED panels are designed to operate directly from the vending machine's existing power supply voltage without requiring external voltage controllers or current adaptors. The panels self-regulate their power consumption based on the available voltage, eliminating the need for energy-intensive voltage conversion equipment and significantly reducing overall energy consumption

Inventive Principle:
Principle #25Self-service

3Ease of operation

If voltage controllers are incorporated to adapt current, then panels can be powered, but device bulk and manufacturing cost increase

Engineering Contradiction:
Improvepower adaptationVSAvoidbulk and cost
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the voltage controller component entirely from the system architecture. By designing OLED panels that can operate directly from the machine's power supply, the solution extracts and eliminates the problematic voltage adaptation equipment, thereby reducing device bulk, simplifying the system, and lowering manufacturing costs

Inventive Principle:
Principle #2Taking out (Extraction)

4Illumination intensity

If thick light panels are used for illumination, then sufficient light output is achieved, but space availability in the machine is reduced

Engineering Contradiction:
Improvelight outputVSAvoidpanel thickness
Core Design Contradiction:
Illumination intensityVSVolume of moving object

Solution Approach 1:

The patent employs OLED technology which inherently uses thin-film structures to generate light. These flexible, thin-film light-emitting layers can be integrated into space-constrained environments while maintaining sufficient illumination output, thereby reducing panel thickness without compromising light performance

Inventive Principle:
Principle #30Flexible shells and thin films
