Drill Attachment Trigger Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drilling holes in concrete with a hammer drill is physically exhausting for users due to the need to maintain the drill in proper orientation for extended periods, requiring a solution that allows for actuation without direct user operation.
Innovation Solution
A drill attachment with a bifurcated frame and a handle-activated trigger mechanism that engages and disengages the drill trigger through a cable system, enabling remote operation of the drill apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user directly operates the hammer drill by sitting or kneeling for long periods, then the drill can be maintained in proper orientation during operation, but the user experiences physical exhaustion and discomfort
Solution Approach 1:
The patent introduces a remote control device as an intermediary between the user and the hammer drill. The remote control contains a trigger mechanism that transmits signals to the drill via radio frequency, allowing the user to operate the drill without physically holding or positioning it. This mediator eliminates the need for the user to sit or kneel for extended periods while maintaining proper drill orientation.
Solution Approach 2:
The patent replaces the direct mechanical interaction between the user and the drill with an electromagnetic signal-based control system. Instead of the user manually manipulating the drill trigger and body, the system uses wireless communication to transmit actuation commands from the remote control to the drill, substituting mechanical operation with electromagnetic actuation.
2Productivity
If the user directly handles the hammer drill, then the drill can be controlled for drilling operations, but the user must maintain proper orientation for extended periods which causes discomfort
Solution Approach 1:
The remote control device serves as a mediator that allows the user to control the drill from a distance. The user can remain in a comfortable position (sitting or kneeling) while the remote control transmits signals to activate the drill, eliminating the need to maintain proper orientation manually during extended drilling operations.
Solution Approach 2:
The system enables the drill to be operated autonomously based on remote signals. Once activated through the remote control, the drill can continue drilling operations without requiring continuous manual adjustment or user presence in the drilling position, allowing the user to perform other tasks or remain in comfortable positions.
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 the actuation of a drill apparatus without direct user operation, reducing physical strain and improving comfort during prolonged drilling tasks.
Implementation Method 1
a trigger cable extending between the handle and the trigger actuator
Implementation Method 2
a trigger cable extending between the handle and the trigger actuator
Implementation Method 3
the trigger actuator having a rocking arm adapted to pivot relative to the first shaft when actuated by the handle through the trigger cable
Data Source
AI summary
A drill attachment for engagement and actuation of a drill apparatus having a bifurcated frame defining a first shaft and a second shaft operatively engaged to the drill apparatus at first and second engagement points is disclosed. A handle is pivotally engaged to the first shaft and is operatively coupled to a trigger actuator located along the first shaft through a trigger cable operatively engaged to a trigger actuator the distal end of the first shaft that permits remote actuation of the drill apparatus. The trigger actuator includes a pivotable rocking arm having an actuator pad in selective engagement with the drill trigger such that actuation of the handle by the user pivots the rocking arm in a manner that causes the actuator pad to engage or disengage the drill trigger when operating the drill apparatus. A knee pad may extend from the first shaft to provide the user a contact surface for applying pressure in a lateral direction in order to abut the drill apparatus to the drill surface.
