Magnetic Clamp Locking Mechanism for Orientation-Independent Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping devices for securing objects like laser levels to work pieces often lack a reliable and easy-to-use locking mechanism that functions effectively in various orientations, leading to instability and difficulty in secure attachment.
Innovation Solution
A clamp with a locking mechanism featuring a shaft, movable jaw, and a locking component that can actuate between locked and unlocked positions, utilizing a biasing element such as a magnet to maintain the shaft's position, and a securing component that rotates circumferentially to secure or release the clamp, allowing for easy orientation-independent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clamping mechanism is used, then the clamp can attach to work pieces, but the locking mechanism is unreliable and difficult to use in various orientations
Solution Approach 1:
The biasing element automatically maintains the shaft in a predetermined position without requiring user intervention. The magnetic biasing force continuously acts on the shaft to keep it engaged with the locking component, making the system self-regulating and eliminating the need for manual positioning or adjustment by the user.
Solution Approach 2:
The biasing element creates a magnetic field that provides uniform holding force regardless of the clamp's orientation. This ensures the locking mechanism functions reliably in any position (vertical, horizontal, tilted) by maintaining constant magnetic attraction between the shaft and locking component, effectively creating an equipotential locking state in all orientations.
2Reliability
If a locking mechanism with multiple components is implemented, then the shaft can be secured in position, but the device complexity increases
Solution Approach 1:
The biasing element acts as an intermediary between the shaft and locking component, providing continuous magnetic force to maintain engagement. This intermediary mechanism simplifies the overall design by replacing complex mechanical locking features (such as multiple springs, detents, or adjustment mechanisms) with a single magnetic field-based solution that achieves the same positioning stability.
Solution Approach 2:
The magnetic biasing element replaces traditional mechanical locking mechanisms (such as spring-loaded detents, threaded fasteners, or cam-based locks) with a magnetic field-based system. This substitution reduces the number of moving parts and mechanical interfaces while maintaining reliable shaft positioning, thereby reducing overall device complexity.
3Ease of operation
If the shaft is freely movable for adjustment, then the clamp can be positioned, but the shaft cannot remain stationary once positioned
Solution Approach 1:
The locking mechanism provides dynamic control of the shaft, allowing it to transition between two states: a movable state for positioning and a locked state for stabilization. The biasing element enables the shaft to be freely adjusted when not engaged, then automatically secures it in the predetermined position when the locking component engages, maintaining appropriate mobility or stability based on operational needs.
Solution Approach 2:
The biasing element pre-positions the shaft in a predetermined location before the locking component engages. This preliminary positioning ensures that when the clamp is released, the shaft is already in the correct position, and the locking component simply needs to engage to maintain that position, rather than requiring the shaft to be precisely positioned and then locked.

AI summary
A clamp release mechanism is provided. The clamp includes a body, a shaft slideably coupled to the body, a fixed jaw, and a moveable jaw coupled to the shaft. A locking component actuates between a locked position and an unlocked position. When in the locked position, the locking component biases the shaft to remain stationary with respect to the body. The clamp includes a securing component pivotally coupled to the locking component, and a biasing element that biases the securing components towards the shaft.
