Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inspection methods for ensuring proper sealing of boxes in blinded clinical trials are labor-intensive, time-consuming, and prone to human error, requiring manual counting and verification of sealing stickers on large batches of packaging.
Innovation Solution
A tamper seal detection system comprising a housing with adjustable sensors and a push guide assembly, controlled by an electronic controller, to accurately detect and verify the presence and position of sealing stickers on packaging boxes, automating the inspection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual counting and verification of sealing stickers is used, then inspection can be performed with simple equipment, but the process is labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated optical sensing system. Sensors detect the presence and position of sealing stickers on packaging boxes, and an electronic controller automatically verifies proper sealing, eliminating the need for manual counting and verification while significantly increasing inspection speed.
Solution Approach 2:
The inspection system performs self-verification by automatically detecting and validating sealing sticker placement. The system compares detected sticker positions against predefined criteria and can automatically reject improperly sealed boxes, enabling the system to inspect itself without human intervention.
2Reliability
If manual inspection of sealing stickers is performed, then equipment costs are low, but human error increases
Solution Approach 1:
The patent replaces human inspectors with automated optical sensors and electronic controllers that objectively detect and verify sealing sticker placement. This eliminates subjective human judgment and potential errors, providing consistent, accurate inspection results regardless of inspector fatigue or training levels.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors continuously monitor sealing sticker placement and the electronic controller compares detected positions against acceptance criteria. The system provides immediate feedback by indicating pass/fail status and can trigger automatic rejection of defective packages, ensuring high inspection reliability.
3Reliability
If entire batches are re-inspected due to sticker count discrepancies, then thorough verification is achieved, but time consumption increases significantly
Solution Approach 1:
The patent performs preliminary inspection of each packaging box as it passes through the inspection zone, detecting sealing sticker presence and position before the box leaves the production line. This real-time inspection prevents the need for subsequent batch re-inspection by identifying and isolating defective packages immediately.
Solution Approach 2:
The system extracts and inspects each sealing sticker individually using optical sensors, separating the inspection function from batch processing. By examining each package independently in real-time, the system identifies specific defective items without requiring re-inspection of entire batches, saving significant time while maintaining verification thoroughness.

AI summary
A tamper seal detection system for detecting a sealing sticker on a packaging box incudes a housing at least partially bounding an inspection zone, the inspection zone being configured to receive the packaging box. A first sensor is configured to detect the presence of the first sealing sticker located on the packaging box when the packaging box is received within the inspection zone. A push guide is movable relative to the inspection floor between a first position and a spaced apart second position and can be used to push the packaging box out of the inspection zone.
