Solution Overview
Problem
Existing deburring tools lack precision and reproducibility in processing burrs on elongated objects like skis, resulting in uneven and rounded edges that affect edge sharpness and performance.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single plate-shaped grinding wheel is used for deburring, then the structure is simple and easy to manufacture, but the processing precision and edge sharpness are insufficient
Solution Approach 1:
The single grinding wheel is divided into two separate burr processing elements (first and second burr processing elements) with different orientations. The first burr processing element has a burr processing surface oriented at a shallow angle to the guide surface, while the second burr processing element has a burr processing surface oriented at a steep angle or substantially perpendicular to the guide surface. This segmentation allows each element to perform a specific function in the deburring process, improving overall processing precision.
Solution Approach 2:
Different portions of the burr processing device are assigned different properties - the first burr processing element uses a shallow angle orientation for initial burr engagement, while the second burr processing element uses a steep angle for final edge definition. This local differentiation of geometric properties enables precise control over the burr transformation at different stages of the processing sequence.
2Manufacturing precision
If deburring is performed in only one direction, then the process is simple, but the edge sharpness and reproducibility are compromised
Solution Approach 1:
The device enables dynamic multi-directional burr processing by sequentially engaging the burr with the first and second burr processing elements in a controlled sequence. The elongated object is guided along the guide surface such that the burr first contacts the first burr processing element and then the second burr processing element, allowing the processing direction to change from shallow angle to steep angle orientation during the same operation.
Solution Approach 2:
The invention adds a dimensional aspect to the deburring process by introducing a second burr processing element oriented at a different angle (steep angle or perpendicular) relative to the first element. This creates a multi-dimensional processing approach where the burr is transformed through sequential angular orientations, improving edge sharpness and reproducibility.
3Manufacturing precision
If the burr is not processed in a controlled sequence, then the operation is simple, but the reproducibility and accuracy are reduced
Solution Approach 1:
The device is designed with the burr processing elements positioned and oriented in advance along the guide surface, so that when the elongated object is guided through the device, the burr automatically engages with the first processing element first and then the second processing element second. This preliminary arrangement of processing elements ensures a controlled and repeatable processing sequence without requiring active control mechanisms.

Implementation Method 1
the first burr processing element (2) which has a first burr processing surface (3) oriented at a shallow angle or in line with the guide surface (1), and a second burr processing element (5) with a second burr processing surface (6) oriented at a steep angle or at a right angle to the guide surface (1). As the burr passes through the device according to the invention, it is first bent in a first direction by the first burr processing element (2) and then in a second direction by the second burr processing element (5).
