Router Motor Unit Release Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current routers lack a reliable mechanism to securely attach the motor unit to the base unit, leading to potential misalignment and imprecise cuts or grooves during operations.
Innovation Solution
A combination router design featuring a depth adjustment latch and a release latch system that secures the motor unit to the base unit along the motor axis, allowing for precise positioning and secure attachment, preventing accidental detachment during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single fastener is used to secure the motor unit to the carriage, then the device complexity is reduced, but the reliability of securing the motor unit is insufficient
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated latch mechanism. The latch member simultaneously performs depth adjustment, positioning, and securing functions that would otherwise require separate mechanisms, thereby improving reliability without proportionally increasing complexity.
Solution Approach 2:
The latch member is designed as a multi-functional component that can adjust the depth of the motor unit, secure it in position, and prevent accidental detachment all through a single mechanism. This universal component handles multiple tasks that would traditionally require separate fasteners and adjustment devices.
2Ease of operation
If the motor unit is made easily removable from the base unit, then the ease of operation is improved, but the reliability of preventing accidental detachment deteriorates
Solution Approach 1:
The latch mechanism transitions between locked and unlocked states dynamically. During normal operation, the latch securely holds the motor unit in place. When the release member is actuated, the latch quickly transitions to an unlocked state, allowing easy removal. This dynamic behavior provides both security during use and ease of removal when needed.
Solution Approach 2:
The release member acts as an intermediary control element between the user and the latch mechanism. By pressing the release member, the user indirectly actuates the latch to unlock it, providing a controlled and deliberate method for removal that prevents accidental detachment while maintaining ease of operation when intentionally released.
3Ease of operation
If the latch mechanism allows movement along the motor axis, then the ease of operation for depth adjustment is improved, but the reliability of maintaining precise position deteriorates
Solution Approach 1:
The latch mechanism is designed to engage with the motor unit at predetermined depth positions along the motor axis. The user can adjust the depth by moving the motor unit along the axis, and the latch will engage at pre-determined positions, providing both ease of adjustment and precise positioning. The preliminary engagement points ensure accurate reproduction of depth settings.

AI summary
A routing machine comprises a base unit and a motor unit, which is releasably connected to the base unit. The motor unit defines a motor axis is configured for insertion into the base unit substantially in the direction of the motor axis. A depth adjustment latch is provided on the base unit. A release latch is provided on the base unit. The release latch is moveable between a first position and a second position. The release latch is configured to provide a positive stop for the motor unit when the release latch is in the first position, such that the motor unit is blocked from release from the base unit while allowing the motor unit to move along the motor axis. The motor unit is free to release from the base unit when the release latch is in the second position.
