Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cylindrical battery side surface inspection devices require rotation or rolling to capture images, leading to image noise and degraded quality.
Innovation Solution
A side surface inspection device with multiple mirrors and a camera that reflects light across different areas of the battery's side surface without rotating or rolling, forming a single image of all areas simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the cylindrical battery is rotated or rolled by 360 degrees to obtain an image of the side surface, then all areas of the side surface can be captured, but image noise is generated and image quality is degraded
Solution Approach 1:
The patent transitions from a one-dimensional rotation/rolling approach to a two-dimensional optical path approach by arranging multiple cameras and mirrors in space. The mirrors reflect light from different side surface areas to multiple cameras positioned at different locations, enabling comprehensive side surface imaging without mechanical rotation of the battery.
Solution Approach 2:
The side surface inspection is divided into multiple discrete areas (first area, second area, third area, fourth area), with each area captured by a dedicated camera-mirror combination. This segmentation allows simultaneous capture of all areas without the need to rotate the battery, thereby preventing image noise while maintaining complete side surface coverage.
2Adaptability or versatility
If the cylindrical battery is rotated or rolled to perform exterior inspection, then complete side surface inspection is achieved, but detectability is degraded due to image noise
Solution Approach 1:
The patent replaces the mechanical rotation/rolling system with an optical system consisting of mirrors and multiple cameras. Instead of mechanically moving the battery to inspect different areas, the optical system redirects light from all side surface areas to stationary cameras, eliminating mechanical-induced image noise while maintaining complete inspection capability.
Solution Approach 2:
Mirrors are introduced as intermediary elements to redirect light from different side surface areas to the cameras. These mirrors act as mediators that enable comprehensive imaging without requiring the battery to be rotated or rolled, thereby preserving image quality and detectability while achieving complete side surface inspection.
