Mailing Waybill With Segmented Bonding for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mailing waybills are difficult to remove once attached to letters or parcels, posing a risk of personal information leakage if not completely cleared.
Innovation Solution
The mailing waybill features a body with a first surface having an easily torn line, dividing it into a first area easy to tear, where personal information is recorded, and a second area, allowing for easy removal of personal information without damaging the rest of the waybill.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mailing waybill is firmly fixed to the outer surface of the letter or parcel, then the waybill is secure during mailing, but the waybill becomes difficult to remove and personal information may leak
Solution Approach 1:
The waybill is divided into two distinct areas: a first area with strong bonding for secure attachment during mailing, and a second area with weak bonding that allows easy removal. This segmentation resolves the contradiction by providing different bonding strengths in different regions of the same waybill.
Solution Approach 2:
Different bonding characteristics are applied to different parts of the waybill. The first area uses a bonding agent with strong adhesion to ensure secure attachment, while the second area uses a bonding agent with weak adhesion to facilitate easy removal. This local differentiation resolves the contradiction between secure attachment and easy removal.
2Reliability
If the mailing waybill is firmly fixed to prevent loss, then the waybill remains attached throughout mailing process, but personal information leakage risk increases when removal is needed
Solution Approach 1:
The waybill is segmented into a first area for secure mailing attachment and a second area for easy removal of personal information. This segmentation allows the waybill to remain reliably attached during mailing while enabling safe removal of sensitive information when needed.
Solution Approach 2:
The bonding surface is designed with local quality differences: the first area has strong bonding properties to prevent loss during mailing, while the second area has weak bonding properties that allow easy removal of personal information, thereby reducing leakage risk.
3Ease of operation
If the entire waybill is made easy to tear for information removal, then personal information can be cleared easily, but the waybill structure loses integrity and may fall off during mailing
Solution Approach 1:
The waybill is divided into a first area with strong bonding for structural integrity during mailing and a second area with weak bonding for easy personal information removal. This segmentation allows easy information removal without compromising overall waybill strength.
Solution Approach 2:
Different bonding strengths are applied locally: the first area maintains strong bonding to preserve waybill integrity during mailing, while the second area has weak bonding that enables easy tearing for information removal, thus resolving the contradiction between ease of removal and structural strength.

AI summary
A mailing waybill includes a body and a release film. The body has a first surface and a bonding surface opposite to the first surface. The release film is arranged on the bonding surface. The first surface has an easily torn line, such that a first area easy to tear is divided from the first surface. According to the mailing waybill in the present invention, personal information on the mailing waybill is easier to be cleared.
