Semi-Circular Spirit Level for Piling Seat Cut Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straight-edged spirit levels are inefficient and laborious when used to create level seat cuts on circular pilings, as they require manual movement around the circumference of each piling to mark the seat cut accurately.
Innovation Solution
A semi-circular tool with a bull's eye (surface) spirit level, designed to fit around the circumference of a piling, allowing for a single motion to create an accurate level seat cut mark, and can be used in conjunction with laser or transit levels for consistency across multiple pilings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a straight-edged spirit level is used to create level seat cuts on circular pilings, then the marking process can be completed, but it requires manual movement around the circumference of each piling which is inefficient and laborious
Solution Approach 1:
The invention replaces the traditional straight-edged spirit level with a semi-circular level that conforms to the curved surface of circular pilings. This curved design allows the level to be placed directly on the piling circumference without manual movement, enabling the bubble to indicate level positioning automatically around the entire circular surface.
Solution Approach 2:
The invention substitutes the manual mechanical process of moving a straight level around the piling with a static semi-circular level that uses gravitational force on the bubble to indicate level positioning. The bubble's position within the semi-circular vial provides visual feedback for achieving level seat cuts without requiring operator movement or adjustment.
2Manufacturing precision
If a straight-edged spirit level is used on circular pilings, then marking can be achieved, but accuracy and consistency across multiple pilings is difficult to maintain
Solution Approach 1:
The semi-circular level's curved design matches the geometry of the piling surface, providing consistent reference points around the entire circumference. This ensures that seat cut marks are equally accurate at all positions around the piling, maintaining precision without requiring repeated manual adjustments.
Solution Approach 2:
The semi-circular level with its bubble indicator serves itself by automatically showing when the piling surface is level. The bubble's position provides immediate visual feedback, eliminating the need for the operator to make repeated adjustments or check multiple positions manually, thereby reducing time loss while maintaining accuracy.
3Reliability
If a semi-circular level is fabricated from heavy material, then durability is improved, but ease of use and portability deteriorate
Solution Approach 1:
The invention uses aluminum, a lightweight metal with high strength-to-weight ratio, to fabricate the semi-circular level. This material choice provides sufficient durability and rigidity for construction use while keeping the tool light enough for easy carrying and handling by workers throughout the workday.
