Segmented Weighing Plate for Variable-Length Object Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weighing apparatuses struggle to accurately and efficiently weigh objects of different lengths, particularly in industries like food processing where objects vary significantly in length, leading to errors, reduced throughput, and inefficient processing.
Innovation Solution
The apparatus features a weighing plate with multiple segments, each with a specific length, connected by a connecting element with a weighing cell, allowing for precise weight determination of objects of varying lengths by selecting the appropriate weighing cell based on the object's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single large weighing plate is used to accommodate objects of different lengths, then all object sizes can be weighed, but measurement precision deteriorates at the borders of detectable lengths and excessive space is required
Solution Approach 1:
The weighing plate is divided into multiple segments with different lengths, each optimized for specific object size ranges. This segmentation allows the system to maintain high measurement precision for each object length category while still accommodating a broad range of object sizes, resolving the contradiction between versatility and precision.
2Adaptability or versatility
If a long weighing plate is used to weigh longer objects, then longer objects can be weighed, but weighing duration increases and throughput decreases
Solution Approach 1:
By segmenting the weighing plate into multiple sections, the system can process shorter objects on shorter segments, reducing the time each object spends on the weighing plate. This increases the number of objects that can be weighed per unit time, thereby improving throughput while still maintaining the capability to weigh longer objects on extended segments.
Solution Approach 2:
The system dynamically selects which weighing plate segment to use based on the detected length of each object. This dynamic adaptation allows the system to optimize the weighing process for each object, using only the necessary portion of the weighing plate, thus reducing weighing duration and increasing productivity.
3Measurement precision
If excessive spacing is maintained between objects on the weighing plate, then accurate weighing is possible, but the time required for weighing increases
Solution Approach 1:
The segmentation of the weighing plate allows multiple objects to be positioned on different segments simultaneously or in closer succession. This reduces the required spacing between objects while maintaining accurate weighing capability, as each segment can independently process objects without interference from adjacent objects on other segments.

AI summary
An apparatus for weighing objects of different lengths has a transport device with at least one transport element for transporting the objects in a transport direction, a weighing device arranged under the transport element, having a weighing plate with at least two weighing plate segments arranged one behind the other. The weighing plate segments each have a length. A detecting device upstream of the weighing device has at least one detecting unit for detecting the objects length. The first weighing plate segment has at least one weighing cell and generates a weighing signal of an object having a first maximum length. A downstream further weighing plate segment is connected to the first weighing plate segment by a connecting element having at least one weighing cell, and generates a weighing signal of an object having a first or second maximum length. A corresponding mention utilizes the apparatus.
