Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gouging machines for double reed production face challenges in achieving consistent dimensions and centering due to natural variations in bamboo cane curvature, leading to inconsistent reed quality.
Innovation Solution
The implementation of a filiere with edge gripping cane clamps that apply uniform downward forces to ensure consistent contact with the cane bed trough, combined with a gouging machine featuring adjustable wedges for precise adjustments, allowing for self-leveling and precise control during the gouging process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional gouging machines use a fixed circular trough to support the cane, then the structure is simple and easy to manufacture, but the cane curvature variations cause inconsistent contact and poor manufacturing precision
Solution Approach 1:
The patent applies the dynamics principle by making the trough adjustable rather than fixed. The trough can be repositioned along the cane length and its curvature can be modified to match the natural variations in cane shape, allowing the system to adapt dynamically to different cane geometries and achieve consistent contact throughout the gouging process.
Solution Approach 2:
The patent implements parameter changes by allowing the trough curvature radius and position to be varied. The trough curvature radius can be adjusted to match different cane curvatures, and the trough position can be changed along the cane length, enabling the system to accommodate natural variations in cane geometry and maintain consistent contact.
2Manufacturing precision
If the cane curvature does not match the trough curvature, then the gouging process is simpler, but the reed quality and dimensional consistency deteriorate
Solution Approach 1:
The patent applies parameter changes by making the trough curvature radius adjustable to match different cane curvatures. This allows the system to adapt to natural variations in cane geometry, ensuring consistent contact between the cane and trough throughout the gouging process, thereby improving reed dimensional consistency.
Solution Approach 2:
The patent implements dynamics by allowing the trough to be repositioned and reconfigured during operation. The trough can be moved to different positions along the cane and its curvature can be adjusted, enabling the operator to optimize the match between trough and cane geometry for each specific piece of cane being processed.
3Manufacturing precision
If manual centering of cane in the trough is used, then the device complexity is reduced, but the centering accuracy and reed quality decrease
Solution Approach 1:
The patent applies dynamics by implementing an adjustable positioning mechanism that allows the trough to be moved to different positions along the cane. This dynamic positioning capability enables precise centering of the cane in the trough, improving centering accuracy without requiring overly complex fixed positioning structures.
Solution Approach 2:
The patent implements universality by designing a positioning mechanism that serves multiple functions: it centers the cane in the trough, maintains consistent contact during gouging, and can be adjusted for different cane sizes and curvatures. This multi-functional approach achieves high centering accuracy without proportionally increasing device complexity.

AI summary
A filiere for trimming cane includes: (a) a body having a trough extending inward from a flat surface; (b) a blade fastened to the body so that a cutting edge extends across the trough; (c) a hold-down mechanism positioned proximate to the blade; and (d) a force application mechanism in contact with the hold-down mechanism which causes the hold-down mechanism to press edges and a center of the cane against the trough proximate the cutting edge.
