Solution Overview

Problem

Existing apparatuses for bending elongated metal products require manual replacement and recalibration of bending units, leading to prolonged downtime, increased costs, and the need for specialized personnel and additional storage space, which complicates and prolongs the production process.

Innovation Solution

An apparatus with an automated exchanger device that alternates between a bending zone and a storage area, allowing seamless switching between different bending units without manual intervention, minimizing downtime and storage requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual replacement and resetting of bending units is performed, then different bracket geometries can be produced, but production downtime increases and specialized personnel are required

Engineering Contradiction:
Improveability to produce different bracket geometriesVSAvoidproduction downtime
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs automatic self-calibration through the calibration device, eliminating the need for specialized personnel to manually replace and calibrate bending units. The calibration device automatically adjusts the bending parameters when a new unit is installed, making the system self-servicing and reducing both downtime and personnel requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The calibration device pre-configures and stores calibration data for different bending units. When a new bending unit is installed, the system automatically retrieves and applies the pre-stored calibration data, eliminating the need for time-consuming manual calibration procedures and reducing production downtime.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual calibration operations are performed, then new brackets can be produced with required tolerances, but time and metal material are wasted

Engineering Contradiction:
Improvebracket toleranceVSAvoidcalibration time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system replaces manual mechanical calibration operations with an automated calibration device that uses sensors and control systems to automatically adjust and verify bending parameters. This substitution ensures required tolerances are met while eliminating time-wasting manual procedures and reducing metal material waste from test bends.

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

3Adaptability or versatility

If a magazine for storing bending units is provided, then production needs are covered, but space and management costs increase

Engineering Contradiction:
Improvecoverage of production needsVSAvoidstorage space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The calibration device serves multiple functions: it calibrates bending units, stores calibration data for multiple unit types, and automatically selects the appropriate calibration parameters. This multi-functionality eliminates the need for a dedicated magazine, as the system can handle different bending unit types through its universal calibration capability, reducing storage space requirements while maintaining production versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
