Screw Nut Barcode Segments for Multi-Angle Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw nuts with barcode patterns on their faces face challenges in accessibility and protection due to obstruction by threaded rods during installation, leading to cumbersome alignment and potential mechanical damage.
Innovation Solution
A screw nut design featuring at least three identical barcode patterns on a ring-shaped face surrounding the through hole, ensuring accessibility from various angles and protection from mechanical damage, with the option for additional patterns on a second face for dual configuration compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single barcode pattern is placed on a face of the screw nut, then the data can be stored on the nut, but the threaded rod obstructs the view and requires cumbersome alignment of the barcode reader
Solution Approach 1:
The patent applies local quality by placing multiple barcode patterns at different locations on the nut face, specifically at different angular positions around the circumference. This ensures that at least one barcode pattern is always accessible from any viewing angle, eliminating the need for precise alignment during operation.
Solution Approach 2:
The patent transitions from a single linear barcode to multiple barcodes arranged in a circular pattern around the nut face. This dimensional change from one-dimensional linear arrangement to two-dimensional circular distribution allows the barcode information to be accessed from any angular position, solving the alignment problem.
2Loss of information
If the barcode is placed on the screw nut face, then data can be read optically, but the barcode is vulnerable to mechanical damage during installation
Solution Approach 1:
The patent applies preliminary action by pre-positioning multiple barcode patterns on the nut face before installation. The redundant arrangement ensures that even if some barcodes are damaged during installation, the data remains accessible through the undamaged barcodes, protecting against mechanical damage in advance.
Solution Approach 2:
The patent provides beforehand cushioning against mechanical damage by creating redundancy through multiple barcode patterns. If one barcode is damaged during installation, the other barcodes serve as a backup, cushioning against complete data loss and ensuring continuous reliability.
3Loss of information
If multiple identical barcode patterns are placed on the first face of the screw nut, then accessibility and protection are improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies copying by creating multiple identical barcode patterns on the nut face. These barcodes are replicated at different angular positions, allowing the same data to be read from any position. The copying process uses standard marking techniques to reproduce identical barcode images at multiple locations.
Solution Approach 2:
The patent applies universality by making each barcode pattern serve the same function - providing data read-out accessibility. All barcode patterns are identical and can be read by any standard barcode reader positioned at any angular location, making the system universally accessible regardless of viewing angle.
