Solution Overview

Problem

Existing machining devices for metal workpieces require complex relative movements between the workpiece and tool, which can be inefficient and prone to imbalance during angled machining operations.

Innovation Solution

A device where the holding adapter is mechanically coupled to a rotary device, allowing the clamping part to be held at an angle to the axis of rotation, enabling simple perpendicular movements for machining without complex relative movements, and incorporating a compensating device to balance the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complex relative movements are used between workpiece and tool for angled machining, then machining capability is improved, but device complexity and operational stability deteriorate

Engineering Contradiction:
Improvemachining capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of moving the tool or workpiece in complex relative movements to achieve angled machining, the invention inverts the approach by fixing the clamping element at a predetermined angle to the axis of rotation. This allows angled machining to be achieved through simple perpendicular movements of the tool or workpiece, thereby reducing device complexity while maintaining machining capability.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If complex relative movements are used between workpiece and tool for angled machining, then machining capability is improved, but operational stability deteriorates

Engineering Contradiction:
Improvemachining capabilityVSAvoidoperational stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The invention stabilizes the system by inverting the conventional approach: rather than relying on complex relative movements between tool and workpiece, the clamping element is fixed at a predetermined angle to the axis of rotation. This reduces dynamic complexity during operation, thereby improving operational stability while still enabling angled machining through simple perpendicular movements.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of operation

If simple perpendicular movements are used for machining, then operational simplicity is improved, but machining capability for angled surfaces deteriorates

Engineering Contradiction:
Improveoperational simplicityVSAvoidmachining capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The invention introduces asymmetry by fixing the clamping element at a predetermined angle (different from the axis of rotation) rather than aligning it parallel to the axis. This asymmetric arrangement enables angled machining surfaces to be produced through simple perpendicular movements, thereby maintaining operational simplicity while enhancing machining capability for angled surfaces.

Inventive Principle:
Principle #4Asymmetry

4Ease of operation

If clamping element is fixed at an angle to axis of rotation, then operational simplicity is improved, but imbalance during rotation worsens

Engineering Contradiction:
Improveoperational simplicityVSAvoidimbalance
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention compensates for the imbalance caused by the angularly fixed clamping element by providing a counterweight that offsets the centrifugal forces generated during rotation. This allows the system to maintain operational simplicity with the angled clamping element while eliminating the harmful imbalance that would otherwise occur during rotational machining operations.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
