Marker Installation Apparatus With Magazine And Push Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground marking systems are laborious and inefficient, particularly when inserting markers into compacted, stony, or frozen ground, as they often require manual effort and can be difficult due to increased resistance and reliance on friction, which can lead to physical strain and insertion challenges.
Innovation Solution
A marker system with a shaft comprising an insertion portion, a mast portion, and an engagement portion that resists further insertion, combined with a magazine assembly and push assembly for easy and uniform marker placement, reducing the need for manual force and minimizing resistance by avoiding friction reliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If markers are inserted manually into the ground, then the operation can be performed without mechanical assistance, but the repeated bending down is physically taxing on the person performing the marking operation
Solution Approach 1:
The marker installation apparatus is designed to be self-loading, where the magazine automatically feeds markers to the insertion position without requiring manual reloading for each marker. The apparatus performs its own marker delivery function, eliminating the need for continuous manual intervention and reducing physical strain on the operator.
Solution Approach 2:
The patent replaces the manual mechanical insertion process with an automated mechanical system. The push assembly and magazine work together to automatically position and insert markers into the ground, substituting the operator's manual bending and insertion actions with a mechanical automation system that reduces physical strain.
2Strength
If devices increase the cross sectional profile of the marker portion being inserted, then they provide structural support, but they cause more resistance due to the larger profile making insertion difficult in compacted, stony, or frozen ground
Solution Approach 1:
The marker shaft is segmented into distinct functional portions: an insertion portion with a first cross-sectional profile optimized for minimal ground resistance, an engagement portion for mechanical engagement, and a mast portion for above-ground visibility. This segmentation allows each portion to have optimized dimensions for its specific function, enabling easy insertion while maintaining overall structural integrity.
Solution Approach 2:
Different portions of the marker shaft have different cross-sectional profiles tailored to their specific functions. The insertion portion has a smaller, optimized profile for easy ground penetration, while other portions have profiles suited for their respective functions. This local differentiation of properties allows the marker to be easily inserted without compromising the rigidity needed for other functions.
3Force
If devices rely on friction between the device and marker to move the marker, then they can transfer force, but this approach is less effective when the ground is compacted, stony, or frozen
Solution Approach 1:
The push assembly acts as an intermediary mechanical element that directly engages the marker's engagement portion. Instead of relying on friction between the device and marker, the push assembly provides direct mechanical contact and force transmission through the engagement portion, which is specifically designed to interface with the push assembly's pushing member for reliable force transfer.
4Productivity
If devices require continual reloading of the marker, then they can accommodate multiple markers, but this requires continual reloading of the device which reduces efficiency
Solution Approach 1:
The magazine is pre-loaded with multiple markers before the installation process begins. This preliminary loading action eliminates the need for continual reloading during marker installation, allowing the operator to continuously install markers without interruption. The magazine serves as a pre-stored supply system that maintains installation momentum and productivity.
Solution Approach 2:
The magazine assembly is designed to automatically feed markers to the insertion position continuously as markers are installed. This creates a continuous flow of marker delivery without interruption or manual reloading, maintaining the useful action of marker installation without breaks and maximizing productivity throughout the marking operation.

AI summary
A marker installation system comprises a marker comprising a shaft having a bottom end and a top end, and including an insertion portion, a mast portion, and an engagement portion located between the insertion portion and the mast portion. The engagement portion is configured to resist further insertion of the shaft into the ground beyond the insertion portion. The system includes a marker installation apparatus including a magazine assembly defining a magazine space in which the marker is positioned. The magazine space has a push position in the magazine space for receiving the marker. The apparatus includes a push assembly mounted on the magazine assembly to engage the engagement portion of the marker when the marker is located in the push position. The push assembly pushes the marker from the push position of the magazine assembly when the push assembly is actuated.
