Packaging Opening Detection Casing With Detachable Secure Hold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing opening detection devices for packaging materials face challenges in securely attaching to the circuit pattern without the need for additional fixing members, leading to increased mounting time and effort, and potential detachment due to force applied when the packaging is opened.
Innovation Solution
An opening detection device with a casing that holds the packaging material detachably, featuring a first and second casing that securely fit together, allowing easy attachment and detachment, and includes projecting portions for increased holding force without electrical contact, using elastic or high-friction materials to maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact portion is contacted with the circuit pattern to detect opening, then opening detection function is achieved, but the contact is likely to be released when force is applied to the packaging material
Solution Approach 1:
The second casing is designed to be movable relative to the first casing, allowing the opening detection device to dynamically adapt to forces applied during packaging opening. The movable structure enables the device to maintain contact with the circuit pattern while accommodating the mechanical stress of opening operations.
2Reliability
If additional fixing members are used to firmly contact the contact portion and circuit pattern, then contact reliability is improved, but mounting time and effort increase
Solution Approach 1:
The fixing function is merged into the casing structure itself through the movable second casing, eliminating the need for separate fixing members. The casing integrates both the detection function and the securing function, allowing the device to be mounted and secured in a single operation.
Solution Approach 2:
The movable second casing automatically provides the fixing action through its own movement and positioning, without requiring external fixing members or additional mounting steps. The structure self-adjusts to maintain reliable contact during the opening process.
3Ease of operation
If the casing is made detachable for easy attachment and detachment, then ease of operation is improved, but the holding force may be insufficient to prevent accidental detachment
Solution Approach 1:
The movable second casing provides a dynamic holding mechanism that maintains sufficient holding force through its positioned configuration. The movability allows for easy attachment and detachment operations while the engaged position provides stable holding during normal use.

AI summary
An opening detection device includes a casing that is to be attached to a packaging material whose electric characteristics change when the packaging material is opened, and a detection section detecting opening of the packaging material based on change of the electric characteristics. The casing includes a holding structure with which the packaging material is detachably held.
