Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hydraulic systems are used for overturning containers and managing vertical feet, then the waste separation unit can be transported and emptied, but the device becomes structurally complicated and heavy

Engineering Contradiction:
Improvetransport and emptying capabilityVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent removes the complex hydraulic system from the waste separation unit, extracting only the essential function of mechanical tipping. The container is designed to tip forward using its own weight and a simple pivot mechanism, eliminating hydraulic cylinders, fluid lines, and control systems while maintaining transport and emptying capabilities

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The container is designed to tip and empty itself through a simple pivot mechanism at the front. The weight of the container and its contents provides the force needed for tipping, eliminating the need for external hydraulic assistance. The container serves its own emptying function without complex external systems

Inventive Principle:
Principle #25Self-service

2Productivity

If hydraulic components are installed on the waste separation unit, then containers can be emptied, but the risk of oil leakage increases

Engineering Contradiction:
Improveemptying capabilityVSAvoidoil leakage risk
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the hydraulic mechanical system with a pure mechanical tipping mechanism. The container pivots on a fixed axis at the front, using gravity and leverage to achieve emptying. This substitution eliminates all hydraulic components (cylinders, fluid, seals, lines) that could leak, while maintaining effective container emptying capability

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

3Device complexity

If manual gate opening is required, then the device can be simpler, but the operation becomes less efficient

Engineering Contradiction:
Improvedevice simplicityVSAvoidemptying efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The patent combines the container tipping function with the gate opening function into a single integrated action. As the container tips forward on its pivot mechanism, the rear wall naturally opens and the contents are discharged. This merging of functions eliminates separate manual gate operation while maintaining device simplicity, achieving both efficiency and simplicity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A device for separately collecting waste comprises at least two containers (2) for separately inserting waste; a base frame (3) bearing the containers (2); a tipping mechanism (15) that comprises a shaft (16) that is angularly rotatable along a respective longitudinal axis of rotation (16a) and rotatably supported by the base frame (3), and a selective connecting system (17) associated with each container to connect a respective container (2) rotatably engaged about this shaft (16) to the shaft (16), and to enable mechanical transmission of the rotational movement from the shaft (16) to the container (2) to cause it to tip around the longitudinal axis of rotation (16a) during the emptying stage.
