Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If vibration discs are used to screen or change the attitude of workpieces, then the workpieces can be arranged in an orderly manner, but violent collision and friction between workpieces will easily lead to damage

Engineering Contradiction:
Improveorderly arrangement of workpiecesVSAvoidworkpiece damage from collision and friction
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent uses a vibration disc to generate vibrational motion that facilitates the orderly arrangement of workpieces. The vibration causes workpieces to move and self-organize on the conveying platform without requiring violent collisions, thus achieving stable arrangement while minimizing damage through controlled vibrational energy.

Inventive Principle:
Principle #18Mechanical vibration

2Productivity

If non-coplanar centrifugal discs are used, then workpieces can be conveyed, but the gap between discs makes them unsuitable for screening or attitude change of smaller workpieces

Engineering Contradiction:
Improveworkpiece conveying capabilityVSAvoidsuitability for smaller workpieces
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent transitions from a three-dimensional non-coplanar centrifugal disc structure to a two-dimensional coplanar conveying platform. This dimensional simplification eliminates the gap problem between discs, allowing the platform to effectively screen and change the attitude of smaller workpieces while maintaining conveying capability through planar motion.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If traditional screening mechanisms are used, then workpieces can be screened, but the process is slow and lacks high-speed output capability

Engineering Contradiction:
Improveworkpiece screening accuracyVSAvoidoutput speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements continuous screening and conveying operations on the coplanar platform, where workpieces are continuously fed, screened, and discharged without interruption. The vibration disc maintains constant vibrational motion to ensure continuous workpiece movement and arrangement, eliminating idle time and achieving both high screening reliability and high-speed output.

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If the conveying speed is increased for high-speed output, then productivity improves, but workpiece damage from collision increases

Engineering Contradiction:
Improveoutput speedVSAvoidworkpiece damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The vibration disc provides controlled vibrational energy that enables high-speed conveying while minimizing harmful collisions. The vibration keeps workpieces in constant motion and prevents them from stacking or colliding violently during acceleration and deceleration, allowing high productivity to be achieved without increasing workpiece damage.

Inventive Principle:
Principle #18Mechanical vibration
