Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing bulk material switches are used to connect multiple conveyor lines, then the switching function is achieved, but the design complexity and manufacturing difficulty increase

Engineering Contradiction:
Improveswitching functionVSAvoiddesign complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The actuator is divided into multiple separate parts (first part, second part, third part) that can be manufactured independently and then assembled. The connecting channel is formed by combining recesses from different parts, avoiding the need to manufacture a complex single-piece actuator with undercuts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The recesses in the actuator parts are designed to nest together when assembled, forming the complete connecting channel. The recesses interlock like nested dolls, creating the functional channel structure through the combination of simpler individual components.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If existing bulk material switches are used to connect multiple conveyor lines, then the switching function is achieved, but the manufacturing difficulty increases

Engineering Contradiction:
Improveswitching functionVSAvoidmanufacturing difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The actuator is divided into multiple separate parts (first part, second part, third part) that can be manufactured independently using standard manufacturing processes without requiring complex undercut removal or specialized tooling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of creating the connecting channel as a solid feature that requires undercut removal, the channel is created as a negative space formed by the combination of recesses from multiple parts. This inverts the manufacturing approach from adding material to removing it.

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

3Device complexity

If a single-piece actuator design is used, then the structure is simpler, but manufacturing becomes more difficult due to undercuts

Engineering Contradiction:
Improvestructural simplicityVSAvoidmanufacturing difficulty
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The actuator is segmented into multiple parts that can be manufactured without undercuts. Each part has a simpler geometry that is easier to manufacture, and the segments are assembled to form the complete actuator with the connecting channel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting channel is formed by the combination of recesses from multiple parts rather than being a single continuous feature. This partial formation approach allows each part to be manufactured independently without requiring complex undercut geometry.

Inventive Principle:
Principle #16Partial or excessive action
