Synchronized Ply Assembly for Multi-Ply Panel Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing multi-ply panels for building construction, such as walls and roofs, are time-consuming and expensive, and struggle to incorporate different types of strips for improved insulation and fire-resistance, often resulting in material waste due to the inability to produce panels with integrated openings.
Innovation Solution
A method involving the synchronized displacement of a table and a driving means to assemble layers of structural and filler strips without excessive pressure, allowing for the production of panels with mixed strip materials and integrated openings, using a device with a movable table and synchronized displacement system to maintain strip alignment and apply pressure only where necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If known industrial processes are used to manufacture layers with mixed strip materials, then productivity is improved, but manufacturing precision deteriorates because filler strips are crushed by excessive pressure
Solution Approach 1:
The patent applies a dynamic pressing system that moves synchronously with the layer assembly process. The pressing means travels along with the strips during assembly, applying pressure progressively rather than statically. This dynamic approach allows the layer to be compacted gradually without crushing individual filler strips, resolving the contradiction between achieving good adhesion (requiring pressure) and maintaining strip integrity (requiring low pressure).
Solution Approach 2:
The patent implements preliminary positioning of strips against a stop before pressing begins. The strips are pre-aligned and the assembly plane is established in advance, allowing the synchronized pressing to start from a controlled position. This preliminary action ensures that when pressure is applied during the pressing process, the strips are already in correct positions, preventing misalignment and crushing while maintaining manufacturing precision.
2Manufacturing precision
If lower pressures are applied during assembly, then manufacturing precision is maintained, but adhesive joint strength deteriorates
Solution Approach 1:
The patent employs continuous synchronized pressing throughout the entire layer assembly process. Rather than applying pressure only at the end, the pressing means moves continuously with the assembly, maintaining constant pressure application. This continuous action ensures that adhesive joints develop full strength progressively as each strip is positioned, while the synchronized movement prevents excessive localized pressure that would compromise alignment.
3Manufacturing precision
If handcrafted methods are used to manufacture multi-ply panels, then manufacturing precision is maintained, but productivity deteriorates
Solution Approach 1:
The patent replaces manual handcrafted assembly with an automated mechanical system featuring synchronized pressing means and programmable control. The mechanical system replicates the precision of handcrafted methods through controlled movement and positioning, while dramatically increasing productivity through automation. The synchronized pressing mechanism ensures that industrial-speed assembly maintains the same quality standards as manual processes.
Solution Approach 2:
The patent creates a universal assembly system that can handle multiple strip types (structural wood strips and various filler strips of different materials) with a single standardized process. The synchronized pressing means and modular assembly setup allow the same system to manufacture different panel configurations efficiently, achieving both the versatility needed for mixed materials and the productivity of industrial processes.
4Ease of manufacture
If known methods are used to produce panels, then ease of manufacture is maintained, but adaptability deteriorates because integrated openings cannot be produced
Solution Approach 1:
The patent implements segmentation by allowing individual strips to be positioned and assembled with gaps between them, creating integrated openings as part of the assembly process rather than adding them later. The synchronized pressing system accommodates these gaps naturally, pressing only where strips are present. This segmentation approach enables flexible panel configurations (windows, doors, recesses) while maintaining the simplicity of a single-pass assembly process.

AI summary
There is a method for producing a ply involved in the construction of a multi-ply panel for constructing or adding to a wall, floor or ceiling, or a sloping part for a building. The ply includes a juxtaposition of strips, either structural strips or filling strips, positioned between the structural strips and made of a different material from that of the structural strips. The materials are selected for the thermal or acoustic insulation thereof, the thermal inertia thereof or the fire résistance thereof. Each lateral movement of a ply being produced with respect to the assembly plane is carried out by the synchronized movement of a table with which the lower face of the ply is in contact and a driver with which the upper face of the ply is in contact. There is an installation for implementing the method according to the invention.
