Solution Overview
Problem
There is no adequate method to inspect battery products for deformation on an industrial scale, which can lead to reduced performance or dysfunctionality due to curving or bending during the manufacturing process.
Innovation Solution
A computer-implemented method for inspecting battery products by capturing side views from different directions, determining deformation based on the evaluation of outermost boundaries using minimum bounding boxes, and comparing areas to detect deviations from reference values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional inspection methods are used, then simplicity of implementation is maintained, but inspection capability and reliability are insufficient for industrial-scale deformation detection
Solution Approach 1:
The patent transitions from traditional single-point or surface inspection to three-dimensional inspection by capturing side views from multiple directions. Multiple cameras are positioned to capture images from different angles (front, rear, left, right sides), creating a three-dimensional inspection space that enables comprehensive deformation detection throughout the battery product volume.
Solution Approach 2:
The inspection process is segmented into multiple independent viewing directions, with each camera capturing side views from its specific angle. The system divides the inspection task into separate directional inspections (front, rear, left, right) and then integrates these segmented views through image processing to achieve complete three-dimensional deformation analysis.
2Measurement precision
If comprehensive multi-directional inspection is implemented, then deformation detection accuracy is improved, but processing time and computational load increase
Solution Approach 1:
The patent performs preliminary actions by pre-defining reference side views from standard battery products and establishing minimum bounding boxes for comparison. These reference models are prepared in advance, allowing the inspection system to directly compare captured images against pre-established standards without performing complex calculations during the actual inspection process.
Solution Approach 2:
The system extracts only the essential features needed for deformation detection - specifically the minimum bounding box dimensions and outmost boundaries - from the complete side view images. By focusing only on these extracted geometric features rather than analyzing entire images, the system achieves precise deformation measurement while minimizing processing time and computational requirements.
3Reliability
If detailed boundary evaluation is performed, then deformation detection accuracy is improved, but hardware requirements and system cost increase
Solution Approach 1:
The patent replaces complex mechanical measurement systems with optical imaging and computational analysis. Instead of using physical probes or contact-based measurement devices, the system uses cameras to capture side views and employs image processing algorithms to evaluate boundaries and detect deformations, thereby reducing mechanical complexity while maintaining high inspection reliability.
Solution Approach 2:
The system creates two-dimensional side view images as copies of the three-dimensional battery product from multiple angles. These image copies serve as digital representations that can be analyzed without physically manipulating the product, enabling detailed boundary evaluation through software processing rather than complex hardware measurement systems.

AI summary
A computer-implemented method for inspection of a battery product, the method comprising: receiving, from a first detection unit, a first side view of the battery product captured in a first direction with respect to the battery product; and determining, from the first side view, a deformation of the battery product based on an evaluation of outmost boundaries of the battery product in the first side view.
