Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydraulic and pneumatic systems in vehicles face challenges such as space constraints in the cab, cumbersome and costly routing of air lines, and difficulty in expanding the system to accommodate additional devices, as each device requires separate connections to the air supply and activation switch.
Innovation Solution
An expandable air distribution system utilizing a modular design with removably connected base/solenoid assemblies, inlet pieces, and endcaps, featuring a connector system that allows for multiple devices to share a single air supply connection, enabling flexible expansion and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional air switches are installed in the cab for each device, then each device can be operated independently, but the switches take up too much space in the cab
Solution Approach 1:
The system segments the air distribution function into modular electromagnetic switch units that can be distributed throughout the vehicle rather than concentrated in the cab. Each switch unit handles specific devices, allowing spatial distribution of functionality and reducing cab clutter.
Solution Approach 2:
The patent introduces an intermediary air distribution system with manifold and routing infrastructure that enables remote placement of control switches away from the cab. This intermediary infrastructure mediates between the air supply and distant devices, allowing switches to be positioned optimally for space efficiency.
2Ease of operation
If air lines are routed to each switch individually, then each device can be controlled separately, but the routing becomes cumbersome and costly
Solution Approach 1:
The electromagnetic switch units are designed as universal modular components that can serve multiple devices through the shared air distribution network. Each switch unit provides the same control function for different devices, allowing standardized installation and simplified routing infrastructure that serves multiple purposes.
Solution Approach 2:
The system transitions from point-to-point air line routing to a distributed network topology with manifold connections. This dimensional change in system architecture allows multiple devices to share common air supply pathways, reducing the total number of individual routes needed while maintaining independent control capability.
3Adaptability or versatility
If the air system is expanded by adding new devices with separate connections, then device functionality is added, but the system becomes harder to expand and requires additional connections to the air supply
Solution Approach 1:
The air distribution system is segmented into modular switch units that can be independently added or removed. Each unit is a self-contained module with standardized connections, allowing incremental system expansion without requiring complex reconfiguration of the entire air supply network.
Solution Approach 2:
Multiple air distribution functions are merged into a unified modular switch unit design. By combining the switching mechanism, air inlet, and outlet connections into single integrated modules, the system allows easy expansion where new units are simply connected in series or parallel to existing infrastructure without requiring separate connection pathways for each device.
4Adaptability or versatility
If T fittings are used to chain off new connections from existing air lines, then new devices can be added, but finding space on the vehicle for the air distribution system becomes difficult
Solution Approach 1:
The system transitions from planar air line routing with T-fittings to a three-dimensional distributed network using vertical and lateral routing pathways. This allows air distribution infrastructure to utilize unused vertical spaces and complex routing geometries within the vehicle structure, finding space in dimensions that were previously unavailable for traditional horizontal T-fitting configurations.
