Sticky Interleaf Sheet Cutout Pattern for Insertion Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sticky interleaf sheets and regular interleaf sheets are often mistakenly inserted incorrectly due to their similar shapes, leading to improper protection of components in trays.
Innovation Solution
The sticky interleaf sheet features a cutout portion or hole with a concavo-convex pattern on its edge, including protrusions and grooves of varying sizes and shapes, which allows for machine vision differentiation from regular interleaf sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sticky interleaf sheets and regular interleaf sheets have similar shapes, then manufacturing cost is reduced and ease of manufacture is improved, but incorrect insertion occurs and reliability deteriorates
Solution Approach 1:
The patent applies asymmetry by introducing a cutout portion with a concavo-convex pattern on the sticky interleaf sheet that is not present on regular interleaf sheets. This asymmetric feature creates a visual distinction that prevents incorrect insertion while maintaining the same basic rectangular shape and size for both sheet types, thus preserving ease of manufacture while improving reliability.
2Reliability
If a cutout portion with concavo-convex pattern is added to the sticky interleaf sheet, then reliability is improved by preventing incorrect insertion, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the edge of the sticky interleaf sheet into distinct segments: a cutout portion with a concavo-convex pattern and a non-cutout portion without the pattern. This segmentation creates a clear visual signature that enables machine vision systems to distinguish sticky interleaf sheets from regular interleaf sheets, improving reliability while keeping the overall structure simple.
3Measurement precision
If the cutout portion width is within 177-183 mm, then machine vision detection precision is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies parameter changes by specifying a particular width range for the cutout portion (177-183 mm) that optimizes machine vision detection precision. This parameter optimization ensures that the concavo-convex pattern is large enough to be reliably detected by machine vision systems while maintaining manufacturability within standard tolerances, balancing measurement precision with manufacturing precision requirements.

AI summary
A disclosed sticky interleaf sheet including an edge, has a cutout portion in which a part of the edge is concave or a hole in the sticky interleaf sheet resides, wherein the cutout portion may include a concavo-convex pattern.
