Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a rotary cutting mechanism is used to grind dry ice blocks into particles, then dry ice particles can be produced for cleaning workpieces, but the amount of dry ice particles delivered is not adjustable

Engineering Contradiction:
Improveamount of dry ice particles deliveredVSAvoidadjustability of particle delivery
Core Design Contradiction:
Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by making the receiving tray rotatable around the rotary cutting mechanism. The tray can be rotated to different angles to adjust the receiving amount of dry ice particles. This dynamic adjustment capability allows the system to adapt to different cleaning requirements while maintaining continuous operation of the cutting mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a new dimension of adjustment by rotating the receiving tray around the cutting mechanism in a horizontal plane. This angular dimension provides an additional degree of freedom for controlling particle delivery quantity, transforming a static receiving system into a dynamically adjustable one without modifying the cutting process itself.

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

2Force

If dry ice blocks are ground into small particles using a cutting mechanism, then particle spray can be generated for cleaning, but the impact force on workpieces is insufficient

Engineering Contradiction:
Improveimpact force on workpiecesVSAvoidcleaning efficiency
Core Design Contradiction:
ForceVSProductivity

Solution Approach 1:

The patent applies dynamics by implementing a rotatable receiving tray that can be positioned at different angles relative to the accelerating air pump. This allows optimization of the particle delivery angle and position to maximize impact force on workpieces while maintaining efficient cleaning productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses preliminary action by pre-positioning and pre-adjusting the receiving tray to optimal angles before particle delivery begins. The tray is prepared in advance at the correct orientation to ensure maximum impact force when particles are accelerated toward the workpiece, improving cleaning efficiency without requiring real-time adjustments during operation.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If a receiving tray is used to collect and transport dry ice particles, then particles can be delivered to workpieces, but the transport path is not sealed causing particle loss

Engineering Contradiction:
Improvedry ice particle deliveryVSAvoidparticle loss during transport
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent applies this principle by implementing a sealed transport path using flexible sealing structures between the receiving tray and the accelerating air pump. The sealing prevents dry ice particles from escaping during transport while allowing the tray to rotate, thus reducing particle loss without restricting the adjustable delivery capability.

Inventive Principle:
Principle #30Flexible shells and thin films

4Adaptability or versatility

If the receiving tray is rotated to adjust particle delivery amount, then adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveadjustability of particle deliveryVSAvoidcomplexity of linkage mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies merging by combining the receiving tray rotation mechanism with the existing rotary cutting mechanism into a single integrated linkage system. Both components are driven by a common driving device through a reversing linkage, reducing the number of independent motors and control systems needed, thus lowering overall device complexity while maintaining adjustability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universality by designing a multi-functional linkage device that simultaneously performs multiple tasks: it transmits power from the driving device to both the rotary cutting mechanism and the receiving tray, enables angular adjustment of the tray, and maintains synchronized operation. This single mechanism serves multiple functions, avoiding the need for separate complex control systems.

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