Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel dividing systems face challenges in precisely and cost-effectively adjusting the vertical position of the scoring saw blade, requiring a robust and maintenance-free solution that can integrate with existing adjusting devices.
Innovation Solution
A mechanically robust adjustment device with a self-locking threaded sleeve and a stepper drive mechanism, utilizing a latching pawl and ratchet teeth with inclined flanks, along with a pneumatic or other drive principles, allows for precise and predictable adjustability of the scoring saw blade, reducing wear and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional adjusting device is used for the scoring saw blade, then the structure is simpler, but the adjustment precision and reliability are insufficient
Solution Approach 1:
The patent replaces conventional mechanical adjusting devices with a screw mechanism combined with a latching pawl and ratchet tooth system. The threaded sleeve converts rotational motion into precise linear displacement, while the latching mechanism maintains positional accuracy without requiring complex electronic controls or multiple adjustment components.
Solution Approach 2:
The latching pawl automatically engages with the ratchet teeth on the threaded sleeve to maintain the adjusted position without requiring additional locking mechanisms or complex control systems. The spring-loaded pawl self-activates upon rotation of the threaded sleeve, providing automatic position maintenance that simplifies the overall device structure while improving reliability.
2Measurement precision
If the threaded sleeve is made adjustable with fine pitch, then the adjustment precision improves, but the device size increases
Solution Approach 1:
The patent achieves precise adjustment by changing the thread pitch parameter of the threaded sleeve to a fine pitch configuration. This allows small linear displacements per rotation, enabling precise vertical positioning of the scoring saw blade without requiring multiple stages of adjustment or complex mechanisms that would increase device volume.
3Ease of operation
If the latching pawl is designed with inclined flank, then the maximum end position is defined without constraining forces, but the mechanism complexity increases
Solution Approach 1:
Instead of using a conventional flat-faced latching pawl that requires precise positioning and may create constraining forces, the patent inverts the approach by giving the pawl an inclined flank that actively defines the end position through its geometry. The inclined surface allows the pawl to naturally locate against the ratchet tooth, defining the maximum travel position without requiring additional positioning features or creating binding forces on the threaded sleeve.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise, cost-effective, and low-maintenance adjustment of the scoring saw blade's vertical position, ensuring reliable operation and compatibility with existing systems, while minimizing noise and wear.
Implementation Method 1
a threaded sleeve (74) which is coupled to a stop (70) or at the lower end of which the stop (70) is formed and with which the piston rod (66) can be locked in a vertically adjustable manner
Implementation Method 2
By selecting the thread pitch of the threaded sleeve accordingly, the threaded sleeve is self-locking
Implementation Method 3
a latching pawl (82a, 82b) which can be moved by the actuator (78a, 78b) essentially in a translatory and orthogonal manner to the vertical axis of rotation (72) and can be pivoted about an essentially vertical axis (80) and which has a latching tooth section (84)
Implementation Method 4
the latching tooth section (84) comprises a latching tooth (88a, 88b) in at least one of two vertical end regions (86a, 86b), the flank of which has a slope such that the latching pawl (82a, 82b) slips off when it hits the slope
Implementation Method 5
the locking pawl or the locking pawls are connected to a spring which acts or acts on the locking pawl(s) against the locking tooth section
Implementation Method 6
the adjusting device comprises a damping section which dips into a damping chamber of the stop shortly before the actuating element or the piston reaches the end position

AI summary
A panel dividing system comprises at least one saw blade and an adjusting device (60) for adjusting the vertical position of the saw blade. It is proposed that the adjusting device (60) comprises a lifting cylinder (62) having a piston (64) and a stop (70), settable by means of a remote-control setting device (68), for defining a preferably top end position of the piston (64).
