Solution Overview

Problem

Existing fastening systems for rod-shaped objects, such as masts or poles, are either non-adjustable once set or require complex installation due to large space requirements, making it difficult to achieve precise angular alignment and compact placement.

Innovation Solution

A sleeve with an adjusting device featuring a first and second adjustable holding device, where the second holding device is a rotatable holding disk, allowing for stepless adjustment of the rod-shaped object's position and angle relative to the sleeve, utilizing eccentric bores and recesses for secure fixation and easy rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a fastening system uses filling material particles to fix the rod-shaped object after alignment, then the object position is fixed, but the setting cannot be corrected and installation becomes awkward

Engineering Contradiction:
Improvefixed positionVSAvoidadjustability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent employs two adjustable holding devices with eccentric bore arrangements that enable dynamic adjustment of the rod-shaped object's position and angle. The first holding device adjusts position in a first plane while the second holding device adjusts position in a second plane, allowing stepless adjustment before final fixation. This dynamic adjustment mechanism resolves the contradiction by providing both adjustability during installation and stability after positioning.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If a fastening device uses eccentric bore arrangements for adjustment, then angular alignment is achieved, but installation space requirements increase significantly

Engineering Contradiction:
Improveangular alignmentVSAvoidinstallation space
Core Design Contradiction:
Manufacturing precisionVSVolume of stationary object

Solution Approach 1:

The patent places the two adjustable holding devices at different levels within the same sleeve structure. The first holding device is arranged in a first plane and the second holding device is arranged in a second plane, both within the sleeve's internal volume. This nested arrangement achieves precise angular alignment through eccentric bore adjustments while minimizing the overall installation space required, as both adjustment mechanisms are contained within the single sleeve rather than requiring separate components.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If a fastening device requires large axial space for adjustment mechanisms, then adjustment capability is provided, but installation becomes complicated requiring excessive force and earth displacement

Engineering Contradiction:
Improveadjustment capabilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transitions from a single-plane adjustment mechanism to a multi-plane arrangement by positioning the first holding device in a first plane and the second holding device in a second plane. This dimensional change allows both adjustment capabilities (position and angle) to be achieved within a compact axial space, simplifying installation by reducing the required excavation depth and force while maintaining full adjustability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An adjusting device for the alignment, particularly for the angular alignment, of a rod-shaped object, particularly a pole or a post, relative to a sleeve in which the rod-shaped object can be inserted at least partially, particularly relative to a ground sleeve and/or a ground dowel, comprises a first adjustable holding device, which can be used to adjust the position of the rod-shaped object relative to the sleeve in a first plane, and a second adjustable holding device, which can be used to adjust the position of the rod-shaped object relative to the sleeve in a second plane which differs from the first plane.
