Weighbridge Load Transfer Assembly Anchor Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weighbridges using compression load cells lack rigidity, requiring a separate anchor or stop to prevent deck displacement, which increases manufacturing costs and installation time.
Innovation Solution
A load transfer assembly that includes a base with a protrusion and a bracket attached to the weighbridge deck, where the protrusion and bracket's opening restrict deck displacement relative to the base, eliminating the need for a separate anchor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If compression load cells are used to determine weight, then the weighing function is achieved, but the weighbridge lacks rigidity and requires a separate anchor or stop to prevent deck displacement
Solution Approach 1:
The patent combines the anchor function and load transfer function into a single integrated load transfer assembly. The assembly includes a base with engagement features that connect to both the deck and the load cell, simultaneously providing structural support and enabling weight measurement without requiring separate anchor components.
Solution Approach 2:
The load transfer assembly serves multiple functions: it acts as an anchor to prevent deck displacement, transfers load to the load cell for weighing, and provides structural support. This multi-functional design eliminates the need for separate anchor or stop components while maintaining weighbridge rigidity.
2Stability of the object's composition
If a separate anchor or stop is installed to prevent deck displacement, then weighbridge rigidity is improved, but manufacturing cost and installation time increase
Solution Approach 1:
The patent merges the anchor function and load transfer function into a single integrated load transfer assembly. The assembly includes a base with engagement features that connect to both the deck and the load cell, simultaneously providing structural support and enabling weight measurement without requiring separate anchor components.
Solution Approach 2:
The load transfer assembly serves multiple functions: it acts as an anchor to prevent deck displacement, transfers load to the load cell for weighing, and provides structural support. This multi-functional design eliminates the need for separate anchor or stop components while maintaining weighbridge rigidity.

Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The load transfer assembly allows for the use of load cells while preventing deck displacement, reducing installation complexity and costs, and enabling quicker installation compared to traditional methods.
Implementation Method 1
use compression load cells instead of shear pins to determine the weight of the load on a weighbridge
Implementation Method 2
the shear pins are deformed and the amount of deformation can be picked up by the strain gauges
Implementation Method 3
the shear pins are deformed and the amount of deformation can be picked up by the strain gauges, the signals from which can be converted to a load
Implementation Method 4
a load transfer assembly configured to transfer displacement of the deck to the load cell
