Safety Load Hook Visual Deformation Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current safety load hooks require time-consuming and device-dependent measurements to inspect deformation, making recurring inspections inefficient and prone to errors.
Innovation Solution
Incorporating markings on the upper and lower parts of the safety load hook that align visually when the hook mouth widens by a predefined amount, allowing for immediate visual inspection of deformation without the need for measuring devices or computational efforts.

Engineering Contradiction Analysis
1Measurement precision
If traditional measurement methods are used to inspect hook mouth deformation, then measurement precision can be ensured, but inspection time and device complexity increase
Solution Approach 1:
Reference markings are pre-applied to the hook body at specific positions. These markings serve as predetermined reference points that eliminate the need for measurements during inspection. The markings are positioned such that their relative displacement directly indicates the degree of hook mouth deformation, allowing inspectors to visually assess deformation without performing any measurements.
Solution Approach 2:
The invention creates a visual copy or representation of the deformation state through the relative positions of markings on different hook components. When the hook mouth deforms, the markings on the upper and lower parts of the hook shift relative to each other, creating a visual indicator that copies the deformation information in an easily observable form.
2Measurement precision
If traditional measurement methods are used to inspect hook mouth deformation, then accurate deformation detection is achieved, but device complexity and operational difficulty increase
Solution Approach 1:
The hook structure itself provides the measurement function through its markings. The relative positions of markings on different components serve as self-indicating features that show the deformation state without requiring external measuring devices or complex procedures. The structure informs its own status through the visual relationship between markings.
Solution Approach 2:
The invention uses visual contrast through markings (which may differ in color, pattern, or reflectivity) to indicate deformation. When the hook mouth deforms, the relative positions of these visually distinct markings change, providing an immediate visual signal of the deformation state that is easy to detect without specialized equipment.
3Productivity
If reference markings are applied to indicate deformation, then inspection speed improves, but manufacturing complexity increases
Solution Approach 1:
The reference marking system is divided into multiple segments applied to different components of the hook (upper part, lower part, and hook mouth). Each marking is applied to a specific component, and their relative positions across segments indicate deformation. This segmentation allows markings to be applied during normal manufacturing processes on individual components rather than requiring complex post-manufacturing application.

AI summary
A safety load hook with a lower part defining a curved hook mouth with a hook opening of a predefined nominal width. An upper part is attached to the lower part and is pivotable into an open position for insertion or removal of a load, and into a closed position blocking insertion of a load or removal of a load. A marking is on each of the end regions of the upper part and lower part which face one another in the closed state. When closed, and when a size of the hook opening corresponds to the nominal width, the lower part marking is offset from the upper part marking. The offset distance is chosen such that when there is a predefined maximum widening of the hook mouth in relation to the predefined nominal width thereof, both markings are located directly side by side in the closed state.
