Post Anchor Bracket with Rotating Plates for Moisture Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commonly known building structure anchor brackets fail to provide rotary adjustment of attached construction posts and insecurely anchor within concrete foundations, exposing wooden members to moisture, leading to water rot.
Innovation Solution
The anchor bracket features a vertically stacked pair of rotatable plates with rotating means, such as lug and travel slot combinations, and releasable locking mechanisms, along with 'A' plate configured arms for secure concrete anchoring and a flow-through riser element to prevent water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If commonly known anchor brackets are used, then the bracket structure is simple, but the post cannot be rotated or adjusted after installation
Solution Approach 1:
The bracket is divided into multiple segments including a base plate, post plate, and adjustable arm segments connected by pivot points. This segmentation allows each component to rotate independently relative to others, enabling post rotation and adjustment while maintaining overall structural integrity.
Solution Approach 2:
The bracket transitions from a static fixed structure to a dynamic adjustable structure through the incorporation of pivot points and rotation mechanisms. The post plate can rotate relative to the base plate, and arms can be adjusted to different positions, providing operational flexibility after installation.
2Reliability
If commonly known anchor brackets are used, then the manufacturing process is simple, but the anchoring security within concrete foundation is insufficient
Solution Approach 1:
The anchoring system is segmented into multiple independent anchoring arms extending from the base plate. Each arm can be independently formed and welded to the base plate, allowing for secure embedding in concrete while maintaining manufacturing feasibility through modular construction.
Solution Approach 2:
The anchoring arms are formed with curved or angled configurations rather than straight rigid extensions. This curvature allows the arms to better distribute mechanical loads and conform to the concrete foundation, improving anchoring security while being formable through standard manufacturing processes.
3Object-affected harmful factors
If commonly known anchor brackets are used, then the structure is simple, but wooden members are exposed to moisture and water rot
Solution Approach 1:
The design extracts or removes the wooden post from direct contact with moisture-prone areas by elevating it through the bracket structure. The post plate and arm configuration positions the wooden member away from the concrete foundation where moisture accumulates, preventing water rot while adding structural complexity.
Solution Approach 2:
The metal bracket components serve as intermediary elements between the wooden post and the concrete foundation. These intermediaries create a physical barrier and spatial separation that prevents moisture from the concrete from directly contacting and damaging the wooden member.
4Adaptability or versatility
If commonly known anchor brackets are used, then the installation is straightforward, but the post rotational orientation is fixed and cannot be adjusted
Solution Approach 1:
The bracket incorporates dynamic rotation capabilities through pivot points that allow the post plate to rotate relative to the base plate. This enables adjustment of the post's rotational orientation to various angles while maintaining a secure connection, transforming a static installation into an adjustable system.
Solution Approach 2:
The rotation and adjustment mechanisms are pre-configured into the bracket structure during manufacturing, with pivot points and connection geometries designed to enable rotation. This preliminary configuration allows for easy field adjustment without requiring complex installation procedures or additional components.
