Solution Overview

Problem

Existing clothes treating apparatuses with heat pumps are not separable, limiting their versatility and energy efficiency, as the heat pump components are fixed within the cabinet, restricting their operational modes and energy usage.

Innovation Solution

A separable heat pump system that can be independently operated with different modes, including a drying mode when mounted on the cabinet and a dehumidification mode when separated, allowing for controlled temperature and energy usage optimization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the heat pump components are assembled into the cabinet in a fixed manner, then the heat pump structure is stable and integrated, but the heat pump cannot be separated to be independently operable

Engineering Contradiction:
Improveoperational versatilityVSAvoidstructural integration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heat pump system is divided into separable components: the heat pump unit (including compressor, evaporator, condenser) can be detached from the cabinet while maintaining functional integrity. This segmentation enables the heat pump to operate independently or be reconfigured for different uses.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mounting structure transitions from a fixed static state to a dynamic state where the heat pump can be easily attached and detached. The design incorporates removable connections and flexible power supply options that allow the system to adapt between integrated and independent operational modes.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the heat pump is mounted on the cabinet, then drying mode can be operated for clothes treatment, but energy efficiency is reduced compared to independent dehumidification operation

Engineering Contradiction:
Improveoperation mode flexibilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system changes operational parameters based on mounting state. When mounted on the cabinet, the heat pump operates in drying mode with higher temperature and longer cycles optimized for clothes treatment. When separated, it switches to dehumidification mode with adjusted temperature and timing parameters optimized for energy efficiency in standalone operation.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The heat pump controller automatically detects the operational context (mounted or separated) and self-adjusts the operating parameters without user intervention. The system serves itself by selecting the appropriate mode (drying or dehumidification) based on its physical state, optimizing energy usage for each scenario.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the heat pump is separated from the cabinet, then independent operation is enabled, but the power supply connection becomes more complex

Engineering Contradiction:
Improveindependent operabilityVSAvoidpower supply configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The power supply system is designed with universal compatibility: the heat pump can draw power from the cabinet's internal power supply when mounted, or connect to external power sources when separated. The controller and electrical connections are configured to handle multiple power supply scenarios, making the system adaptable to different installation environments without requiring complex specialized wiring for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)
