Concrete Forming Stake With Rotatable Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional concrete forming stakes puncture vapor barriers, compromising their integrity and allowing moisture vapor to pass through, and require precise alignment and placement, which can be inconvenient, especially on uneven surfaces.
Innovation Solution
A concrete forming apparatus featuring a base member that can be secured to a surface with adhesion or mechanical fasteners, allowing a rotatable stake to be positioned without piercing the vapor barrier, and incorporating channels for easy fastener placement, enabling flexible support and alignment of concrete forms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional steel stakes with spikes are hammered into the subgrade to support concrete forms, then the stakes provide support and resistance to movement, but the stakes puncture vapor barriers and reduce their utility
Solution Approach 1:
The stake is divided into separate functional components: a base member that interfaces with the vapor barrier and subgrade, and a stake portion that provides form support. This segmentation allows the base to preserve vapor barrier integrity while the stake portion maintains structural support function.
Solution Approach 2:
A base member serves as an intermediary component between the stake and the vapor barrier/subgrade interface. This base member provides alternative attachment methods (adhesive layers, mechanical fasteners) that do not puncture the vapor barrier, while still enabling the stake to fulfill its support function.
2Manufacturing precision
If stakes are hammered into the subgrade at precise angles to position them perpendicular to the surface, then proper alignment is achieved, but the placement process becomes inconvenient on uneven surfaces
Solution Approach 1:
The stake assembly incorporates rotational freedom through a rotatable connection between the stake portion and base member, allowing the stake to be positioned at various angles after insertion. This dynamic adjustment capability eliminates the need for precise initial alignment during placement, significantly improving ease of operation on uneven surfaces.
Solution Approach 2:
The invention adds a rotational degree of freedom to the stake system. Instead of requiring precise angular placement in one dimension, the stake can be inserted in any orientation and then rotated to the correct position, transforming a one-dimensional alignment problem into a two-dimensional positioning solution.
