Problem
Existing rock drills are cumbersome, unsafe, and require heavy machinery for transport and setup, posing challenges in precision and operator safety due to manual guidance and potential drill bit sticking during operation.
Innovation Solution
A compact, ergonomic rock drill chassis with a vertical frame member, drill guide sleeve, and remote control unit, allowing single-operator transport and setup, featuring anti-vibration and automatic operation to enhance safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rock drill components are fully assembled onto the chassis, then the structural integrity and stability are improved, but the overall weight increases to 300 or more pounds requiring heavy machinery for transport
Solution Approach 1:
The chassis is divided into modular components including the vertical frame member, wheel support member, wheel and bearing assembly, and drill guide assembly that can be separated for easier transport and reassembled at the worksite, reducing the need for heavy machinery while maintaining structural integrity when assembled
2Device complexity
If the rock drill is manually guided, then the device complexity is reduced, but the precision of hole placement deteriorates due to operator fatigue
Solution Approach 1:
A drill guide sleeve attached to the vertical frame member serves as an intermediary component that guides the drill bit along a predetermined path, ensuring precise hole placement while maintaining relatively simple device complexity through a straightforward mechanical guidance structure
3Productivity
If the drill bit becomes stuck or operator becomes incapacitated, then the drilling operation continues, but safety deteriorates creating dangerous situations
Solution Approach 1:
The remote control unit provides feedback-based operation where the operator can monitor drilling conditions and immediately stop or reverse the drill feed mechanism if abnormalities such as stuck drill bits are detected, preventing dangerous situations while maintaining operational efficiency through responsive control
4Ease of operation
If heavy machinery is used for loading and unloading, then the ease of operation is improved, but the device complexity and cost increase
Solution Approach 1:
The chassis incorporates a wheel support member with a wheel and bearing assembly that enables dynamic movement and maneuverability, allowing the chassis to be easily transported and positioned by hand without requiring heavy machinery for loading and unloading operations
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
Enables safe, precise, and efficient drilling with reduced weight and manual effort, minimizing vibration exposure and facilitating easy maneuverability without heavy machinery.
Implementation Method 1
The rock drill is attached to a feed mechanism that, when activated, will move the rock drill towards the drilling target and provide the necessary force to push the rotating drill bit into the material being drilled
Implementation Method 2
a wheel support member offset from the vertical frame member, and a wheel and bearing assembly supported on the wheel support member

AI summary
A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The system includes a remote control unit that is pneumatically coupled to the system and may be selectively detached from the utility chassis so that the operator may control the system via the remote control unit from afar. The utility chassis has a lightweight vertical frame member with an off-set wheel base that allows the system to maintain its balance and maintain engagement with the ground when while being operated remotely and without being manually supported.
