Core Drill Stand With Tool-Free Clamping and Vacuum Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drill stands do not provide a convenient and efficient way to operate core drills both when mounted on a stand and when carried independently by an operator, particularly in terms of battery power management and tool-free assembly/disassembly.
Innovation Solution
A drill stand system with a housing and battery pack that allows the core drill to be operated both when attached to and detached from the stand, featuring a tool-free clamping mechanism, collapsible design, and vacuum-based mounting for secure attachment to surfaces, enabling easy handling and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the core drill is designed to be operated both on a stand and handheld, then the versatility of the drill system is improved, but the device complexity increases due to the need for multiple mounting and carrying configurations
Solution Approach 1:
The drill stand base is designed to serve multiple functions: it provides a stable mounting platform when the drill is stationary, and transforms into a carrying handle when the drill needs to be moved or used handheld. This multi-functional design allows the same structural component to support both fixed and portable operational modes, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The transition mechanism allows the drill stand components to dynamically change configuration between extended (for stable mounting) and collapsed (for portable carrying) states. This dynamic adaptability enables the system to optimize its structural characteristics based on the operational mode required, maintaining simplicity in each state while achieving versatility across states.
2Ease of operation
If a tool-free clamping mechanism is implemented for quick assembly and disassembly, then the ease of operation is improved, but the reliability of the connection may worsen due to the absence of traditional fastening methods
Solution Approach 1:
The traditional mechanical fastening system (screws, bolts, and tools) is replaced with a spring-loaded clamping mechanism that uses elastic force and friction to secure the drill to the stand. This substitution maintains connection reliability through robust mechanical engagement while eliminating the need for tools, thus improving ease of operation without sacrificing connection stability.
Solution Approach 2:
The clamping mechanism is designed to be self-actuating through spring force, automatically securing the drill when mounted and releasing when disassembled. This self-service mechanism eliminates the need for external tools or complex fastening procedures, providing both ease of operation and sufficient reliability through the spring-loaded engagement design.
3Ease of operation
If the drill stand includes a collapsible design for easy transportation, then the ease of operation is improved, but the volume of the object increases when in extended configuration
Solution Approach 1:
The drill stand employs a collapsible design where the support arms and base structure can dynamically transition between extended (for stable operation) and collapsed (for compact storage and transport) configurations. This dynamic structure allows the stand to achieve its full functional volume only when needed, while minimizing volume during transportation, thus resolving the contradiction between operational stability and portability.
Solution Approach 2:
The collapsible design allows components of the drill stand to nest within each other when collapsed, with support arms and base elements fitting into one another to create a compact package. This nesting arrangement minimizes the overall volume during storage and transport while maintaining the full extended configuration when operational stability is required.
