Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decoration plants for bituminous membranes are limited in creating complex and non-geometrically restricted designs, primarily orienting decorations parallel to the membrane's length, which can lead to water leakage issues during installation on pitched roofs.
Innovation Solution
A plant with synchronized depositing apparatuses and a control unit that adjusts the speed of the bituminous membrane and transfer members to allow for decorations oriented transversely, enabling complex patterns and preventing water infiltration by synchronizing the actuation speeds and movement speed of the membrane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If decorations are oriented parallel to the membrane's length, then the deposition process is simplified, but water leakage issues occur during installation on pitched roofs
Solution Approach 1:
The patent implements a synchronized control system that dynamically adjusts the speed of multiple depositing apparatuses based on real-time coordination. The control unit receives position signals from encoders and dynamically calculates the required speed for each apparatus to achieve transverse decoration orientation, transforming a static sequential deposition process into a dynamic coordinated system that prevents water leakage while maintaining manufacturing feasibility
2Ease of operation
If simple geometric shapes are used for decorations, then the depositing apparatus is easier to operate, but the range of obtainable decorations is limited
Solution Approach 1:
The patent divides the decoration deposition process into multiple independent apparatuses, each responsible for specific portions of the overall pattern. The control unit segments the decoration design into coordinate-based instructions for each apparatus, allowing complex non-geometric shapes to be constructed through coordinated action of multiple simpler depositing units, thereby maintaining operational simplicity while expanding design versatility
Solution Approach 2:
The patent introduces a transverse orientation dimension to the decoration patterns, perpendicular to the membrane's longitudinal direction. This dimensional change enables completely new decoration configurations that were previously unachievable with parallel-only deposition, expanding the design space from one-dimensional linear patterns to two-dimensional transverse patterns while using the same basic apparatus components
3Adaptability or versatility
If multiple depositing apparatuses are used in series, then complex decorations can be created, but coordination of actuation speeds becomes more difficult
Solution Approach 1:
The patent implements a feedback control system where encoders on each depositing apparatus continuously monitor position and speed, feeding this information back to the central control unit. The control unit processes this feedback and dynamically adjusts the actuation speeds of all apparatuses to maintain precise coordination, enabling complex transverse decorations to be created automatically without manual speed coordination difficulty
