Solution Overview

Problem

Existing building blocks do not effectively reduce radon levels in indoor environments, as radon can penetrate through cracks in concrete floors, posing health hazards and exceeding safety limits.

Innovation Solution

A building block design featuring a first block, a second block, and an insulation block with channels that extend through the insulation block, allowing radon to be collected and removed from beneath a concrete floor, thereby improving indoor air quality.

Engineering Contradictions & Design Principles

1Object-affected harmful factors

If channels are added to the building block to remove radon, then radon reduction capability is improved, but device complexity increases

Engineering Contradiction:
Improveradon levelVSAvoidbuilding block structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The building block is divided into three distinct segments: a first block, a second block, and an intermediate insulation block. The channels are specifically formed within the insulation block segment, allowing radon removal functionality to be isolated to a specific segment rather than complicating the entire building block structure. This segmentation enables the radon reduction feature to be added without fundamentally redesigning the core structural components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The intermediate insulation block serves as a mediator that hosts the channels for radon removal. Rather than integrating channels directly into the structural blocks, the insulation block acts as an intermediary carrier that provides both thermal insulation and radon venting pathways. This intermediary approach allows the radon reduction system to function independently while maintaining the integrity of the primary structural blocks.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If channels extend through the insulation block for radon removal, then radon removal efficiency is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveradon penetrationVSAvoidbuilding block production
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The channels are pre-formed within the intermediate insulation block during the insulation block's manufacturing process, before the insulation block is assembled with the first and second blocks. This preliminary action allows the channels to be created using standard insulation block manufacturing techniques, avoiding the need for complex post-assembly channel installation or modification of the structural blocks.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The channel formation process extracts material from the intermediate insulation block to create the radon removal pathways. By taking out material only from the insulation block and not from the structural blocks, the manufacturing process remains relatively simple while still achieving the desired channel functionality for radon venting.

Inventive Principle:
Principle #2Taking out (Extraction)

3Temperature

If multiple layers of building blocks are arranged for insulation, then thermal insulation performance is improved, but radon removal capability deteriorates

Engineering Contradiction:
Improvethermal insulationVSAvoidradon accumulation
Core Design Contradiction:
TemperatureVSObject-affected harmful factors

Solution Approach 1:

The intermediate insulation block is designed to perform multiple functions simultaneously: it provides thermal insulation between the first and second blocks, and it serves as the carrier for channels that remove radon. This multi-functionality ensures that adding insulation layers does not compromise radon removal capability, as each insulation block layer can independently perform both insulation and radon venting functions.

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

Solution Approach 2:

The channels extend continuously through the intermediate insulation block, ensuring uninterrupted radon removal pathways even when multiple layers of building blocks are stacked. This continuity of the channel system through the insulation layer maintains effective radon removal capability while preserving the thermal insulation performance of the multi-layer construction.

Inventive Principle:
Principle #20Continuity of useful action
