Solution Overview

Problem

Existing adjusting drums for product-dispatching machines require axial traction along the spiral rotation axis, making adjustments difficult, slow, and prone to damage, especially when products are already placed, leading to inefficiencies and maintenance challenges.

Innovation Solution

An adjusting drum design that eliminates the need for axial traction by using a bayonet-type connection clamp and radial ratchet gear means to angularly orient the spiral, allowing step-wise rotation and easy removal, with coupling mechanisms for spiral exchange, and optional mechanical clamping for counter-rotating spirals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If axial traction is applied to adjust spiral position using elastic elements, then spiral orientation can be changed, but the operation becomes difficult, slow and prone to damage

Engineering Contradiction:
Improveease of spiral adjustmentVSAvoidrisk of elastic element breakage
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent removes the elastic elements entirely from the adjusting drum mechanism, replacing them with a bayonet-type connection system. This extraction eliminates the reliability issues associated with elastic element fatigue and breakage while simplifying the adjustment operation to a straightforward rotational motion without requiring axial traction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using axial traction to separate plates and enable rotation, the invention inverts the mechanism by using rotational motion directly to engage or disengage the bayonet connection. The spiral is adjusted by rotating the adjusting drum, which directly rotates the spiral without needing to pull it axially, thus inverting the traditional adjustment approach.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If axial traction is used to adjust spiral orientation, then position can be changed, but products may fall by gravity requiring reloading

Engineering Contradiction:
Improveease of spiral adjustmentVSAvoidtime for product reloading
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent inverts the adjustment mechanism from axial traction to direct rotational adjustment. By rotating the adjusting drum, the spiral orientation is changed without axial movement, thereby preventing products from falling due to gravity and eliminating the need for reloading operations.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If elastic elements are used for plate separation, then spiral rotation is enabled, but the structure becomes more complex and maintenance difficult

Engineering Contradiction:
Improveadjustability of spiral positionVSAvoidcomplexity of adjusting drum structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts and removes the elastic elements from the adjusting drum, replacing the complex plate separation mechanism with a simpler bayonet-type connection system. This reduces device complexity while maintaining the essential adjustability function through direct rotational engagement.

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If axial traction is applied to move plates apart, then spiral orientation can be adjusted, but the operation becomes fatiguing and slow

Engineering Contradiction:
Improveprecision of spiral orientationVSAvoidease of spiral adjustment
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent inverts the adjustment approach by eliminating axial traction entirely. The bayonet-type connection allows precise spiral orientation to be achieved through simple rotational motion of the adjusting drum, making the operation both precise and easy without requiring fatiguing axial forces.

Inventive Principle:
Principle #13The other way round (Inversion)
