Ceiling mounted evaporator blower with swing up hinged installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling-mounted air conditioning units require significant retrofitting or removal of ceiling joists for installation, making it costly and impractical to install in existing buildings without modifying the structure.
Innovation Solution
An air conditioning system with a chassis designed to fit between ceiling joists, featuring a pivotally coupled mounting flange and diffuser, allowing the chassis to pivot between positions below and above the ceiling, enabling easy installation and maintenance without altering the joist configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional ceiling mounted air conditioning units are installed, then cooling function is provided, but the unit width exceeds the distance between ceiling joists requiring joist removal or relocation
Solution Approach 1:
The mounting flange is pivotally coupled to the chassis, enabling the chassis to swing between a first position below the ceiling and a second position above the ceiling. This dynamic movement allows the chassis to be maneuvered into the confined space between existing joists during installation, resolving the contradiction between chassis width and joist spacing compatibility
Solution Approach 2:
The invention transitions the installation problem from a two-dimensional width constraint to a three-dimensional spatial solution by utilizing vertical movement through pivotal coupling. The chassis moves from below the ceiling to above the ceiling through rotation, effectively using the vertical dimension to overcome the horizontal width limitation imposed by joist spacing
2Adaptability or versatility
If ceiling joists are removed or relocated to accommodate wider units, then larger air conditioning units can be installed, but installation cost increases significantly and building codes must be maintained
Solution Approach 1:
The pivotal coupling mechanism allows the chassis to dynamically reposition itself during installation, swinging from below to above the ceiling. This eliminates the need for static structural modifications like joist removal, thereby reducing installation cost and complexity while maintaining adaptability to different joist spacings
Solution Approach 2:
The mounting flange with pivotal coupling serves multiple functions: it allows the chassis to be installed in existing ceilings without joist modification, provides secure mounting when positioned above the ceiling, and enables easy removal and repositioning. This multi-functionality achieves unit size flexibility without increasing installation cost or complexity
3Reliability
If the chassis is positioned above the ceiling between joists, then proper air flow pathway is established, but the chassis cannot be easily removed for maintenance
Solution Approach 1:
The pivotal coupling between the mounting flange and chassis enables the chassis to swing between positions above and below the ceiling. When installation is complete, the chassis rests in the second position above the ceiling establishing the proper air flow pathway. For maintenance, the chassis can be swung back below the ceiling and removed, providing ease of repair while maintaining reliable air flow configuration during operation

AI summary
An evaporator blower for air conditioning system that can be installed into a ceiling between existing joists. The system has a chassis dimensioned to fit between the pair of joists forms an air flow pathway through which air may be cooled by an evaporator housed in the chassis. A mounting flange is pivotally coupled to the chassis and has an opening through which the chassis can pivot between a first position below the mounting flange, and thus the ceiling, to a second position above the flange, so that the chassis is above the ceiling and between the pair of joists. A diffuser is attached to the mounting flange and provides supply and return air grilles that are in fluid communication with the air flow pathway of the chassis.
