Solution Overview

Problem

Conventional wire saws require multiple personnel to operate due to the distance between the actuating device for wire tensioning and the wire saw, making preparation and operation costly and inefficient.

Innovation Solution

Integrating the actuating device for wire tensioning directly onto the wire saw's drive and storage unit or providing it as a constituent of a remote control device, allowing a single person to manage wire tensioning and reduce personnel requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the actuating device for wire tensioning is arranged on a remote control panel several meters away from the wire saw, then safety is improved by separating the control from the hazard zone, but the number of personnel required increases and operational efficiency deteriorates

Engineering Contradiction:
ImprovesafetyVSAvoidoperational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The actuating device is integrated directly onto the drive and storage unit of the wire saw, eliminating the spatial separation between control and execution. This allows the operator to control wire tensioning at the same location where the wire is being fitted, reducing personnel requirements while maintaining safety through proper device design

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

2Productivity

If the actuating device is integrated directly on the drive and storage unit of the wire saw, then the number of personnel required is reduced and operational efficiency is improved, but the complexity of the wire saw increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidwire saw complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The actuating device for wire tensioning is merged with the drive and storage unit of the wire saw, combining previously separate functions into a single integrated assembly. This integration reduces the number of separate components and connections needed, thereby reducing overall system complexity despite adding functionality to the drive unit

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple personnel are required to fit the wire into the wire store, then wire tensioning control is separated from the operator, but preparation time increases and cost increases

Engineering Contradiction:
Improvecontrol separationVSAvoidpreparation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The wire tensioning function is made self-service by integrating the actuating device directly on the drive and storage unit, allowing the operator to independently control wire tensioning while fitting the wire into the wire store. This eliminates the need for a second person to operate a remote control panel, reducing preparation time and costs while maintaining proper control separation through integrated design

Inventive Principle:
Principle #25Self-service
