Movable Tilt Axis Anchor Point Prevents Sudden Turnover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor points fail to orient themselves smoothly in load situations where the force applied passes through the axis of rotation, leading to sudden turnover and potential fracturing due to inadequate lever arm strength.
Innovation Solution
The tilt axis of the anchor point is made movable relative to the base, allowing it to follow the force direction and preventing sudden turnover by enabling asymmetrical load distribution, with features like bearing pins and mechanical constraining guides for controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tilt axis is fixed relative to the base, then the structure is simple and stable, but the retainer bracket cannot smoothly reorient in certain load situations, leading to sudden turnover and potential failure
Solution Approach 1:
The tilt axis is made movable relative to the base through bearing pins supported in reception means, allowing the axis to dynamically adjust its position. This enables the retainer bracket to gradually reorient under load by translating the tilt axis along a constrained path, preventing sudden turnover while maintaining structural integrity.
2Ease of operation
If the bearing pin is constrained in a predetermined direction, then the movability of the tilt axis is controlled and predictable, but the range of motion is limited
Solution Approach 1:
A mechanical constraining guide acts as an intermediary between the bearing pin and the base, providing controlled movement in predetermined directions. The guide allows the tilt axis to move along a specific path (linear, curved, or oblique) while preventing uncontrolled motion, thus balancing controllability with adaptability.

AI summary
An anchor point (1) for e.g. lifting and/or lashing down an object (2) includes a base (4), which is configured for fixing to the object (2) such that it is rotatable about an axis of rotation (7). The anchor point (1) also includes a retainer bracket (3) held on two bearing points (5) on the base (4) such that it is tiltable about a tilt axis (11) relative to the base (4). In order to prevent the retainer bracket (3) from getting stuck when a force is applied thereto, which may lead to a sudden and jerky turnover of the retainer bracket or even to fracturing of the anchor point (1) and crashing of the load, the tilt axis (11) is movable relative to the base (4). Preferably, a motion link (25), for example, is provided on at least one bearing point (5).
