45° Door Catch :

Redesign an Ignored Object

Project Background

We all know that design focuses on solving problems and making our lives better. However, good design usually means high cost, which people suffering from poverty cannot afford.  So our group tried to figure out how to redesign with the limited cost for poor people.

On-site Research

 

As a result, our group set Chinese villagers as our target user and redesign one object in their lives. For better understanding their living environment, we planned a field trip to Jiangxi Province. Through the 1-week village-life and the interviews with local villagers, we summarized lifestyle of the Chinese villagers and collected several objects they use in daily lives. Then we listed merits and drawbacks of each object and considered how can redesign one of them based on utility and get rid of high production cost meanwhile.

Problem Finding

 

After summarizing their living environment, we found the design opportunities from the traditional door catch and started focusing on redesigning it with two concerns.

· Frequent bumps make door catch

  bent and deformed, decreasing its 

  service life.

 

· Traditional door catch is movable, 

  the user gets scraped and hurt easily.

Design Outcome

Design Description

 

Traditional door catch is still used widely in Chinese villages. When not latched closed, the front part of door catch is movable and can be bumped or scraped easily, deforming the metal and making it unusable. The axis of rotation on the 45° Door catch has been refined to 45°, so the movable part of the catch naturally hangs down due to gravity which prevents it from moving freely and getting caught or bent.  As a result, service life is extended, and safety is ensured.
