Reversible Saw Tooth Setting for Symmetrical Band Saw Bending

Solution Overview

Problem

Existing saw tooth setting arrangements require high precision and are expensive due to the need for complex designs to achieve symmetrical tooth bending in both directions, which is costly and inefficient.

Innovation Solution

A saw tooth setting arrangement with a reversible base and dual rod elements allows a single saw tooth setting device to set teeth in both directions by using a receiving device that can accommodate the device on both sides of the saw band, enabling precise and symmetrical tooth bending without the need for complex designs or frequent device repositioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a complex saw tooth setting arrangement is used to achieve symmetrical tooth bending in both directions, then manufacturing precision is improved, but device complexity increases and cost increases

Engineering Contradiction:

Improvesymmetrical tooth bending precisionVSAvoidsetting arrangement complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The setting device is designed to perform multiple functions by being usable on both sides of the saw band. A single setting device can set teeth in both directions by positioning it on opposite sides of the band, eliminating the need for separate devices for each direction and reducing overall system complexity while maintaining precision

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of designing separate setting devices for each direction, the invention inverts the approach by making a single device bidirectional. The device is positioned on opposite sides of the saw band to achieve setting in opposite directions, simplifying the overall arrangement while maintaining symmetrical precision

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The invention relates to an arrangement for setting saw teeth on a saw band (4), the arrangement having a base (1) through which the saw band can slide. The base has a receiving device (6) for receiving a saw tooth setting device (8). The saw tooth setting device (8) can set saw teeth in one direction. The receiving device (6) can receive the saw tooth setting device (8) on both sides of the saw band, so that the saw tooth setting device (8) received on one side can set the saw teeth in one direction and so that the saw tooth setting device (8) received on the opposite side can set saw teeth in the opposite direction. This means that although only a simple saw tooth setting device (8) arranged to be able to set saw teeth in one direction is used, the device for setting saw teeth can set them in both directions.
