Mobile Climate Control Assembly With Fixed-Housing Airflow Steering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing climate control devices for mobile or remote environments are inefficient and impractical, as they often require rotation of fan housings, which leads to mechanical failures, high costs, and limited control over air directional flow.
Innovation Solution
A mobile climate control assembly with computer-controlled fan blower-wheel assemblies that generate air velocity gradients without rotating the fan housing, using two crossflow or tangential fans angled with respect to each other, and an electronic controller to independently control airflow across a wide angular range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rotatable fan housing is used to control directional air flow, then air flow direction control is achieved, but device complexity and mechanical failure risk increase due to motors and bearings
Solution Approach 1:
The patent replaces the mechanical rotation system (motors and bearings that rotate the entire fan housing) with a fixed housing design that uses electronically controlled fan blade assemblies. The directional control is achieved through electronic control of multiple fan units rather than mechanical rotation, eliminating the need for complex rotating mechanical components while maintaining adaptability in air flow direction.
Solution Approach 2:
The patent divides the fan system into multiple independent fan blower-wheel assemblies (first and second fans) that can be independently controlled. Each fan assembly can be directed at different angles, allowing the system to achieve variable air flow directions without rotating the entire housing. This segmentation enables directional control through electronic means rather than mechanical rotation.
2Adaptability or versatility
If rotatable fan housing is used to distribute air flow, then air distribution is achieved, but reliability decreases due to more moving parts prone to failure
Solution Approach 1:
The patent eliminates the mechanical rotation system (motors and bearings) by using a fixed housing with electronically controlled fan assemblies. The air flow distribution is achieved through electronic control of multiple fan units rather than mechanical rotation, removing the moving parts that are prone to failure and thereby improving reliability while maintaining air flow distribution capability.
3Adaptability or versatility
If traditional fan housing rotation is used, then air flow control is achieved, but manufacturing cost increases due to additional components
Solution Approach 1:
The patent replaces the expensive mechanical rotation system with a simpler fixed housing design that uses electronic control of fan assemblies. This substitution eliminates the need for motors and bearings, reducing component costs and simplifying manufacturing while maintaining the capability for directional air flow control through electronic means.
Solution Approach 2:
The patent uses multiple independently controllable fan assemblies within a fixed housing. This segmentation allows the system to achieve directional control without the expensive mechanical rotation mechanism, as each fan can be electronically directed at different angles, reducing overall manufacturing costs while maintaining adaptability.

Function Achieved in This Case
This solution provides efficient and effective climate control by generating oscillated airflow patterns up to 160° without the need for rotating parts, reducing mechanical failures and costs, and allowing precise control over ambient air flow.
Implementation Method 1
a first fan blower-wheel assembly and a second fan blower assembly each respectively having a wheel member and an air deflector wall. The wheel member is disposed within the housing cavity and with a plurality of wheel blades disposed circumferentially around the wheel member and operably configured to rotate 360° around an axis of rotation
Implementation Method 2
The air deflector wall is coupled to the housing and surrounding a partial circumference of the wheel member and having a front end portion disposed proximal to the front face of the housing and configured to direct air generated from the wheel member outwardly away from the front face of the housing

AI summary
A mobile climate control assembly that includes a portable housing with a first fan blower-wheel assembly and a second fan blower assembly each respectively having a wheel blade member, partially surrounded by an air deflector wall, disposed within a housing cavity and operably configured to rotate 360° around an axis of rotation parallel and non-co-planar with respect to one another. The assembly also includes a fan motor operably coupled to the wheel blade members and an electronic controller electronically and communicatively coupled to the fan motor and operably configured to independently and selectively control rotation of the wheel member of each of the first and second fan blower-wheel assemblies to generate an ambient air velocity gradient along at least an approximate 90° angular traverse path from the front face and without rotation of the portable housing.
