Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a traditional gas turbine process uses a large compressor operated by rotational expanders, then gas compression is achieved, but energy efficiency deteriorates and device complexity increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The compression process is divided into multiple stages with intermediate cooling. The fluid distributing apparatus segments the gas flow into multiple streams that can be processed independently through different channels, allowing for more efficient compression with smaller compressors rather than one large compressor

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A fluid distributor apparatus acts as an intermediary device between the compressor and the system. This apparatus with its rotating part and multiple channels distributes compressed gas to different outlets, enabling efficient compression without requiring the compressor to directly interface with all system components

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a large compressor is used to compress gas, then compression capacity is improved, but device complexity and cost increase

Engineering Contradiction:
Improvecompression capacityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fluid distributing apparatus divides the compression task across multiple smaller compression streams. The rotating part with multiple inlet and outlet channels allows several smaller compressors to work in parallel, achieving the same total compression capacity as one large compressor but with reduced complexity and cost

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotating part of the fluid distributing apparatus dynamically redirects gas flows between different inlet and outlet channels. This dynamic distribution allows the system to efficiently manage multiple compression streams and adapt to varying demand without requiring oversized compression equipment

Inventive Principle:
Principle #15Dynamics

3Loss of energy

If rotational expanders are coupled to compressors, then energy utilization is achieved, but energy efficiency deteriorates due to energy being used for compression rather than power generation

Engineering Contradiction:
Improveenergy utilizationVSAvoidenergy efficiency
Core Design Contradiction:
Loss of energyVSUse of energy by moving object

Solution Approach 1:

The invention extracts the compression function from the expander-compressor coupled system. By using separate compression equipment and a fluid distributing apparatus to manage the compressed gas, the system allows expanders to focus solely on power generation while compression is handled independently, eliminating the energy trade-off

Inventive Principle:
Principle #2Taking out (Extraction)
