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

A device with a guide surface and two burr processing elements, one at a shallow angle and the other at a steep angle, that sequentially process the burr as the object moves along, allowing for precise control and adjustment of processing angles to achieve a defined sharp edge.

Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveburr processing precisionVSAvoiddevice structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If deburring is performed in only one direction, then the process is simple, but the edge sharpness and reproducibility are compromised

Engineering Contradiction:
Improveedge sharpnessVSAvoidprocessing sequence
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Engineering Contradiction:

Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.
