Solution Overview

Problem

Existing buffer storage systems in heating and cooling systems fail to achieve optimal temperature stratification, leading to inefficiencies in heat transfer and requiring larger volumes of heat transfer fluid to reach desired temperatures.

Innovation Solution

A collector and distributor system with an integrated buffer chamber, where the buffer chamber communicates with adjacent connection chambers via gap spaces between intermediate walls, preventing direct connections for heat transfer fluid introduction or removal, allowing for efficient loading and unloading in layers and minimizing disturbances in heat transfer fluid stratification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If buffer storage systems use direct connections for heat transfer fluid introduction and removal, then heat transfer efficiency is improved, but temperature stratification is disturbed

Engineering Contradiction:
Improveheat transfer efficiencyVSAvoidtemperature stratification
Core Design Contradiction:
Use of energy by moving objectVSStability of the object's composition

Solution Approach 1:

The patent introduces an intermediate buffer chamber that mediates between the connection chambers and the heat transfer fluid flow. This buffer chamber allows heat transfer fluid to be introduced and removed without directly disturbing the stratified temperature layers, as the fluid mixes in the buffer chamber before entering the connection chambers. The intermediate buffer chamber thus resolves the contradiction by enabling heat transfer while protecting temperature stratification.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the internal structure into distinct functional zones: buffer chambers for mixing and connection chambers for distributed temperature levels. This segmentation allows the system to handle heat transfer fluid flow separately from the stratified temperature storage, enabling efficient heat transfer through multiple connection chambers while maintaining stable temperature stratification in the buffer chambers.

Inventive Principle:
Principle #1Segmentation

2Productivity

If buffer storage systems aim for optimal temperature stratification, then energy storage efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveenergy storage efficiencyVSAvoidsystem structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent achieves multi-functionality by having the buffer chambers serve both as mixing zones for incoming heat transfer fluid and as storage zones for stratified temperature layers. The connection chambers simultaneously provide distributed temperature levels for multiple consumers and facilitate heat transfer. This universal design improves energy storage efficiency without proportionally increasing system complexity.

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

Solution Approach 2:

The patent employs a nested structure where buffer chambers are positioned between connection chambers, creating a hierarchical arrangement. The buffer chambers are nested within the overall tank structure, and connection chambers are arranged around them. This nested doll approach allows efficient temperature stratification and heat transfer while maintaining a compact and relatively simple overall system structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Temperature

If buffer storage systems use larger volumes of heat transfer fluid, then desired temperatures are achieved, but system inertia increases

Engineering Contradiction:
Improvedesired temperature achievementVSAvoidsystem inertia
Core Design Contradiction:
TemperatureVSDuration of action of moving object

Solution Approach 1:

The patent applies local quality by providing different temperature levels at different locations (connection chambers) rather than requiring uniform temperature throughout a large volume. Each connection chamber maintains a specific temperature level suitable for its connected consumers, allowing the system to achieve desired temperatures for multiple consumers simultaneously with smaller overall fluid volume, thus reducing system inertia while meeting temperature requirements.

Inventive Principle:
Principle #3Local quality
