Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional discharge device with a single nozzle is used, then the structure is simple, but the discharge amount is limited and cannot meet high flow rate requirements

Engineering Contradiction:
Improvedischarge amountVSAvoidstructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The discharge device divides the single nozzle into multiple nozzles (first nozzle and second nozzle), where each nozzle has a corresponding discharge port. This segmentation allows the device to achieve higher total discharge amounts while maintaining reasonable structural complexity, as each nozzle can be designed independently and optimized for specific flow requirements.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the discharge amount is increased to meet high flow rate requirements, then the productivity improves, but the risk of clogging increases

Engineering Contradiction:
Improvedischarge amountVSAvoidclogging resistance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

By dividing the discharge system into multiple nozzles with separate discharge ports, the device distributes the total flow rate across multiple pathways. This reduces the flow burden on each individual nozzle, thereby minimizing the risk of clogging while maintaining high overall productivity. The segmented design allows each nozzle to operate within optimal flow parameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each nozzle is designed with specific local characteristics optimized for its function, including tailored nozzle diameters, angles, and discharge port configurations. This local optimization ensures that each nozzle handles its portion of the flow efficiently while being resistant to clogging, contributing to both high productivity and reliability.

Inventive Principle:
Principle #3Local quality

3Productivity

If multiple nozzles are used to increase discharge amount, then the productivity improves, but the device complexity increases

Engineering Contradiction:
Improvedischarge amountVSAvoidnumber of components
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The discharge device merges multiple nozzles and discharge ports into a single integrated housing structure. This combining approach allows the device to achieve high discharge amounts through multiple nozzles while minimizing overall structural complexity by consolidating support structures, mounting mechanisms, and control systems into a unified design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing structure serves multiple functions simultaneously: it supports and positions multiple nozzles, provides structural integrity, facilitates mounting to the sprayer, and enables flow distribution. This multi-functionality reduces the need for separate components, thereby maintaining device simplicity while achieving high productivity through multiple nozzles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a discharge device (20) which is designed to - transfer goods (9) to be conveyed from an upstream conveyor section (10a) at a transfer region (26a), - at least temporarily convey the goods (9) to be conveyed within a conveyor region (26f) in a conveyor direction (FR) and in particular on a conveyor plane (FE), and - selectively discharge the goods (9) to be conveyed in the direction of a discharge region (3) which is arranged laterally in the conveyor direction. The discharge device (20) comprises a plurality of belt slides (21) which are arranged peripherally along a guide (23) such that the belt slides move at least temporarily in the conveyor direction (FR), in particular in the conveyor region (26f). The belt slide comprises a conveyor belt (24), said conveyor belt (24) at least temporarily forming a support surface (241) for the goods (9) to be conveyed, wherein the conveyor belt (24) can be selectively moved in a transverse direction (Q) transversely to the conveyor direction (FR), in particular simultaneously parallel to a conveyor plane (FE), in order to selectively laterally discharge the goods (9) to be conveyed.
