Solution Overview

Problem

Existing air conditioning systems in public transport vehicles face challenges in uniformly distributing conditioned air without increasing costs or reducing available space, and existing conduits complicate maintenance and structure.

Innovation Solution

A voussoir assembly and distribution system with arc-shaped elements and a feeding unit that partitions airflow between front and rear vehicle portions, using a curved conduit design and hinge connections for efficient airflow distribution and easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If multiple conduits are provided within voussoirs or ceiling assembly to distribute conditioned air, then uniform air distribution is achieved, but manufacturing assembly time and costs increase

Engineering Contradiction:
Improveuniform air distributionVSAvoidmanufacturing assembly time and costs
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent merges multiple separate conduits into a single integrated conduit structure. The voussoir assembly incorporates multiple air distribution outlets within one unified conduit body, eliminating the need for multiple separate conduits while maintaining uniform air distribution across different zones of the vehicle interior.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single conduit structure performs multiple functions simultaneously: it distributes conditioned air to multiple different zones, provides structural support, and serves as a mounting platform for various outlets. This multi-functionality reduces the overall number of components needed and simplifies the assembly process.

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

2Area of stationary object

If multiple conduits are provided within voussoirs or ceiling assembly to distribute conditioned air, then air distribution coverage is improved, but device complexity increases

Engineering Contradiction:
Improveair distribution coverageVSAvoidstructure complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The conduit is segmented into multiple functional zones with different outlets positioned at various locations and orientations. Each segment serves a specific zone of the vehicle interior, allowing comprehensive coverage while maintaining a unified structural design that reduces overall complexity.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If multiple conduits are provided within voussoirs or ceiling assembly to distribute conditioned air, then air distribution uniformity is improved, but maintenance inspection time increases

Engineering Contradiction:
Improveair distribution uniformityVSAvoidmaintenance inspection time
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

By combining multiple air distribution functions into a single accessible conduit structure, maintenance personnel can inspect and service all outlets and internal components through one main access point, significantly reducing maintenance inspection time compared to accessing multiple separate conduits.

Inventive Principle:
Principle #5Merging (Combining)

4Manufacturing precision

If multiple conduits are provided within voussoirs or ceiling assembly to distribute conditioned air, then air distribution effectiveness is improved, but free available space within inner space is reduced

Engineering Contradiction:
Improveair distribution effectivenessVSAvoidfree available space
Core Design Contradiction:
Manufacturing precisionVSVolume of moving object

Solution Approach 1:

The integration of multiple air distribution outlets into a single conduit structure reduces the total volume occupied by air distribution infrastructure. This consolidated design minimizes space requirements while maintaining effective air distribution to all necessary zones of the vehicle interior.

Inventive Principle:
Principle #5Merging (Combining)
