Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of securing posts, such as those in fences, often involves maintaining vertical orientation during concrete filling, which can be challenging due to post movement, requiring frequent level checks and adjustments.
Innovation Solution
A post levelling device with a support frame, adjustable legs, level indicators, and securing members that can be easily attached to the post, allowing for precise vertical alignment and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a spirit level is held against the post during concrete filling, then the post level can be checked, but the post cannot be securely maintained in vertical orientation due to movement during filling
Solution Approach 1:
The device sets up the support frame and adjustable legs to establish vertical alignment before concrete filling begins. The level indicators show when the post is vertically aligned in advance, allowing the post to be secured in the correct position during the filling process without needing continuous manual adjustment.
Solution Approach 2:
The support frame acts as an intermediary device between the post and the worker. It provides a stable reference structure with level indicators that mediate the alignment process, eliminating the need to manually hold the spirit level against the moving post during concrete filling.
2Reliability
If the post is manually held vertical during concrete filling, then vertical orientation can be maintained, but frequent checking and adjusting is required due to post movement
Solution Approach 1:
The level indicators provide continuous visual feedback on the post's vertical alignment through the support frame. This feedback mechanism allows workers to see immediately when the post is correctly positioned, eliminating the need for frequent manual checking and adjustment during the concrete filling process.
Solution Approach 2:
The device allows the post to essentially level itself through the adjustable legs and support frame system. The level indicators show when vertical alignment is achieved, and the adjustable legs can be modified to maintain this alignment without requiring constant manual intervention during concrete filling.
3Reliability
If a support device is added to maintain post verticality, then post alignment stability is improved, but device complexity and number of components increases
Solution Approach 1:
The device is divided into distinct functional segments: a support frame with first and second legs, level indicators mounted on the frame, and securing members. This segmentation allows each component to perform its specific function independently while keeping the overall structure relatively simple and easy to assemble.
4Manufacturing precision
If adjustable legs are provided to engage with the ground, then the support frame can be oriented vertically, but the device structure becomes more complex
Solution Approach 1:
The legs are made adjustable in length, transforming a static structure into a dynamic one that can adapt to different ground conditions and post heights. This adjustability allows the support frame to achieve precise vertical orientation while maintaining relatively simple construction through straightforward adjustment mechanisms.
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
The device ensures the post remains vertically aligned during securing, reducing the need for frequent adjustments and facilitating efficient concrete filling by providing a stable and adjustable support system.
Implementation Method 1
each of the first and second level indicators comprises a spirit level tube mounted between adjacent sides of the flanges above the first ends of the legs

AI summary
A post levelling device (10) comprising a support frame (12) engageable with a post (22). First and second legs (14, 16) are provided extending outwardly from support frame (12) such that the first and second legs (14, 16) are oriented in perpendicular first and second vertical planes. First and second level indicators (38, 40) arranged to indicate the angle of the support frame (12) relative to the vertical in each of the first and second vertical planes. One or more securing members (36, 37) extend from the support frame (12) to secure around the post (22). The first and second legs (14, 16) are length adjustable such that lower ends of the first and second legs (14, 16) may be engaged with the ground adjacent the post (22) and shortened or lengthened to adjust the support frame (12) to be oriented vertically.
