The document discusses spatial issues in modern houses due to decreasing size. It aims to reduce cleaning time and increase house capacity. The problem is defined as increasing capacity of dining, living, and bedroom areas. Tables, chairs and other furniture take up significant space. TRIZ tools are used to generate solutions, with the trimming process identifying that table and chair bases can be combined. A potential solution is proposed using inventive principles 7 and 1 to nest or segment furniture parts so areas have adjustable capacity while maintaining comfort.

1. Part 3– House spatial issues
My TRIZ competition

2. The problem statement
The Issues that have to be solve
• To reduce the time consumption from
cleaning the house
• Increase the capacity of modern houses
Size of houses decrease in
cities, thus spatial issues is
crucial in modern society

3. Benefits
If problem solved:
• Every furniture installed without losing
comfort of a house
• Have a sense of space although house is small
Impact
If problem solved:
• High ratio of population to land area’s country
can have a sense of comfort of a house

6. TRIZ tool used an Solutions
Trimming process is used for this problem

7. Other TRIZ tools
Contradiction Worsening ease of repair
Improving adaptability or versatality 7, 1, 4, 16
Combined the dining’s table base and chair base because
trimming process shown that either 1 of the bases can be
trim.
Inventive principle 7 – Nested doll
Inventive principle 1 - Segmentation
Separate part of the table to become chairs
