Problem

Existing machines for cutting wood panels face challenges in efficiently executing inclined cuts due to the manual positioning of a second stop element, which results in lengthy tooling times and increased risk of positioning errors.

Innovation Solution

A machine with a stop device comprising an elongated bar, a guide, a sliding nut screw mechanism, and a rotatable stop element, allowing for precise and rapid adjustment of panel orientation for inclined cuts, eliminating the need for manual positioning of the second stop element.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If manual positioning of the second stop element is used, then the machine structure remains simple, but the tooling time increases and positioning accuracy deteriorates

Engineering Contradiction:
Improvetooling timeVSAvoidstop device complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The second stop element is made mobile along the guide instead of being fixed in predetermined seats. The actuating device allows the stop element to be quickly positioned at any location along the guide, transforming the system from static to dynamic and enabling rapid adjustment without manual intervention in predetermined positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The manual positioning mechanism is replaced with an actuating device that automatically positions the second stop element. This substitution eliminates the need for operators to manually place the stop element in predetermined seats, significantly reducing tooling time and improving positioning consistency.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual positioning of the second stop element is used, then the device complexity remains low, but the positioning precision deteriorates due to operator errors

Engineering Contradiction:
Improvepositioning accuracyVSAvoidstop device complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The actuating device provides controlled, repeatable positioning of the second stop element along the guide. The system eliminates human error in positioning by using a mechanical or automated feedback-controlled mechanism that can accurately place the stop element at the desired location without operator intervention.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The stop device is designed to automatically position itself through the actuating mechanism. The system performs the positioning function autonomously without requiring external manual intervention, ensuring consistent and accurate positioning while reducing dependence on operator skill and attention.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If predetermined seats for the second stop element are provided, then the device structure remains simple, but the adaptability deteriorates as only specific angles are available

Engineering Contradiction:
Improvepanel orientation flexibilityVSAvoidstop device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The second stop element transitions from being constrained to fixed predetermined seats to being mobile along a continuous guide. This dynamic configuration allows the stop element to be positioned at any location along the guide, enabling versatile panel orientations and angles beyond fixed predetermined positions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The positioning capability transitions from discrete predetermined points (0D/1D) to continuous positioning along the guide (1D). This dimensional expansion allows the second stop element to accommodate any angle within the guide's range, significantly improving adaptability for different panel orientations.

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