Scaffold Bracket Engagement Hook Anti-Rotation Design
Solution Overview
Problem
Existing scaffolding mounting brackets lack sufficient protection against rotation and accidental disengagement, posing safety risks during assembly and use, as they can be easily hung incorrectly and are prone to twisting.
Innovation Solution
A mounting bracket with a cantilever arm and a holding device featuring an engagement hook that securely attaches to a vertical frame, including a stop element to prevent rotation, ensuring a tamper-proof and visually verifiable connection, designed for easy assembly and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple bracket design is used, then ease of manufacture is improved, but reliability deteriorates due to insufficient protection against rotation and accidental disengagement
Solution Approach 1:
The retaining device is segmented into distinct functional components: an end element with a first opening for receiving the connecting element, and an engagement hook with a second opening that encompasses more than 180° of the connecting element. This segmentation allows each component to perform its specific function independently while maintaining overall simplicity and reliability.
Solution Approach 2:
The engagement hook is designed with asymmetric geometry where it encompasses more than 180° (preferably more than 270°) of the connecting element's circumference. This asymmetric design prevents rotation and accidental disengagement while maintaining ease of manufacture from a single piece of material.
2Reliability
If additional safety features are added to prevent rotation and disengagement, then reliability is improved, but device complexity increases
Solution Approach 1:
The end element and engagement hook are merged into a single integrated retaining device that can be manufactured as one piece. This combining of functions reduces device complexity while maintaining reliability through the coordinated action of the first opening (for receiving) and the second opening (for preventing rotation and disengagement).

AI summary
The present invention relates to a mounting bracket (100) for scaffold boards for detachable connection to a connecting element of a vertical frame. The mounting bracket (100) comprises a projection arm (1) with a longitudinal axis (L) for receiving a scaffold board and a holding device (2) for attaching the mounting bracket (100) to a connecting element. The holding device (2) has a terminal element (21) and an engagement hook (22). In one end position of the mounting bracket (100), the engagement hook (22) is located at the top of the holding device (2). In this end position, the engagement hook (22) engages the connecting element perpendicular to the longitudinal axis (L) by more than 180 degrees. The engagement hook (22) has a downwardly directed engagement end (221).
