Innovation Solution

A compact, lightweight image projector with a plug-in outlet or USB port for power, utilizing multiple LEDs for sequential flashing and color-changing effects without motors, and geometric optics for image projection, allowing for direct power from outlets or USB ports without wires, and incorporating principles from various LED light patents for power efficiency and cost savings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If battery operation is used to power LEDs, then portability is improved, but frequent battery changes are required due to high current consumption

Engineering Contradiction:
ImproveportabilityVSAvoidbattery change frequency
Core Design Contradiction:
Length of moving objectVSLoss of time

Solution Approach 1:

The patent replaces the mechanical battery system with an electrical plug-in power system. The device can be connected to AC power outlets or USB ports, eliminating the need for battery installation and replacement. This substitution resolves the contradiction by maintaining portability while eliminating the time loss associated with frequent battery changes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Power

If wired AC connection with adaptor or transformer is used, then power supply is improved, but wires cause safety hazards and are difficult to handle

Engineering Contradiction:
Improvepower supplyVSAvoidwire-related safety hazards
Core Design Contradiction:
PowerVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the wire component from the power connection system. By designing the device with a built-in plug that connects directly to outlets or USB ports, the hazardous wire is eliminated while maintaining adequate power supply to multiple LEDs.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces wireless power transmission as an intermediary between the power source and the device. Through plug-in connections to AC outlets or USB ports, power is transmitted without exposed wires, eliminating safety hazards while maintaining power supply capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If motors and magnetic coils are used to create moving effects, then visual interest is improved, but device complexity and cost increase

Engineering Contradiction:
Improvemoving effectsVSAvoidmotor and magnetic coil system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical motors and magnetic coils with electronic control of LED elements. By individually controlling multiple LEDs through electronic circuits, the device creates moving light effects, color changes, and patterns without requiring complex mechanical or electromagnetic components.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent achieves moving effects by changing the operational parameters of LEDs - specifically their brightness, color, and timing. By varying these parameters across multiple LEDs in sequence or simultaneously, the device creates dynamic visual effects without mechanical moving parts.

Inventive Principle:
Principle #35Parameter changes

4Illumination intensity

If multiple LEDs with high current consumption are used, then illumination intensity is improved, but energy consumption increases requiring frequent battery changes

Engineering Contradiction:
ImproveLED brightnessVSAvoidcurrent consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent employs periodic operation of LEDs through blinking, flashing, and sequential lighting patterns. By alternating between on and off states, the average power consumption is reduced while maintaining visual interest and perceived brightness through persistence of vision effects.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent divides the illumination task across multiple individual LED elements rather than using a single high-power LED. Each LED can be controlled independently with lower current, and by distributing the total light output across multiple segments, the system achieves high illumination intensity while managing power consumption through selective activation.

Inventive Principle:
Principle #1Segmentation
