Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If test weights are attached to the weighing device for adjustment, then the weighing device can be calibrated, but the process becomes complex and time-consuming due to difficult access in enclosed systems
Solution Approach 1:
A holder is introduced as an intermediary component that simplifies the attachment of test weights to the weighing device. The holder can be easily attached and detached from the weighing device, providing a convenient interface for calibration operations without requiring direct manipulation of the weighing device itself.
Solution Approach 2:
The holder is designed to be dynamically attachable and detachable from the weighing device, allowing flexible access for calibration operations. This dynamic connection enables operators to easily attach test weights during maintenance periods without permanent modifications to the weighing device.
2Measurement precision
If test weights are attached to the weighing device, then calibration can be performed, but the process takes excessive time especially with enclosed conveying devices
Solution Approach 1:
The holder is pre-positioned on the weighing device during manufacturing, so that during operation only the test weight needs to be attached to the holder for calibration. This preliminary setup significantly reduces the time required for calibration operations compared to attaching test weights directly to the weighing device.
Solution Approach 2:
The holder serves as a mediator that enables quick attachment and detachment of test weights. By separating the attachment mechanism from the weighing device itself, the calibration process becomes faster and simpler, especially for enclosed conveying devices where access is limited.
3Ease of operation
If permanent holders are installed on the conveying device for test weights, then adjustment is facilitated, but the holders may protrude and be affected by external factors like dirt and wind
Solution Approach 1:
The holder is designed with a dynamic attachment system that allows it to be securely fixed during calibration operations but easily removed when not in use. This dynamic capability enables the holder to be positioned inside the enclosed conveying device during calibration, protecting it from environmental factors like dirt and wind, while still providing easy access for operators.
Solution Approach 2:
The holder can be nested within or attached to existing components of the conveying device, such as the frame or support structures, in a position that is protected from external environmental factors. This nesting approach allows the holder to remain accessible for calibration while being shielded from dirt, wind, and other harmful external influences.

AI summary
The invention relates to a conveyor and metering device comprising an endless conveyor belt (5), wherein sub-regions of the conveyor belt (5) are mounted on weighing devices (2) in order to ascertain the mass of the conveyed goods, said weighing devices being connected to an electronic analysis device. The weighing devices generate a signal which is proportional to the load on the conveyor belt (5) and transmit same to the analysis device. The conveyor and metering device is provided with weighing devices (2) with a respective bearing bracket (22) which is used to receive an attachment (3) from the outside, preferably from above through an opening in the frame of the conveyor and metering device, in a formfitting manner during a conveyor operation.
