Bursting Detonator for Sealed Package Breaching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealed package opening mechanisms require manual effort and time to breach, leading to slow and inconsistent opening processes, and often lack a standardized method for users to access the contents efficiently.
Innovation Solution
Incorporating a bursting detonator within the breaching bubble that ruptures under pressure, transferring energy rapidly to initiate a uniform and instantaneous edge breach, simplifying the opening process and allowing for consistent package access across different sizes and types of packages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pressure is applied to expand the breaching bubble, then the package can be opened, but the process is slow and requires significant user effort
Solution Approach 1:
The detonator is pre-filled with compressed gas and positioned within the bubble structure before sealing. The chemical energy is stored in advance, ready to be converted to mechanical energy instantaneously when activated, eliminating the need for gradual manual compression
Solution Approach 2:
The manual mechanical compression process is replaced with a chemical-to-mechanical energy conversion system. The detonator uses chemical energy storage and release to produce the bubble expansion force, substituting the user's mechanical effort with an automated energy conversion mechanism
2Reliability
If manual pressure is applied to breach the seal, then the package opens, but the process is inconsistent across different packages
Solution Approach 1:
The opening mechanism transitions from variable manual pressure application to a standardized chemical energy release process. The detonator's predetermined gas pressure and the bubble's designed structural parameters ensure consistent opening behavior across all packages, eliminating variability in user effort and technique
Solution Approach 2:
The package opening system becomes self-activating through the detonator mechanism. Once the user applies minimal activation pressure or triggers the detonator, the system automatically completes the opening process without requiring the user to control the force or duration of pressure application, ensuring consistent results
3Productivity
If a bursting detonator is added to enable rapid opening, then opening speed improves, but device complexity increases
Solution Approach 1:
The detonator is nested within the bubble structure, with the gas storage chamber positioned inside the bubble's volume. This nested arrangement allows the opening mechanism to be integrated into the existing package structure without adding external components, minimizing overall complexity while enabling rapid opening
Solution Approach 2:
The bubble structure serves multiple functions: it acts as the gas containment chamber, the expansion medium for breaching the seal, and the structural element that transfers force to separate the laminated layers. This multi-functionality reduces the need for separate components, offsetting the added complexity of the detonator mechanism
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bursting detonator enables rapid, energetic, and consistent package opening by transforming external mechanical energy into internal compression energy, ensuring a uniform rupture threshold and sound upon bursting, facilitating easy access to the sealed interior while accommodating multiple detonators and additional items.
Implementation Method 1
As the user presses on the bubble and detonator therein, compression energy builds in the bursting fluid. The external mechanical energy provided by the user, is transformed into internal compression energy.
Implementation Method 2
The bulk of this accumulated energy is instantaneously transferred at burst into the breaching bubble causing the bubble to expand and breech. The slow energy introduction by the user over the entire period of pressing, is released in an instant as an intense pressure pulse.
Implementation Method 3
Pressure on the bursting fluid within the detonator causes the detonator wall to rupture, initiating the breaching of the bubble. The rupture communicates the high fluid pressure within the bursting detonator into the bubble.

AI summary
Breaching access structure 10S provides easy access to sealed interior 10I containing contents 10C. Access region 12A proximate edge 12E of package 10, provides entrance into the interior and access to the contents. Band seal 14 formed by upper lamina 14U and lower lamina 14L extends along the access region, enclosing breaching bubble 16. The band seal has inner seal portion 14I between the bubble and the interior, and outer seal portion 14O between the bubble and edge 12E of the package. The bubble is expandable to open the package in response to bursting detonator 18. The detonator is burst by external pressure applied by a user. Opposed pair of peel flaps, upper flap 16U and lower flap 16L, are formed by the opposed laminae of the outer seal along the edge breach as the bubble breaches. These small initial flaps are grasped by the user and manually peeled apart to initiate opening the band seal.
