Chuck Body Marking Layout for Hidden Product Information Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing chuck mechanisms face challenges in maintaining visibility of product information due to it being covered by jigs or top jaws during workpiece processing, making it difficult to read the engraved markings on the installation surface.
Innovation Solution
Incorporating a secondary coded marking, such as a two-dimensional code, on the side surface or non-opposing areas of the chuck body and top jaw, allowing for information retrieval using a code scanner even when the primary markings are obscured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If product information is engraved on the installation surface of the chuck body in a visually readable form, then the product information can be read by sight, but the engraved area occupies a large area on the installation surface and may be covered by jigs during workpiece processing
Solution Approach 1:
The patent applies dimensionality change by providing product information in two different forms: a first marking (engraved text) on the installation surface and a second marking (coded form such as 2D code) on the side surface of the chuck body. This allows the information to be accessible from different spatial dimensions, ensuring that at least one form remains visible during workpiece processing even if the installation surface is covered by jigs
Solution Approach 2:
The patent creates a coded copy (second marking) of the product information that can be read by code scanning devices. This coded version is provided in addition to the original engraved text (first marking), allowing information retrieval through alternative means when the original engraving becomes inaccessible due to being covered by jigs or top jaws
2Reliability
If a jig is attached to the installation surface of the chuck body for workpiece positioning, then stable workpiece processing is achieved, but the jig may cover the engraved marking and make the product information invisible
Solution Approach 1:
The patent resolves this contradiction by placing a coded version of the product information (second marking) on the side surface of the chuck body, which is a different spatial dimension from the installation surface. This ensures that while the jig covers the installation surface during stable workpiece processing, the coded information remains accessible on the side surface for retrieval by code scanning devices
3Ease of operation
If the engraved marking is made larger to ensure readability, then the product information can be read more easily by sight, but it occupies even more area on the installation surface and is more likely to be covered by jigs
Solution Approach 1:
The patent creates a coded copy (second marking) of the product information that can be read by code scanning devices. This coded version contains the same product information in a compact form that is less likely to be covered by jigs, providing an alternative readable form that does not require large area on the installation surface
Solution Approach 2:
The patent places the coded information on the side surface of the chuck body, utilizing a different spatial dimension. This allows the information to be accessible without occupying valuable area on the installation surface, and the side surface location is less likely to be covered by jigs attached to the installation surface
