Solution Overview

Problem

Existing condenser units in air conditioning systems are difficult to access for service and repair, leading to increased time and cost for maintenance.

Innovation Solution

The condenser unit features hinged panels for easy access, conveniently located service valves, a sliding compressor plate with ball bearing rollers, and quick release fittings on internal hoses, along with LED illumination for status indication and secure locking mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If components are contained within a housing with four sides, a floor and a top, then the condenser unit is protected and structurally sound, but access to components for service and repair becomes difficult

Engineering Contradiction:
Improvestructural integrityVSAvoidaccess to components
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The housing is divided into multiple removable panels (front panel, side panels, top panel) that can be independently removed to provide access to internal components. This segmentation allows service personnel to access specific components without removing the entire housing, thus maintaining structural integrity while improving accessibility for maintenance.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the compressor is fixed in position within the housing, then the unit is stable, but service and replacement of the compressor becomes time-consuming and difficult

Engineering Contradiction:
Improvecompressor positioningVSAvoidcompressor replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The compressor is mounted on a sliding plate that can be moved horizontally along guide rails within the housing. This dynamic mounting system allows the compressor to be easily accessed by sliding it outward through an opening in the front panel, enabling quick service and replacement while maintaining stable positioning during normal operation.

Inventive Principle:
Principle #15Dynamics

3Reliability

If service valves are located inside the housing, then they are protected, but access for servicing requires opening the housing and increases maintenance time

Engineering Contradiction:
Improveprotection of service valvesVSAvoidmaintenance time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The service valves are extracted from the internal housing structure and relocated to the external surface of the housing. This allows service personnel to access and service the valves directly from the outside without needing to open the housing panels, significantly reducing maintenance time while keeping the valves protected within the housing structure.

Inventive Principle:
Principle #2Taking out (Extraction)

4Reliability

If internal hoses use traditional connection fittings, then they are secure, but replacement requires special tools and increases service complexity

Engineering Contradiction:
Improvehose connection securityVSAvoidservice tool requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The hose connections use quick-release fittings that can be operated by hand without requiring special tools. The fittings include a release mechanism that allows service personnel to quickly disconnect and reconnect hoses during maintenance, simplifying the service process while maintaining secure connections during normal operation.

Inventive Principle:
Principle #25Self-service

AI summary

A condenser unit for an air conditioning system includes LED illumination that changes color to indicate status of operation. A lid, front and side panels of the condenser unit are hinged and can be easily opened to allow full access to clean the condenser coil and service the unit. Service valves for liquid and suction lines are conveniently located on the back exterior of the unit for easy access. A fan bracket allows for easy removal and replacement of the fan motor. A sliding compressor plate, aided by ball bearing rollers, enables easy and unobstructed access to the compressor for service and replacement. Internal hoses have quick release fittings that can be released by hand without the need for special tools.
