Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dowel-carrying basket assembly methods require additional components and substantial physical effort, leading to increased implementation time and risk of musculoskeletal disorders, as well as inefficiencies in assembly and stiffness.
Innovation Solution
A trellis frame design with longitudinal and transverse threads where dowels are fixed between pairs of weft threads, allowing for elastic bending and secure wedging without additional components, simplifying assembly and reducing physical effort through a spring-like structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components (clips or rubber washers) are used to secure dowels, then the dowel fixation is improved, but the device complexity and implementation time increase
Solution Approach 1:
The patent extracts the fixation function from separate components (clips or rubber washers) and integrates it directly into the trellis frame structure. The transverse wires themselves are designed to elastically deform and secure the dowels, eliminating the need for additional fixation components.
Solution Approach 2:
The trellis frame performs its own fixation function through the elastic properties of its transverse wires. The wires automatically deform to accommodate dowels and then elastic rebound to secure them, making the system self-fixating without requiring separate components or complex assembly procedures.
2Device complexity
If transverse wires are twisted to retain dowels, then additional components are eliminated, but substantial physical effort is required causing musculoskeletal disorders
Solution Approach 1:
The patent changes the mechanical parameter of the transverse wires by specifying their diameter (5-8mm) and material properties to provide optimal elastic deformation characteristics. This allows the wires to flex and secure dowels through controlled elastic rebound rather than requiring manual twisting, significantly reducing physical effort while maintaining fixation capability.
3Ease of operation
If transverse wires are twisted to fix dowels, then assembly is simplified, but the assembly time increases and stiffness is reduced
Solution Approach 1:
The transverse wires are pre-configured with specific diameter and material properties during manufacturing to provide optimal elastic deformation characteristics. This preliminary design ensures that during assembly, the wires can automatically deform and secure dowels through elastic rebound, eliminating the need for time-consuming twisting operations while maintaining assembly simplicity.
4Reliability
If the distance between weft threads is reduced to fit dowels, then the dowel fixation is improved, but the structural flexibility of the frame is reduced
Solution Approach 1:
The patent changes the physical parameters of the transverse wires (diameter of 5-8mm) to provide optimal elastic deformation characteristics. This allows the wires to accommodate dowels of standard dimensions while maintaining sufficient flexibility through controlled elastic rebound, rather than requiring reduced spacing that would compromise frame flexibility.

AI summary
A dowel basket comprising a lattice frame (1) having: - a plurality of longitudinal warp threads (2) straight and parallel to each other; - pairs of transverse weft threads (3, 3') arranged in a portal frame regularly parallel to the warp threads (2); - warp threads (2) being fixed to the uprights (31, 31') of the portal frames to form the lateral sides of the basket. Dowels (20) are fixed transversely to the frame (1) at a ratio of one dowel (20) between the weft threads (3, 3') of each pair, each dowel (20) being fixed in the vicinity of either the free ends of said weft threads (3, 3') of each pair or the crossbar (32) of the portal frame, inserted by force by elastic bending of said weft threads (3, 3').
