Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If sorting elements are securely attached with screws or welded, then attachment strength is improved, but attachment time and complexity increase

Engineering Contradiction:
Improveattachment strengthVSAvoidattachment time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical fastening methods (screws, welding) with a magnetic attachment system. Magnets embedded in the sorting bowl and corresponding magnetic elements in the sorting elements create secure attachment through magnetic attraction, eliminating the need for tools and complex fastening procedures while maintaining strong attachment forces.

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

Solution Approach 2:

The patent introduces magnetic fields as an intermediary force between the sorting bowl and sorting elements. This magnetic intermediary provides both attachment strength and automatic alignment, allowing elements to be quickly attached and detached without mechanical fasteners while ensuring precise positioning.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If sorting elements are welded or hand-formed, then attachment precision is improved, but adaptability and replacement speed worsen

Engineering Contradiction:
Improveattachment precisionVSAvoidelement replacement speed
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The magnetic attachment system replaces permanent welding and hand-forming processes, enabling sorting elements to be quickly changed by simply attaching or detaching them from the sorting bowl. This maintains precise positioning through magnetic alignment while dramatically improving adaptability for different bulk materials and sorting requirements.

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

Solution Approach 2:

The patent transforms the attachment system from a static, permanent connection (welding) to a dynamic, reversible connection (magnetic attachment). This allows the sorting elements to be easily reconfigured and replaced depending on the sorting task, providing both precision and flexibility.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple conveyors are used for different sorting processes, then sorting capability is improved, but device complexity and cost increase

Engineering Contradiction:
Improvesorting capabilityVSAvoidnumber of conveyors
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal sorting conveyor system where a single vibratory spiral conveyor can handle multiple sorting tasks by simply changing the sorting elements. The magnetic attachment system enables quick interchange of elements designed for different bulk materials and sorting requirements, eliminating the need for multiple dedicated conveyors and reducing overall system complexity.

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

AI summary

A vibrating spiral conveyor (10) is shown. The vibrating spiral conveyor (10) comprises a vibratable sorting bowl (12) which has a shoulder (18) on its inside which spirals towards the upper edge (14) of the sorting bowl (12). In addition, the vibrating spiral conveyor (10) has at least one attachment element (22) on the sorting bowl (12), wherein the sorting bowl (12) and the attachment element (22) each have at least one magnet (24). When attached to the sorting bowl (12), the magnets (24) lie opposite one another with opposite polarity. The attachment element (22) is thus detachably attached to the sorting bowl (12) via the magnets (24).
