Concrete Anchor Holder Segmentation and Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor holders for concrete anchors lack efficient mechanisms for secure attachment to concrete forming surfaces and easy removal after concrete curing, leading to difficulties in installation and post-curing detachment.
Innovation Solution
A holder design featuring a base portion with a central projection and coupling system, including a washer or pointed shafts for secure anchoring and easy detachment, allowing for threading into an anchor body and facilitating removal using a tool or segmented threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a holder is designed for secure attachment to concrete forming surfaces, then attachment strength is improved, but removal difficulty increases
Solution Approach 1:
The holder is divided into two main segments: a base portion that attaches to the concrete forming surface and a projection portion with a coupling that holds the anchor. This segmentation allows the base portion to be designed for secure attachment while the coupling mechanism facilitates easy removal, resolving the contradiction between strong attachment and easy removal.
Solution Approach 2:
The holder transitions from a static attached state to a dynamic removable state through the coupling mechanism. The coupling allows the holder to be firmly attached during concrete pouring but can be easily detached after curing, enabling the system to adapt its attachment characteristics based on operational phase.
2Reliability
If a complex coupling system is used for secure anchoring, then attachment reliability is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism merges the anchoring function and the removal function into a single integrated component. The coupling includes both the threaded bore for secure attachment and the structural features for easy removal, eliminating the need for separate complex mechanisms and reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The coupling is designed as a multi-functional component that performs multiple functions: securing the anchor during concrete pouring, maintaining position during curing, and facilitating easy removal after curing. This universality reduces the need for multiple separate components, simplifying the overall device while ensuring reliable attachment.
3Productivity
If installation time is reduced for efficiency, then productivity is improved, but attachment security may be compromised
Solution Approach 1:
The holder is designed with pre-configured attachment features including the base portion with engagement surfaces and the coupling with threaded bores. These features are prepared in advance during manufacturing, allowing for rapid field installation without compromising attachment security, as the critical attachment geometry is already optimized during production.

AI summary
A holder for a concrete anchor comprises a body including a base portion for attachment to a concrete forming surface. The body includes a projection portion extending vertically from the base portion. A coupling is attached to the projection portion at one end of the coupling. The opposite end of the coupling is for threading into an anchor body.
