Solution Overview

Problem

Radiators with classic thermostatic control systems cannot be used for cooling, as the thermostat head shuts off the valve when ambient temperature exceeds the set cooler temperature, preventing cold water flow.

Innovation Solution

An adapter is mounted between the radiator valve and thermostat head, featuring a transmission valve that can be rotated between control and locked positions, allowing the thermostat head's control to be transmitted to the valve for heating while locking the valve open for cooling, thus disabling the thermostat head's influence during cooling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the thermostat head is used to control the radiator valve for maintaining a set temperature, then the thermostatic control function is improved, but the radiator cannot be used for cooling because the thermostat head shuts off the valve when ambient temperature exceeds the set cooler temperature

Engineering Contradiction:
Improveradiator functionalityVSAvoidcooling operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The transmission valve is designed to be rotatable between different positions (heating position and cooling position), allowing the system to dynamically switch between heating and cooling modes. This rotational movement changes the mechanical connection state between the thermostat head and radiator valve, enabling the radiator to adapt to different operational requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The adapter is introduced as a separate intermediary component between the thermostat head and radiator valve. This extracted element provides the locking mechanism that disconnects the thermostat head's control influence during cooling mode, allowing the radiator to be used for cooling without being constrained by the thermostat head's temperature control logic.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the transmission valve is made rotatable between control and locked positions, then the adaptability for both heating and cooling is improved, but the device complexity increases due to the additional locking mechanism

Engineering Contradiction:
Improveheating and cooling capabilityVSAvoidadapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter serves multiple functions: it connects the thermostat head to the radiator valve, transmits the thermostatic control signal during heating mode, and locks the valve in open position during cooling mode. By integrating these multiple functions into a single component, the overall device complexity is minimized while achieving both heating and cooling capabilities.

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

Solution Approach 2:

The transmission valve is nested within the adapter body, with the locking mechanism integrated into the same component. The pegs of the transmission valve interact with grooves in the adapter, creating a compact nested structure that achieves the locking function without requiring separate external mechanisms.

Inventive Principle:
Principle #7Nested doll (Nesting)
