Solution Overview

Problem

Existing shoe display and storage solutions fail to maintain optimal internal temperature and humidity, leading to potential deformation or contamination of shoes, and limit display effectiveness by restricting viewing angles and illumination options.

Innovation Solution

A show case with a body and moving body that forms an accommodation space, allowing air circulation and illumination control, along with a controller that recommends suitable illumination based on object images, enhancing display and management effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the container uses a transparent door panel for display, then the visibility of the shoe is improved, but the internal temperature and humidity cannot be controlled

Engineering Contradiction:
ImprovevisibilityVSAvoidinternal temperature control
Core Design Contradiction:
Illumination intensityVSTemperature

Solution Approach 1:

The container is divided into a sealed accommodation space for temperature and humidity control, and a separate door panel system with transparent and opaque portions. This segmentation allows the display function to be separated from the environmental control function, resolving the contradiction between visibility and temperature control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door panel has different transparency properties in different regions - transparent portions for display and opaque portions for sealing. This local differentiation allows specific areas to serve different functions, maintaining both visibility where needed and sealing where environmental control is required.

Inventive Principle:
Principle #3Local quality

2Quantity of substance

If the container ventilates internal air to outside air, then air circulation is improved, but the internal humidity cannot be maintained

Engineering Contradiction:
Improveair circulationVSAvoidhumidity maintenance
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The harmful function of uncontrolled ventilation is extracted and replaced by a controlled air circulation system. The blowing part creates a defined air flow path that circulates air within the sealed accommodation space without exchanging it with external air, thereby maintaining humidity while still achieving air movement.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The blowing part acts as an intermediary device that mediates between the need for air circulation and the need for humidity maintenance. It generates controlled air flow that circulates internally without breaching the sealed environment, resolving the contradiction between these two requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If the show case uses a turntable for product display, then the display effect is improved, but the structural stability is reduced

Engineering Contradiction:
Improvedisplay effectVSAvoidstructural stability
Core Design Contradiction:
Illumination intensityVSStability of the object's composition

Solution Approach 1:

The show case incorporates a turntable that enables dynamic rotation of products for enhanced display. The rotational mechanism allows the accommodation space to present products from multiple angles, improving display effectiveness while maintaining structural integrity through controlled movement.

Inventive Principle:
Principle #15Dynamics

4Illumination intensity

If the show case provides multi-angle viewing, then the display effectiveness is improved, but the device complexity increases

Engineering Contradiction:
Improvedisplay effectivenessVSAvoidviewing structure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The show case utilizes the rotational dimension of the turntable to provide multi-angle viewing capabilities. By rotating the accommodation space around a vertical axis, products become visible from multiple directions without requiring complex multi-faceted structures, achieving enhanced display effectiveness through dimensional movement rather than structural complexity.

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