Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a robotic device is used for handling burners, then positioning flexibility and automation are improved, but device complexity, installation time, and cost increase significantly

Engineering Contradiction:
Improvepositioning flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The handling device is divided into separate functional components: a base body for attachment to the burner, rotatable arms for positioning, and receiving means for lifting appliance integration. This segmentation allows each component to be optimized independently and simplifies installation and maintenance while maintaining positioning flexibility through the modular assembly.

Inventive Principle:
Principle #1Segmentation

2Extent of automation

If a robotic device is used for handling burners, then automation is improved, but installation time and cost increase significantly

Engineering Contradiction:
ImproveautomationVSAvoidinstallation time
Core Design Contradiction:
Extent of automationVSLoss of time

Solution Approach 1:

The handling device is designed to be self-installed using standard lifting appliances and common fastening methods. The base body can be directly attached to the burner rear end surface using existing holes, and the arms can be rotated into position and locked with quick release pins, eliminating the need for complex professional installation procedures and reducing installation time significantly.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If a robotic device is used for handling burners, then positioning flexibility is improved, but cost increases significantly

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The handling device uses simple, inexpensive components such as steel arms, basic fastening mechanisms with quick release pins, and standard receiving means that can be manufactured at low cost. These components are designed to be robust yet simple enough for economical production, replacing expensive robotic systems while maintaining adequate functionality for burner handling and positioning.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Stability of the object's composition

If fixed arms are used in the handling device, then structural stability is improved, but positioning flexibility for different burner orientations deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidpositioning flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The arms are made rotatable relative to the base body through bearing connections, allowing dynamic adjustment of arm positions to match different burner orientations. Quick release pins provide locking mechanisms that secure the arms in selected positions during operation, combining structural stability when locked with positioning flexibility when adjustment is needed.

Inventive Principle:
Principle #15Dynamics
