Tilt-adjustable table top device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt-adjustable storage devices fail to ensure a robust bearing of teeth on the edge of the recess during unintentional impacts on the tabletop, leading to potential sliding issues.
Innovation Solution
A safety device featuring a U-leg with displaceable leg pieces and a support spring is integrated near the recess of the locking plate to secure the toothed rack's engagement with the edge, preventing unintentional sliding and providing protection against impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a toothed rack is engaged with the edge of the recess in the locking plate, then the storage panel can be tilted and locked at various angles, but the tooth may slide unintentionally when impacted against the tabletop
Solution Approach 1:
The U-leg safety device is positioned beforehand to cushion and prevent unintentional sliding of the toothed rack teeth from the recess edge. The U-leg acts as a protective barrier that engages before any harmful sliding can occur, ensuring the tooth remains securely positioned even during impacts or accidental forces on the tabletop.
2Reliability
If a safety device is added to protect the toothed rack engagement, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The safety device is implemented locally only where needed - the U-leg is positioned specifically near the recess in the locking plate to protect the toothed rack engagement. This localized approach provides the necessary reliability improvement without adding complexity to the entire device, as only a small portion of the system requires the protective feature.
3Stability of the object's composition
If the locking plate is arranged on the lower surface of the tabletop, then the structural integration is improved, but the accessibility for manual operation becomes more difficult
Solution Approach 1:
The U-leg safety device is nested within or integrated into the locking plate structure itself. The U-leg forms part of the locking plate assembly, with its legs extending through openings in the locking plate. This nesting approach maintains the structural integration of the locking plate into the tabletop while providing the safety function without requiring separate external components that would compromise accessibility.
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
Ensures secure engagement of the toothed rack's teeth with the recess edge, preventing accidental sliding and ensuring safety by using gravitational action and a locking mechanism that does not require additional springs, thus enhancing the device's stability and safety.
Implementation Method 1
a support spring is provided between a plate fixedly arranged in the region of one end of a leg piece and the web in order to support the base of the U-leg in the direction of the toothed rack
Implementation Method 2
A detachable fixing of the storage panel by hand is made possible in the device according to the invention by natural pivoting by gravitational action of the one or more toothed racks
