Spring-Loaded Piercing Tool for Reliable Sealed Packaging Breakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for opening sealed packaging are unreliable, requiring significant manual effort, prone to liquid splashing, and pose safety risks, especially for individuals with less strength, and often result in time-consuming and labor-intensive operations.
Innovation Solution
A piercing tool with a body, barrel, and elastic element, where the piercing member moves into the barrel to deform elastically, restricted by a limiting structure, allowing quick piercing and stable operation, and includes a hollow structure for fast liquid discharge with pre-set air passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional piercing tools are used on curved or metal packaging, then the packaging can be broken open, but the tools may slip during cutting causing safety risks
Solution Approach 1:
The piercing tool is segmented into distinct functional components: a stable base body for positioning, a barrel for guiding the piercing member, and a separately actuated piercing component with elastic element. This segmentation allows each part to perform its specific function optimally - the base provides stability, the barrel provides guidance, and the piercing component provides the piercing action, collectively preventing slipping
Solution Approach 2:
The elastic element is pre-loaded in a compressed state before use, storing elastic potential energy. When released, this pre-stored energy drives the piercing member forward automatically, eliminating the need for manual pushing force that could cause slipping. The preliminary positioning of the piercing member at the barrel opening also prepares the tool for immediate action
2Object-affected harmful factors
If insufficient force is applied during piercing, then safety is maintained, but the packaging cannot be broken open
Solution Approach 1:
The hollow interior of the base body is designed to accommodate and contain the piercing action. When the piercing member penetrates the packaging, any liquid or debris is contained within this hollow space, preventing splashing outward. This cushioning space absorbs the impact and prevents harmful effects before they can occur
Solution Approach 2:
The barrel acts as an intermediary structure between the user's manual input and the piercing member. It guides and constrains the piercing component's movement, ensuring force is applied in the correct direction and magnitude. The barrel's confined space also prevents lateral movement that could cause splashing, while still allowing sufficient piercing force to be transmitted
3Reliability
If manual force is applied to pierce sealed packaging, then the packaging can be opened, but the operation becomes time-consuming and labor-intensive
Solution Approach 1:
The elastic element operates in a periodic cycle: it is compressed during the reset phase (storing energy) and then rapidly expands during the piercing phase (releasing energy). This periodic action converts gradual manual force application into a rapid, high-force piercing motion, dramatically reducing the time required for the piercing operation while maintaining reliability
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 tool ensures reliable and safe piercing of sealed containers, reduces liquid splashing, and facilitates rapid liquid flow by creating air passages, decreasing operational difficulty and intensity.
Implementation Method 1
The piercing member is capable of moving from the hollow interior of the body into the inside of the barrel to allow the elastic element to undergo elastic deformation

AI summary
A piercing tool for breaking sealed packaging includes a body for placing a target item. A barrel is provided on one sidewall of the body; a piercing component is slidably installed inside the barrel, and a piercing member arranged on the piercing component may enter the body along the barrel. An elastic element is connected to both the body and the piercing component. The piercing member is displaced from the body into the barrel to cause elastic deformation of the elastic element. A first limiting structure capable of resisting the elastic force is provided between the barrel and the piercing component to restrict the piercing member within the barrel. After the target item is fixed within the body, the piercing member springs back into the body along the barrel under the elastic force of the elastic element to quickly pierce the sealed packaging.
