Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate processes are used for height and angle adjustment of materials, then the adjustment can be performed independently, but the structure becomes complex and production efficiency is low

Engineering Contradiction:
Improveindependent adjustment capabilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines height adjustment and angle adjustment functions into a single integrated mechanism. The suction shaft assembly allows both vertical movement (height adjustment) and rotational movement (angle adjustment) to be performed through a unified structural design, eliminating the need for separate independent adjustment mechanisms and thereby reducing overall structural complexity while maintaining full adjustment capabilities

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If separate processes are used for height and angle adjustment of materials, then the adjustment can be performed independently, but production efficiency is low

Engineering Contradiction:
Improveindependent adjustment capabilityVSAvoidproduction efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

By merging height and angle adjustment into one integrated process, the patent enables simultaneous or sequential adjustment of both parameters without requiring separate operational steps. This unified approach reduces total adjustment time and improves production efficiency while preserving the ability to independently control both height and angle through the same mechanism

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If rolling contact is used between limit members, then friction is reduced and rotational sensitivity is improved, but the structure becomes more complex

Engineering Contradiction:
Improveangle adjustment precisionVSAvoidlimit member structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent introduces rolling elements (such as rollers or balls) as intermediary components between the limit members. These rolling elements mediate the contact between moving and stationary parts, converting sliding friction into rolling friction. This reduces friction and improves rotational sensitivity and angle adjustment precision, while the added complexity is localized to the rolling elements themselves rather than the entire structure

Inventive Principle:
Principle #24Intermediary (Mediator)
