Heating Valve Control With Mechanical Position Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating unit valve control systems are limited by nonprogrammable thermostatic valves that require manual temperature adjustments, lack central control capabilities, and generate noise and vibrations due to mechanical transmission systems, while also being costly and energy-inefficient.
Innovation Solution
A cordless valve control device featuring a radio transmitter and receiver, a two-axial transmission system with a rotary collar indicator, and an electric engine, which allows for central temperature control, reduces noise and vibrations through flexible materials, and minimizes production costs by using a simple mechanical indicator instead of LCD displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electronic LCD display is used to show valve position, then measurement precision is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent uses a mechanical collar that rotates to indicate valve position, creating a simple physical copy of the valve's angular position. This mechanical indicator replaces complex electronic LCD displays while maintaining the ability to show valve position information clearly through the transparent window.
Solution Approach 2:
The patent replaces electronic measurement and display systems with a purely mechanical indication system. The collar rotates mechanically with the valve and displays position through a transparent window, eliminating the need for electronic sensors, processors, and displays while maintaining measurement precision.
2Ease of manufacture
If mechanical transmission system is used for valve control, then ease of manufacture is improved, but noise and vibrations increase
Solution Approach 1:
The patent uses a flexible membrane diaphragm as part of the transmission system. This flexible element replaces rigid mechanical linkages that generate noise and vibrations, while maintaining the ability to transmit control force from the actuator to the valve. The flexible membrane absorbs vibrations and operates silently.
Solution Approach 2:
The patent employs composite construction combining flexible membrane material with rigid housing and components. This allows the system to benefit from both the quiet, vibration-absorbing properties of flexible materials and the structural integrity of rigid components, resolving the contradiction between ease of manufacture and noise reduction.
3Ease of operation
If cordless system with batteries is used, then ease of operation is improved, but use of energy increases
Solution Approach 1:
The patent uses a mechanical clockwork winding mechanism that converts periodic manual winding motion into stored mechanical energy. This replaces continuous battery power consumption with periodic energy input from the user, significantly reducing ongoing energy requirements while maintaining cordless operation and central control capabilities.
Solution Approach 2:
The system allows the user to recharge the mechanical energy storage mechanism through manual winding, making the device self-sufficient without requiring external battery replacement or electrical connections. The user serves both as operator and energy source, eliminating the energy consumption issue associated with batteries.
