Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for generating reference images of products from multiple orientations require manual adjustment of product orientation, which is time-consuming and labor-intensive.
Innovation Solution
A registration system utilizing a plate-shaped member with a hole penetrating from front to back, combined with front and back cameras, to capture and register product images from different orientations efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple reference images are captured by manually changing product orientation, then accurate product recognition from multiple orientations is achieved, but time consumption and labor effort increase extremely
Solution Approach 1:
The patent replaces the manual mechanical system of changing product orientation with an optical system using a transparent plate and multiple cameras. The plate allows light transmission from both front and back, enabling simultaneous capture of product images from multiple orientations without physical manipulation, thus resolving the contradiction between measurement precision and time loss.
Solution Approach 2:
The patent introduces a new dimension by using a transparent plate that allows viewing and capturing from both front and back sides simultaneously. This dimensional approach enables multiple orientation captures without sequential manual adjustment, achieving high recognition accuracy while eliminating time-consuming manual operations.
2Productivity
If multiple cameras are used to capture product images from front and back, then multiple reference images are generated efficiently, but device complexity increases
Solution Approach 1:
The transparent plate serves multiple functions: it supports the product, allows light transmission from both sides, and provides a stable positioning structure. This multi-functionality reduces the need for additional complex components while enabling efficient multi-orientation image capture, resolving the contradiction between productivity and device complexity.
3Extent of automation
If a transparent plate with hole is used for product placement, then automatic multi-orientation capturing is enabled, but manufacturing precision of the plate structure is required
Solution Approach 1:
The patent specifies precise parameters for the transparent plate including hole diameter (5-20mm), hole position (centered or offset by 1-5mm), and plate thickness (1-5mm). These parameter specifications enable automatic multi-orientation capturing while providing clear manufacturing guidelines to control the required precision, resolving the contradiction between automation extent and manufacturing precision.
