Sticker Recording Sheet Bridge Portion Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sticker recording sheets with half-cut processing can cause paper jams and creases due to the half-cut portions winding around rollers or adhering to conveyance guides, leading to printing failures and poor peeling quality.
Innovation Solution
A sticker recording sheet design featuring an image-receiving paper portion with a first half-cut portion and a second half-cut portion, both with uncut bridge portions, to prevent peeling failures and creases by distributing stress and facilitating easy peeling without damaging the sticker portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If half-cut processing is performed to enable easy peeling of sticker portions, then peeling performance is improved, but the half-cut portions may turn up, wind around rollers, or adhere to conveyance guides causing paper jams
Solution Approach 1:
The patent divides the continuous recording sheet into multiple sticker portions through half-cut processing, creating separable units that can be easily peeled apart while maintaining structural integrity during conveyance
Solution Approach 2:
The patent applies different structural characteristics to different regions: the sticker portions have cut edges for easy separation, while the bridge portions maintain full structural continuity to prevent winding and paper jams during conveyance
2Reliability
If bridge portions are provided to connect sticker portions and prevent paper jams, then reliability is improved, but the sticker portions may still experience peeling failures and creases
Solution Approach 1:
The patent pre-forms the bridge portions with specific structural characteristics before peeling occurs, creating uncut regions that maintain connectivity during conveyance but allow controlled separation during peeling, preventing both paper jams and peeling failures
Solution Approach 2:
The patent modifies the structural parameters of the bridge portions by leaving them uncut while cutting the sticker portions, creating a differential structure that changes the mechanical behavior during conveyance versus peeling operations

AI summary
A sticker recording sheet includes an image-receiving paper portion having an receiving layer, an image-receiving base material, and an adhesive layer laminated on each other, and a release coated paper portion provided on a back surface side of the adhesive layer in a peelable manner, wherein the image-receiving paper portion is provided with a first half-cut portion cut in an approximately square shape, having an uncut bridge portion on at least one side of the approximately square shape, and a second half-cut portion cut from at least one side of the approximately square shape having the bridge portion toward an outer circumference of the image-receiving paper portion.
