Storage Bag Release Sheet Color Contrast Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paper sheet storing devices often result in unsealed storage bags due to operators forgetting to remove the release sheet from the adhesive portion during attachment, leading to improper sealing upon detachment.
Innovation Solution
A storage bag design with a release sheet that is detachably adhered to the adhesive portion, featuring a distinct color, opaque material, and a message to prompt removal, along with a release sheet detector and notifier in the storing device to ensure the sheet is removed before attachment, preventing the adhesive from adhering incorrectly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the release sheet is used to protect the adhesive portion, then the adhesive portion is protected from contamination, but the operator may forget to remove the release sheet leading to unsealed storage bags
Solution Approach 1:
The release sheet is made with a color different from the body (e.g., red release sheet on transparent body) to create visual contrast. This color differentiation serves as a persistent reminder to operators to remove the release sheet before sealing, directly addressing the forgetting problem while maintaining protection functionality
Solution Approach 2:
The storing device includes a release sheet detector that provides feedback when the release sheet is still attached. The detector uses optical sensors to sense the presence of the release sheet and notifies the operator through display or audio signals, ensuring the release sheet is removed before sealing occurs
Solution Approach 3:
The system performs preliminary detection of the release sheet presence before the sealing operation is executed. The detector checks whether the release sheet is attached, and only when it detects the sheet is removed does the system permit or automatically perform the sealing action, preventing unsealed bags from the outset
2Reliability
If the release sheet covers the adhesive portion, then the adhesive portion is protected, but the operator lacks visual cues to remind removal
Solution Approach 1:
The release sheet uses a color different from the body to create visual contrast and serve as a reminder. This color differentiation maintains adhesive protection functionality while simultaneously providing persistent visual information to operators about the presence of the release sheet that needs removal
Solution Approach 2:
The release sheet detector provides feedback information about the release sheet's presence or absence. This feedback mechanism compensates for the information loss caused by the release sheet covering the adhesive portion, giving operators explicit notification when removal is needed
3Reliability
If a release sheet detector and notifier are added to the storing device, then operators are reminded to remove the release sheet, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical detection systems with optical sensing. The release sheet detector uses optical sensors that detect the presence of the release sheet through its light-absorbing or light-blocking properties, simplifying the detection mechanism compared to mechanical switches or sensors while maintaining reliable detection functionality
Solution Approach 2:
The release sheet itself serves as part of the detection system by having optical properties (color, opacity) that enable the detector to sense its presence. The release sheet's material characteristics are leveraged for detection purposes, reducing the need for separate complex detection mechanisms

AI summary
A storage bag includes a body having a top opening, a first fitting portion and a second fitting portion disposed in the vicinity of the opening of the body, an adhesive portion disposed on an inner surface of the body in the vicinity of the first fitting portion, the adhesive portion being configured to seal the body, and a release sheet detachably adhering to the adhesive portion, the release sheet protecting the adhesive portion, and the release sheet covers at least one of the first fitting portion and the second fitting portion.
