Segmented Drying Units for Painted Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying devices for painted workpieces lack flexibility in drying times, as they are designed for a predetermined dwell time, preventing the accommodation of varying workpiece lengths and requiring movement during the drying process.
Innovation Solution
A drying device with multiple units, each capable of maintaining a constant temperature, equipped with a control unit, distribution device, and timing system, allowing for independent drying times and storage of workpieces, enabling flexible drying times and rest during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a drying tunnel with predetermined dwell time is used, then the drying process is simple and continuous, but flexible drying times cannot be achieved and workpieces must move through the tunnel in a predetermined time
Solution Approach 1:
The drying device is divided into multiple independent drying units (first drying unit, second drying unit, etc.), each capable of independently drying workpieces for different durations. This segmentation allows flexible drying times by selecting appropriate units while maintaining overall system simplicity through modular design.
Solution Approach 2:
The system dynamically assigns workpieces to different drying units based on required drying times. The control system can adaptively manage which workpiece goes to which drying unit, enabling flexible drying schedules without requiring complex real-time adjustments to the drying units themselves.
2Ease of operation
If workpieces are transported through a drying tunnel, then drying can be performed continuously, but workpieces experience movement and cannot rest during the drying process
Solution Approach 1:
By dividing the drying process into separate stationary drying units, workpieces can remain at rest in one unit throughout their drying cycle. This eliminates the need for continuous movement through a tunnel while maintaining productivity through parallel operation of multiple drying units.
Solution Approach 2:
The distribution device acts as an intermediary that transports workpieces to the appropriate drying units and then allows them to remain stationary. This mediator handles the movement aspect while the drying units provide stable, motionless drying environments.
3Adaptability or versatility
If multiple drying units with independent control are used, then flexible drying times are achieved, but the device complexity increases
Solution Approach 1:
Multiple drying units share common infrastructure including heating means, control systems, and distribution mechanisms. Each drying unit is a simplified replica that performs the same basic function, reducing overall complexity compared to a single complex continuously-variable system.

Function Achieved in This Case
Enables flexible drying times and reduces movement during the drying process, ensuring high surface quality and efficient drying of workpieces of different lengths and materials.
Implementation Method 1
heating means (13) which are set up to maintain a constant temperature in the drying device and in each of the drying units
Implementation Method 2
at least one distribution device (3), wherein the workpieces can be stored in the drying units by means of the distribution device and/or can be swapped out
Implementation Method 3
the control unit has a timing device, a memory and a processor for determining the dwell time of the workpieces in each of the drying units
Implementation Method 4
The evaporation process of the painted workpieces takes place preferably at room temperature in the evaporation device. During the evaporation process, the volatile parts of a paint applied to a workpiece evaporate.
Implementation Method 5
The drying process of the painted workpieces takes place in the drying units of the drying device... The term drying is to be understood as any type of crosslinking, polymerizing and curing of material, in particular curing a paint by radiation.
