The Challenge

LG Harris, a leading decorating product manufacturer, faced a long-standing issue: roller slippage during painting. This common problem caused inefficiency, mess, and frustration for decorators, yet had remained unresolved since the invention of the paint roller. Harris tasked our team with developing a solution that was reliable, simple to use, and feasible to manufacture at scale.

 

The Solution

We explored a variety of mechanical approaches and ultimately developed the Lock ‘n Roll roller, featuring an innovative internal locking ring. The roller sleeve is placed on a specially designed cage, and when the lever is flicked, the internal ring expands to securely grip the inside of the sleeve. This design ensures the sleeve remains firmly in place during painting while still being easy to remove afterward. Throughout development, we balanced usability, manufacturing efficiency, and durability to deliver a practical solution for decorators.

 

The Results

  • Eliminated roller slippage, providing a reliable painting experience.

  • Simple, intuitive operation for both professional and DIY users.
