Portable Drill Press Attachment With Lever Base for Tight-Space Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling holes in metal requires significant energy and time, and existing drill press solutions are often bulky and difficult to maneuver in tight spaces, limiting control and efficiency.
Innovation Solution
A portable drill press attachment for handheld drills that utilizes leverage by hooking onto the metal and applying pressure through a sliding bar mechanism, eliminating the need for a handle to tighten the drill bit, allowing for easier and faster hole drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional drill press is used to drill holes in metal, then drilling stability and force application are improved, but the device becomes bulky and difficult to maneuver in tight spaces
Solution Approach 1:
The invention divides the drill press into two separate components: a handheld drill unit and a portable attachment. The attachment includes a base that hooks onto the workpiece and a mounting structure that secures the drill, allowing the drilling function to be segmented into manageable parts that can be maneuvered independently into tight spaces while maintaining stability during operation
Solution Approach 2:
The attachment incorporates a dynamic positioning system where the base can be hooked onto different locations of the workpiece and the drill angle can be adjusted. The mounting mechanism allows the drill to be securely attached at various orientations, providing adaptability and stability for different drilling positions and configurations
2Force
If a handle mechanism is added to tighten the drill bit against the metal, then drilling force and control are improved, but the device becomes more complex and larger
Solution Approach 1:
The attachment utilizes the user's hand holding the drill as the tightening mechanism. By gripping the drill handle, the operator's hand automatically applies the necessary clamping force to press the drill bit against the workpiece through the attachment structure, eliminating the need for a separate automated handle mechanism while maintaining effective drilling force
Solution Approach 2:
The attachment acts as an intermediary mechanical structure that translates the gripping force from the operator's hand into effective drilling pressure. The mounting bracket and base configuration serve as mechanical intermediaries that amplify and direct the manual gripping force onto the drill bit, providing controlled drilling force without complex mechanisms
3Ease of operation
If the drill press is made compact to fit in tight spots, then accessibility and portability are improved, but control and stability during drilling may be reduced
Solution Approach 1:
By separating the drill from the base attachment, the system allows the compact attachment to provide stability while the handheld drill provides control. The segmented design enables the small attachment to hook securely onto the workpiece in tight spaces, while the operator maintains full control through direct hand grip on the drill, achieving both accessibility and stability
Solution Approach 2:
The invention merges the functions of a traditional drill press (stability and force application) with a handheld drill (portability and control) into a single integrated system. The attachment combines the base that provides anchoring stability with the mounting structure that secures the drill, creating a unified tool that delivers both compactness for accessibility and sufficient control for stable drilling
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 stable and efficient drilling with reduced energy expenditure, as the attachment provides better control and can fit into confined areas due to its compact design and absence of a handle, facilitating quicker hole creation.
Implementation Method 1
Spring 6. Pushes on the locking wedge keeping it locked at all times.
Implementation Method 2
Locking wedge 4. This wedge stops the bar from sliding forward.
Implementation Method 3
Hinge 8. This allows the drill to be farther away from where the base is hooked on.

AI summary
This accessory, for a hand held drill, turns the drill into a portable drill press. To use this portable drill press, place the drill bit where you want it. Lean the drill forward until the base slides under the metal your drilling. The base is a lever and the drill and bit swings off it. The base holds the drill in place at a angle. When the drill is pulled straight, everything tightens up. The metal and the drill bit are pushed together with leverage. Turn the drill on and drill the hole by just holding the drill straight. This portable drill press is faster and easier to use, than drilling by hand.
