Solution Overview

Problem

Existing illuminated containers do not effectively utilize the advantages of OLEDs for planar illumination and lack an illuminated base plate that can provide controlled and ornamental lighting effects.

Innovation Solution

A transparent container with an illuminated base plate using LED or OLED lighting devices, designed for controllable illumination, where the OLED lighting device is integrated with a semi-transparent coating on a thin plastic base, and the LED lighting device uses light guides and diffusers for even illumination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a traditional light source (lamp or LED) is used to illuminate the container interior, then the container can be illuminated, but the illumination is not planar and cannot achieve thin, ornamental lighting effects

Engineering Contradiction:
Improveplanar illumination qualityVSAvoidlighting device structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical light sources (lamps, LEDs with reflectors) with an OLED (organic light-emitting diode) that provides direct planar illumination. This substitution eliminates the need for complex optical components like reflectors and diffusers, achieving thin, ornamental lighting effects while maintaining illumination quality.

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

Solution Approach 2:

The OLED lighting device can display different colors and patterns, enabling ornamental lighting effects. The semi-transparent coating on the base plate allows these color changes to be visible from the outside, creating decorative patterns and logos that enhance the container's aesthetic appeal.

Inventive Principle:
Principle #32Color changes

2Illumination intensity

If an illuminated display is attached to the container wall, then lighting effects can be achieved, but the base plate cannot provide stable placement and the lighting is not from below

Engineering Contradiction:
Improvelighting effect qualityVSAvoidcontainer placement stability
Core Design Contradiction:
Illumination intensityVSStability of the object's composition

Solution Approach 1:

The patent moves the lighting device from the container wall (vertical dimension) to the base plate (horizontal dimension), illuminating from below rather than from the side. This dimensional change allows the base plate to serve dual functions: providing stable placement through its weight and structure, while simultaneously generating ornamental lighting effects from underneath.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a thick base plate with cavity is used to house lighting components, then lighting functionality is achieved, but the container height increases and the design becomes less elegant

Engineering Contradiction:
Improvelighting functionalityVSAvoidcontainer height
Core Design Contradiction:
Adaptability or versatilityVSLength of stationary object

Solution Approach 1:

The patent uses a thin base plate with a semi-transparent coating instead of a thick base plate with a cavity housing. The OLED technology enables the lighting function to be integrated directly into the thin base plate structure, eliminating the need for a deep cavity and reducing the overall container height while maintaining lighting functionality.

Inventive Principle:
Principle #30Flexible shells and thin films

4Illumination intensity

If traditional lighting devices are used, then illumination can be provided, but energy consumption is high and the lighting is not controllable

Engineering Contradiction:
Improveillumination capabilityVSAvoidenergy consumption
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent employs an OLED with controllable parameters including brightness, color, and activation timing. The OLED can be activated only when needed (e.g., when the container is picked up or during specific time periods), significantly reducing energy consumption compared to traditional lighting devices that operate continuously or lack control mechanisms.

Inventive Principle:
Principle #35Parameter changes
