Portable Explosive Detection Kit With Triple-Latch Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing explosives detection field test kits (ETKs) are difficult for occasional or untrained users to operate effectively, especially in high-stress situations, due to complex instructions, lack of training, and potential for kit components to be misplaced or misunderstood, leading to potential testing failures.
Innovation Solution
A portable ETK with a rugged design featuring a triple-latch system, permanently attached instructions, color-coded components, and a contoured test paper pocket to prevent components from falling out, ensuring easy operation and accurate results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the test kit uses complex instructions and multiple components, then the detection capability is improved, but the ease of operation deteriorates for untrained users
Solution Approach 1:
The test kit is divided into clearly defined components (drip tubes, test papers, swabs, instructions) with dedicated storage compartments. Each component has a specific function and is easily identifiable, allowing untrained users to understand and operate the kit without being overwhelmed by complexity.
Solution Approach 2:
The patent introduces an intermediary instruction card that mediates between the complex testing procedures and the user. The card provides step-by-step visual instructions with color coding that simplifies the operation process, bridging the gap between sophisticated detection capabilities and user-friendly operation.
2Volume of moving object
If the test kit components are stored in a compact housing, then the portability is improved, but the risk of component misplacement increases
Solution Approach 1:
The test kit employs a nested structure where drip tubes, test papers, and other components are stored within compartments inside the housing. The instruction card is nested within the housing and can be removed for reference. This nesting maintains compactness while preventing component misplacement through dedicated storage spaces.
Solution Approach 2:
The kit is pre-assembled with all components in their correct positions within the housing before deployment. The instruction card is pre-positioned and permanently attached, providing immediate guidance without requiring users to search for or organize components themselves.
3Ease of operation
If the instructions are permanently attached to the housing, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The instruction card is permanently attached to the inside of the housing lid, merging the instructional information with the physical structure of the kit. This integration ensures instructions are always accessible during use without adding separate components or increasing operational complexity.
Solution Approach 2:
The permanently attached instruction card enables the test kit to be self-instructing. Users can immediately access operational guidance without needing external manuals or training, allowing the kit to serve itself by providing all necessary information within its own structure.
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 ETK is designed to be user-friendly and reliable, preventing accidental opening and ensuring accurate testing results by keeping instructions accessible and components organized, even for untrained users in stressful conditions.
Implementation Method 1
a first hook and loop fastener and a mating second hook and loop fastener. The first hook and loop fastener is disposed on an inner surface of the latch lever and the second hook and loop fastener is disposed on a mating surface of the bottom cover, and the first and second hook and loop fasteners engage when the latch lever is in a closed position
Implementation Method 2
a stop rib operatively associated with the latch lever and configured to engage the underside of the latch face when the latch lever is in a closed position
Implementation Method 3
The top cover and bottom cover are joined by a hinge along the respective hinge sides thereof forming a housing having an open position wherein the latch sides of the top cover and bottom cover are separated, and a closed position wherein the latch sides of the top cover and bottom cover are joined
