Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for holding measurement objects in a reference position often lack precision and require significant effort due to transverse components that impair the accuracy of the clamping position.
Innovation Solution
A clamping device that partially surrounds the carrier head with a fork part, featuring a lockable slide for linear adjustment parallel to the carrier head's feed axis, allowing precise alignment without transverse displacement, and includes a pivoting mechanism and a screw system for secure clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional clamping device with toggle lever is used, then the measurement object can be clamped, but transverse components displace the measurement object and impair clamping position accuracy
Solution Approach 1:
The clamping device is segmented into a fork part that surrounds the carrier head and a slide mechanism that moves independently along the feed axis. This segmentation allows the clamping force to be applied purely in the axial direction without transverse displacement components, resolving the contradiction between clamping effectiveness and position accuracy.
Solution Approach 2:
A slide mechanism acts as an intermediary between the clamping element and the carrier head. The slide moves linearly along the feed axis and transfers clamping force without introducing transverse components, thereby maintaining measurement object position accuracy while enabling effective clamping.
2Manufacturing precision
If the clamping element position is adjusted linearly without slide mechanism, then alignment precision improves, but transverse displacement occurs that impairs accuracy
Solution Approach 1:
The slide mechanism introduces a controlled linear movement dimension along the feed axis, separating the alignment function from the clamping function. This dimensional separation allows precise alignment through axial movement without generating harmful transverse displacement components that would compromise measurement accuracy.
3Manufacturing precision
If a complex adjustment mechanism is used to eliminate transverse components, then clamping position accuracy improves, but device complexity increases
Solution Approach 1:
The fork part is designed with a specific geometric configuration where the clamping surfaces are oriented perpendicular to the feed axis. This local geometric quality ensures that clamping force is applied purely axially without transverse components, achieving high position accuracy through simple local design rather than complex overall structure.
Solution Approach 2:
The slide mechanism automatically maintains linear movement along the feed axis through its guide structure, self-regulating to prevent transverse displacement without requiring additional complex control mechanisms. The design inherently eliminates the problematic transverse components through its own geometric constraints.
