Solution Overview

Problem

Conventional condensate collection tanks in air conditioning systems face challenges due to limited capacity, maintenance accessibility, and aesthetic issues when positioned under units, requiring significant clearance for servicing and leading to increased installation costs and unsightly installations.

Innovation Solution

A condensate collection tank design allowing the lid and body to be separated for maintenance without disturbing sensors, with a resilient clip system and a protective barrier for the sensor, enabling closer mounting to the air conditioning unit and reducing false readings, along with a secondary sensor for failsafe operation and improved cable management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the condensate collection tank is mounted underneath the air conditioning unit to achieve compact installation and aesthetic appearance, then the installation occupies less wall area and looks more appealing, but significant clearance (at least 35mm) must be left for maintenance access, increasing installation complexity and costs

Engineering Contradiction:
Improvewall area occupiedVSAvoidmaintenance accessibility
Core Design Contradiction:
Area of stationary objectVSEase of repair

Solution Approach 1:

The tank is divided into two separable parts: a lid portion and a body portion. The lid can be detached from the body to provide access to the tank interior for maintenance activities such as cleaning and sensor inspection, eliminating the need for significant clearance around the entire tank while maintaining compact installation

Inventive Principle:
Principle #1Segmentation

2Reliability

If the sensor is mounted on the lid to maintain position during assembly, then the sensor remains stable during operation, but the sensor is vulnerable to damage during assembly and disassembly of the lid and body

Engineering Contradiction:
Improvesensor stabilityVSAvoidsensor damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A barrier structure is provided on the lid that extends to protect the sensor before any assembly or disassembly operations occur. This preliminary protective measure shields the sensor from potential damage during the assembly and disassembly processes while maintaining sensor stability during operation

Inventive Principle:
Principle #10Preliminary action

3Use of energy by moving object

If the tank capacity is increased to store sufficient condensate and reduce pump running time, then energy consumption decreases, but the tank requires more space and cannot be positioned close to the air conditioning unit

Engineering Contradiction:
Improvepump energy consumptionVSAvoidtank volume
Core Design Contradiction:
Use of energy by moving objectVSVolume of moving object

Solution Approach 1:

The separable lid and body design allows the tank to be configured in different orientations and positions. The tank can be mounted vertically or at angles to maximize capacity within limited space, enabling sufficient condensate storage while maintaining compact installation close to the air conditioning unit

Inventive Principle:
Principle #1Segmentation

Methodology Applied
Scientific EffectPhysical barrier protection:

Implementation Method 3

a sensor provided in the lid to detect when the liquid level in the tank indicates that the pump should be activated

Methodology Applied
Scientific EffectSensor detection:

Implementation Method 4

a condensate removal pump is typically employed, in combination with a condensate collection tank, to convey the water through a discharge tube

Methodology Applied
Scientific EffectPump mechanical force: Pump

Implementation Method 5

AI summary

A condensate collection tank (1) for an air conditioning system is provided. The tank (1) comprises a body (20) for storing condensate liquid, a lid (10) releasably connectable to the body (20) to form the tank (1) and a mounting bracket (112) for fixing the lid (10) to a mounting surface. The tank (1) further includes an inlet port {50, 90) for condensate liquid from the air conditioning system, an outlet port {40, 80) for condensate liquid from the tank (1), a sensor (104) for determining whether an amount of condensate liquid in the tank (1) exceeds a threshold value, and a controller for controlling removal of the condensate liquid from the tank {1) via the outlet port (40, 80) when the sensor (104) determines that the threshold value has been exceeded.
