Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchor testing devices struggle to access and properly test anchors installed in construction sites, especially those in restricted locations, due to limited accessibility, which can lead to inadequate testing and potential structural safety issues.
Innovation Solution
A portable anchor testing device and kit equipped with a load cell sensor, triangularly configured stanchions, leveling devices, and adjustable extensions, allowing for easy access and force application to anchors, including those in hard-to-reach areas, using a load cell sensor support to restrict movement and a force conduit for precise load indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional anchor testing devices are used, then testing can be performed on accessible anchors, but anchors in restricted locations cannot be properly accessed or tested
Solution Approach 1:
The testing device is divided into separate modular components including a head assembly, stanchion, and base plate that can be disassembled and reconfigured. This segmentation allows the device to adapt to different anchor locations and restricted spaces while maintaining testing capability.
Solution Approach 2:
The device incorporates adjustable stanchion heights and movable base plates that can be repositioned dynamically to accommodate anchors in various locations. The ability to adjust and reconfigure the device structure enables access to restricted areas while maintaining proper testing geometry.
2Ease of operation
If a portable testing device is used to access restricted locations, then accessibility improves, but device complexity increases
Solution Approach 1:
The device is designed as a universal testing system that can test various types of anchors in different locations using the same basic configuration. The modular components serve multiple functions - the stanchion provides both structural support and height adjustment, the base plate provides both stability and positioning capability, reducing overall system complexity despite enhanced versatility.
Solution Approach 2:
The device components are designed to nest within each other when not in use, with the head assembly mounting on the stanchion and the base plate folding or nesting with other components. This nesting capability reduces storage space requirements and simplifies transport while maintaining the full functionality of the expanded device.
3Measurement precision
If force is applied through the load cell sensor to test anchor strength, then testing accuracy improves, but device stability requirements increase
Solution Approach 1:
The device uses the reaction force from the anchor itself as a counterweight during testing. When the head assembly applies upward force through the load cell to test the anchor, the anchor's resistance provides a stabilizing counterforce that anchors the device in place, eliminating the need for additional heavy stabilization components while maintaining measurement accuracy.
Solution Approach 2:
The device employs an asymmetric configuration where the head assembly is positioned offset from the center of the base plate, creating a deliberate moment arm that uses the applied test force to enhance stability. This asymmetric design allows the testing force itself to contribute to device stability rather than requiring symmetric, overly complex stabilization mechanisms.

AI summary
An anchor testing device is configured to operate with a load cell sensor and is designed to apply a force through a load cell sensor to an anchor it is testing. The anchor testing device can comprise a top support having a generally centrally located sensor attachment location and three stanchions with each stanchion suspending from a top support and being spaced from the adjacent stanchions. The stanchions can be configured in a generally triangular shape. The device can further comprise a bottom support operatively attached to each stanchion wherein the bottom support and top supports are positioned to maintain the spacing between adjacent stanchions. The device can comprise a load cell sensor support that is positioned below the top support and is operatively attached to the top support or the bottom support. The load cell sensor support is shaped and positioned to engage the load cell sensor and restrict movement of the load cell sensor when the load cell sensor is used with the anchor testing device.
