Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pull-off construction suspensions for sidewalk and surface pavers face issues with torsional loads and uneven surface creation due to rigid pivot points, leading to broken components and unclean surfaces, especially when dealing with uneven terrain or maximum weight conditions.
Innovation Solution
A suspension system comprising spaced tension arms connected by a rotatable connecting profile with a centrally arranged holding element, allowing for adjustable movement and reduced stress, featuring a displaceable bearing profile and a tubular profile part for radial movement, enabling improved stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a fixed 2-point suspension with rigid pivot points is used, then the screed construction is stable and easy to control, but enormous torsional stress is placed on the screed drawbars leading to breakage
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed rigid pivot points with a dynamic suspension system comprising tension arms and a connecting profile that can rotate and move. The holding element with first and second holding parts allows the connecting profile to rotate, enabling the suspension to adapt to terrain variations and reduce torsional stress on the screed drawbars while maintaining stability.
2Ease of manufacture
If a fixed 2-point suspension with rigid pivot points is used, then the structure is simple and easy to manufacture, but improperly leveled surfaces with steps or transverse lines are created
Solution Approach 1:
The dynamic suspension system with rotatable connecting profile and movable holding element allows the screed construction to automatically adapt to uneven terrain, eliminating the need for complex adjustment mechanisms while achieving properly leveled surfaces without steps or transverse lines.
Solution Approach 2:
The patent applies parameter changes by allowing the connecting profile to rotate and the holding element to move between different positions, enabling the suspension to adjust its geometric parameters in response to terrain variations, thereby maintaining surface leveling precision without complicating the manufacturing process.
3Device complexity
If a fixed 2-point suspension is used, then the device complexity is low, but repeated leveling is required due to uneven surfaces
Solution Approach 1:
The dynamic suspension system with rotatable connecting profile and movable holding element automatically compensates for terrain unevenness during operation, eliminating the need for repeated leveling operations and time-consuming adjustments while maintaining relatively simple device complexity.
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 solution significantly reduces the risk of component failure, enhances working speed and precision, and ensures cleaner surface finishes by accommodating uneven terrain without the need for repeated surface adjustments.
Implementation Method 1
the connecting profile (12) can be set in a rotary movement, wherein the holding element (120) comprises a first holding part (1200) arranged on the connecting profile (12) and a second holding part (1202) which is connected in an articulated manner to the first holding part (1200) via a joint (1201)
Implementation Method 2
the connecting profile (12) and/or the tension arms (10) is/are displaceably mounted in a bearing profile (11) in a plane E aligned orthogonally to the connecting profile axis VA
Implementation Method 3
the connecting profile (12) can move like a pendulum and can advantageously move radially freely and without tension in the tubular profile part (1203) (lubrication via grease nipple)
