Hinged Jaw Tile Leveller Knob for Rapid Threaded Rod Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tile-laying devices, such as levellers, require lengthy and complex operations to attach and detach the knob from the threaded rod, making the process inefficient for aligning and laying tiles.
Innovation Solution
A knob with a pair of hinged jaws that form a threaded duct to engage with the strap's threaded rod, allowing for simple and rapid attachment and detachment without screwing, utilizing a latch mechanism for secure clamping and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a threaded rod with a knob is used to align tiles, then the alignment precision is improved, but the attachment and detachment operations become lengthy and complex
Solution Approach 1:
The knob is divided into two semi-cylindrical jaws that can open and close around the threaded rod. This segmentation allows the jaws to be quickly opened for attachment and closed for secure engagement, eliminating the need for lengthy screwing operations while maintaining precise alignment capability through the threaded duct formed by the jaws.
Solution Approach 2:
The jaws are made movable relative to each other through a hinge connection, allowing dynamic opening and closing actions. This dynamic mechanism enables rapid attachment by simply closing the jaws around the threaded rod and rapid detachment by opening the jaws, significantly reducing operation time while preserving alignment precision through the threaded engagement.
2Manufacturing precision
If a threaded rod with a knob is used to align tiles, then the alignment precision is improved, but the operational complexity increases
Solution Approach 1:
The knob is segmented into two jaws that independently engage with the threaded rod. This segmentation simplifies the engagement process to a single closing motion rather than rotational screwing, making the operation simpler while maintaining the precision alignment function through the threaded duct.
Solution Approach 2:
The hinged jaws provide dynamic movement capability, allowing the operator to simply open and close the jaws for attachment and detachment. This dynamic mechanism transforms complex rotational screwing operations into simple linear closing motions, greatly improving ease of operation while preserving alignment precision.
3Reliability
If traditional screwing operation is used to attach the knob, then secure connection is achieved, but the process is not practical for rapid tile laying
Solution Approach 1:
The segmented jaw structure allows the connection to be secured by simply closing the jaws around the threaded rod, eliminating the time-consuming screwing process. The threaded duct formed by the jaws ensures secure engagement while the segmented design enables rapid opening for detachment, significantly improving tile laying productivity without compromising connection reliability.
Solution Approach 2:
The dynamic hinged jaw mechanism allows rapid closing for secure attachment and rapid opening for detachment. This dynamic action replaces the slow rotational screwing process with quick linear motions, greatly increasing tile laying speed while the threaded engagement within the jaws maintains reliable and secure connection.
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 significantly reduces tile-laying time by enabling quick and practical alignment of tiles, as the knob can be fastened and released in a single rotation, streamlining the process.
