Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the barcode is provided at multiple locations on the battery cell to allow reading through one reading unit, then the barcode can be read regardless of position, but it increases management complexity and cost
Solution Approach 1:
The patent applies dimensionality change by arranging multiple reading units in different spatial positions (first reading unit and second reading unit at different locations) to read barcodes from multiple angles simultaneously. This allows a single barcode to be read regardless of its position on the battery cell, eliminating the need to print multiple barcodes at different locations while maintaining adaptability.
2Adaptability or versatility
If the barcode is provided at multiple locations on the battery cell to allow reading through one reading unit, then the barcode can be read regardless of position, but it increases cost
Solution Approach 1:
The patent uses spatial arrangement of reading units in different dimensions/positions to achieve universal barcode reading capability. Instead of increasing the quantity of barcodes by printing them at multiple locations, the solution arranges reading units at different spatial positions to read the same single barcode from various angles, thereby reducing the quantity of barcodes needed.
3Adaptability or versatility
If the battery cell tracking device is configured to read barcodes in various directions to handle non-fixed positions, then barcode reading is possible, but the device configuration becomes complicated
Solution Approach 1:
The patent resolves device complexity by arranging reading units at different fixed spatial positions rather than using a single reading unit that must rotate or adjust. The first reading unit and second reading unit are positioned at different locations to read barcodes from different directions simultaneously, achieving directional adaptability through spatial distribution rather than mechanical adjustment.
Solution Approach 2:
The patent applies preliminary action by pre-positioning multiple reading units at optimized locations before operation. The reading units are arranged in advance at specific positions (first reading unit and second reading unit) to cover different reading angles, eliminating the need for real-time adjustment or complex configuration during operation.
