Display cabinet and control method of the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional display cabinets cannot provide an interactive and comprehensive viewing experience of exhibits, especially valuable items like antiques and jewelry, as they are typically static and require professional modeling or high-cost 3D cameras for 3D modeling, posing risks during transportation and being costly.
Innovation Solution
A display cabinet with a rotatable tray, a first camera for capturing images from different angles, and a transparent touch display screen that constructs and displays 3D models, controlled by a microprocessor to manage power states and rotation based on visitor proximity and attention, allowing visitors to interact with 3D models without professional intervention or high-performance equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If professional modeling is used to create 3D models of exhibits, then the quality of 3D models is improved, but the risk of damage to exhibits during transportation increases and the cost increases
Solution Approach 1:
The patent uses a camera to capture images of the exhibit and generates a 3D model through image processing, creating a digital copy without physical contact. This eliminates the need for physical transportation and handling of the original exhibit during the modeling process, thus reducing the risk of damage while maintaining 3D model quality.
2Manufacturing precision
If professional modeling is used to create 3D models of exhibits, then the quality of 3D models is improved, but the cost increases
Solution Approach 1:
The patent replaces the mechanical and manual professional modeling process with an automated image-based 3D reconstruction system. A camera captures multiple images of the exhibit, and a processor automatically generates the 3D model, eliminating the need for expensive professional modeling services while maintaining acceptable 3D model quality.
3Manufacturing precision
If a 3D camera is used to obtain 3D models, then the quality of 3D models is improved, but the cost increases
Solution Approach 1:
The patent uses a standard camera instead of an expensive 3D camera to capture images for 3D model generation. While individual image quality may be lower, the automated processing system compensates by combining multiple images, achieving acceptable 3D model quality at a lower cost.
4Reliability
If exhibits are statically placed in display cabinets, then the exhibits are protected, but the viewing experience is limited
Solution Approach 1:
The patent creates a 3D digital copy of the exhibit that can be viewed and interacted with from multiple angles on a transparent display screen. This allows visitors to examine the exhibit comprehensively without physically handling or moving the original, thus maintaining protection while significantly enhancing the viewing experience.
5Ease of operation
If transparent interactive screens are embedded into display cabinets, then the interactive experience is improved, but the display of real exhibits is blocked
Solution Approach 1:
The patent uses a transparent display screen that allows light to pass through, making the display content visible only in specific areas while maintaining overall transparency. This enables the real exhibit to remain visible through the transparent portions of the screen, while interactive 3D model information is displayed on the screen surface, thus preserving both the real exhibit visibility and interactive functionality.
