Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional gluing methods are used to connect lamellae, then the furniture component achieves structural integrity, but the production process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the chemical gluing process with a mechanical cutting process. High-energy cutting processes (water jet or laser cutting) are used to create separating sections in the base body, which automatically forms connecting sections between lamellae. This substitution eliminates the need for glue application, alignment, clamping, and drying steps, significantly simplifying the production process while maintaining structural integrity through the mechanically formed connecting sections.
Solution Approach 2:
The patent extracts the connecting sections from the base body through selective cutting. By removing material at specific locations to create separating sections, the connecting sections are automatically formed and extracted as integral parts of the base body structure. This approach eliminates the need for separate connection components and simplifies the overall manufacturing process.
2Strength
If traditional gluing methods are used to connect lamellae, then the furniture component achieves structural integrity, but the production time increases due to drying time
Solution Approach 1:
The patent replaces the time-consuming chemical gluing process with an immediate mechanical cutting process. The high-energy cutting processes (water jet or laser cutting) create the separating and connecting sections in a single operational step without requiring drying time. The structural integrity is achieved immediately upon completion of the cutting process, eliminating the waiting period associated with adhesive curing.
Solution Approach 2:
The patent performs the forming of connecting sections as a preliminary action during the base body fabrication process itself. By integrating the creation of separating and connecting sections into the base body manufacturing step, the structural integrity is established before final assembly, eliminating subsequent time-consuming joining operations and their associated drying times.
3Strength
If traditional gluing methods are used to connect lamellae, then the furniture component achieves structural integrity, but the production cost increases
Solution Approach 1:
The patent replaces the multi-step chemical gluing process with a single-step mechanical cutting process using high-energy cutting methods. This substitution eliminates the need for glue materials, application equipment, clamping devices, and the labor-intensive alignment and monitoring processes, thereby reducing both material costs and manufacturing overhead while maintaining structural integrity through the precisely formed connecting sections.
Solution Approach 2:
The patent merges the formation of separating sections and connecting sections into a single cutting operation. By combining these functions into one integrated process step performed on the base body, the patent eliminates the need for separate operations for each type of section, reducing process complexity and production costs while ensuring structural integrity through the unified design approach.
4Strength
If traditional gluing methods are used to connect lamellae, then the furniture component achieves structural integrity, but the shaping freedom is limited
Solution Approach 1:
The patent replaces the constraint-imposing gluing process with a flexible cutting process. High-energy cutting methods (water jet or laser cutting) can easily accommodate complex geometries and varying shapes without the limitations of glue joint design. The connecting sections are formed by removing material rather than adding it, allowing for greater design freedom and adaptability in shaping the base body and its lamellae while maintaining structural integrity through the cut-formed connections.

AI summary
The method involves providing a main body (30) and carrying out a cutting process on the main body for generating a separating section (22b) between fins (22) while maintaining a connecting portion (22a). A cutting gap is generated by width of less than about 1 mm. The main body is made of a wood fiber material, which comprises a binder. Cutting edges are grinded, and a surface of the main body is coated. A peripheral edge of the main body is cut, and the surface of the main body is coated. An independent claim is also included for a furniture component.
