Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual assembly methods are used with different gripping devices for each profile type, then flexibility in handling different profiles is maintained, but assembly time increases and productivity decreases

Engineering Contradiction:
Improveability to handle different profile typesVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements a universal gripping device with interchangeable gripping elements that can handle different profile types (U-profiles, channel profiles, angle profiles) through a single device platform. The device includes a base body with multiple gripping elements that can be exchanged based on the profile type, eliminating the need for multiple specialized devices while maintaining adaptability.

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

Solution Approach 2:

The gripping device incorporates adjustable and interchangeable gripping elements that can be dynamically configured for different profile types. The device allows for quick changes in gripping configuration through interchangeable elements, enabling rapid adaptation to different profile geometries without requiring complete device replacement.

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple different gripping devices are used for different profile types, then each profile can be gripped optimally, but the number of devices increases and device complexity increases

Engineering Contradiction:
Improvegripping reliability for different profilesVSAvoidnumber of gripping devices
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The gripping device consolidates multiple specialized devices into a single universal platform. The base body accommodates different gripping elements (first, second, and third gripping elements) that can be interchanged based on profile requirements, reducing the total number of devices from multiple specialized units to one multi-functional unit.

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

Solution Approach 2:

The gripping device is segmented into modular components: a base body and interchangeable gripping elements. This segmentation allows the gripping functionality to be divided into separate, specialized elements that can be independently selected and combined, maintaining optimal gripping capability for each profile type while using a single integrated device.

Inventive Principle:
Principle #1Segmentation

3Productivity

If automated assembly is implemented, then productivity increases, but the requirement for specialized gripping devices for each profile type increases device complexity

Engineering Contradiction:
Improveassembly automationVSAvoidgripping device configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The automated assembly system utilizes a universal gripping device that can handle multiple profile types through interchangeable elements. This eliminates the need for multiple specialized gripping devices in the automation system, reducing overall device complexity while maintaining full automation capability for assembling different frame configurations.

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

AI summary

The invention relates to a method, an assembly device, an assembly cell, and a multi-gripping device for the automated assembly of a frame (14) consisting of corner brackets (16) and flange profiles (19) for an air duct element (11). In the method, an assembly device (30) is loaded with flange profiles (19) and corner brackets (16) by a handling device (32). Two opposing corner brackets (16) aligned with a flange profile (19) are inserted into the flange profile (19), forming an assembly group (81). Two opposing assembly groups (81) are inserted into the flange profiles (19) with a free insertion finger (17) of the corner brackets (16) of the assembly group (81) into the flange profiles (19) arranged between them, forming a closed frame (14). (See Figure 5)
