Design Assistance Device for Clear 3D Item Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing design assistance tools fail to clearly display the shapes and specification information of multiple items in an item group, making it difficult for users to easily view and understand the design, especially when items overlap or have complex orientations.
Innovation Solution
A design assistance device that acquires three-dimensional data of an item group, generates two-dimensional display data showing the appearance and specification information of each item, and determines the display mode based on the shape and relative positions of items to prevent obstruction, allowing users to view items clearly from any desired observation direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple items are displayed in a two-dimensional view from a single observation direction, then the display shows the overall item group appearance, but items with complex orientations or overlapping positions may obstruct each other, making specification information unclear
Solution Approach 1:
The patent applies dimensionality change by switching from a single two-dimensional observation direction to multiple observation directions. The system determines an optimal observation direction for each item based on its three-dimensional shape and orientation, then displays each item in its own optimized two-dimensional view. This resolves the obstruction problem by allowing each item to be viewed from its best angle without being blocked by other items, while still presenting all items on a two-dimensional display device.
Solution Approach 2:
The patent segments the display of the item group by determining and applying different observation directions for different items. Instead of using a single uniform observation direction for all items, the system divides the display into multiple item-specific views, each optimized for its particular geometry and orientation. This segmentation allows each item's specification information to be clearly displayed without interference from adjacent items.
2Ease of operation
If the display mode is fixed for all items, then the display process is simple, but items with different shapes and orientations cannot be optimally displayed, reducing viewability
Solution Approach 1:
The patent applies dynamics by making the observation direction adaptive rather than fixed. The system dynamically determines the optimal observation direction for each item based on its three-dimensional shape and orientation characteristics. This dynamic adjustment allows the display to adapt to each item's specific geometry, providing optimal viewability for diverse item types while automating the complexity through algorithmic determination rather than manual configuration.
Solution Approach 2:
The patent changes the parameter of observation direction based on item-specific characteristics. By analyzing the three-dimensional shape and orientation of each item, the system selects appropriate observation direction parameters that optimize the two-dimensional projection for clarity. This parameter adjustment ensures that items with different geometries are displayed in their most viewable orientations, improving overall ease of viewing.
