Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-uplift systems for construction posts are complex and difficult to implement, requiring additional components like metal rods for preventing unintentional lifting.
Innovation Solution
A post design featuring a cylindrical upright with two offset cylinders and a tubular element with a stop mechanism, allowing for easy locking and rotation within a recess, facilitating quick and simple installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal rod articulated on the post is used as an anti-lifting system, then the post is effectively protected from unintentional lifting, but the system becomes complex and difficult to implement
Solution Approach 1:
The patent extracts the essential anti-lifting function from the complex articulated metal rod system and implements it through a simple rotation-locking mechanism. The tubular element with offset axis and stop means provides the necessary restraint without requiring additional articulated components, thereby maintaining reliability while reducing complexity
Solution Approach 2:
The post's own cylindrical structure with offset axes is utilized to create the locking mechanism. The tubular element rotates within the recess and locks automatically when its axis aligns with the recess axis, making the system self-sufficient without requiring external articulated rods or complex assembly procedures
2Reliability
If a complex anti-lifting system with multiple components is used, then lifting protection is achieved, but the installation time and implementation difficulty increase
Solution Approach 1:
The anti-lifting function is segmented into simple geometric features: the offset second cylinder, the tubular element with offset axis, and the stop means. These segmented features work together to provide lifting protection while allowing quick installation through simple rotation and alignment, reducing the time and complexity compared to integrated complex systems

AI summary
The invention relates to a post (100) comprising an upright (102), a first cylinder (104) with a first axis of revolution (52) and fixed to the upright (102), a second cylinder (106) with a second axis of revolution (54) offset and fixed to the first cylinder (104), a tubular element (108) pierced with a bore (110) which fits onto the second cylinder (106), where the tubular element (108) has a cylindrical outer surface whose axis of revolution is offset with respect to the second axis of revolution (54), and a stop means (120) which blocks the translation of the tubular element (108) along the second cylinder (106).
