Fastener Driver Rack-and-Lock Mechanism for Clog Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drivers do not effectively handle the issue of fastener clogging in the ejection part, which can hinder operation.
Innovation Solution
The driver incorporates a rack and rotary component that engages with a rack, allowing the impactor to move from a second position to a first position during rotation, and includes an engagement member that disengages after reaching the first position, preventing operation when the fastener is clogged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver operates continuously without detection mechanism, then productivity is maintained, but fastener clogging causes operational failures and downtime
Solution Approach 1:
The detection mechanism proactively identifies fastener clogging in the ejection part before it causes complete operational failure. The rotary component monitors the ejection process and detects abnormalities in advance, allowing the system to alert the operator or take corrective action before productivity is significantly impacted.
Solution Approach 2:
The rotary component acts as an intermediary detection mechanism between the fastener ejection process and the control system. It monitors the ejection part for clogged fasteners and translates this physical state into detectable signals that can trigger alerts or shutdowns, preventing complete system failure.
2Productivity
If the impactor moves rapidly through the full range, then productivity increases, but fastener clogging causes impactor damage and operational interruptions
Solution Approach 1:
The detection mechanism provides real-time feedback about fastener clogging conditions to the control system. When clogging is detected, the system can adjust the impactor's operation or alert the operator, preventing damage from forced operation and ensuring continuous reliable productivity.
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
This design prevents operation when a fastener is clogged in the ejection part, ensuring smooth operation and facilitating easy removal of clogged fasteners.
Implementation Method 1
a rack provided to the impactor, the driver has a rotary component engaging with the rack and moving the impactor from the second position to the first position
Implementation Method 2
the rotary component is released from engaging with the rack after the impactor moves from the second position to the first position, and moves from the first position to the second position, and the engagement member is engageable with the rack when the impactor stops before reaching the second position from the first position

AI summary
A driver including: an ejection part to which a fastener is supplied; a driver blade which moves from a first position toward a second position and drives the fastener into a driven member; and a rack provided to the driver blade. The driver further includes: a rotary component engaging with the rack and moving the driver blade from the second position to the first position; and a lock plate engaging with the rack. The driver blade moves from the second position to the first position while the rotary component rotates once, the rotary component is released from engaging with the rack after the driver blade moves from the second position to the first position, and moves from the first position to the second position, and the lock plate is engageable with the rack when the driver blade stops before reaching the second position from the first position.
