Quad Lock: Smartphone-mounting solution developed with 3D printing

With features such as multiple lenses, image stabilization, and advanced software, modern smartphones can produce images that rival the quality of professional cameras.

Because of high levels of vibration, however, photos and videos taken on a smartphone while riding a motorcycle tend not to achieve this quality – not to mention the risks posed to phones that aren’t properly secured during such activities.

These challenges sent Melbourne-based company Quad Lock on a mission to develop a solution that would keep smartphones safe and protected – while maintaining professional photographic image quality.

The mission’s result? The Quad Lock Vibration Dampener, a mount for motorcycles that both stabilizes and protects smartphones. It features a dual-chassis suspension system with precision-engineered silicon grommets that absorb vibrations, reducing more than 90% of the high-frequency vibrations produced by motorcycles.

Designing the Quad Lock Vibration Dampener

For the Quad Lock team, the first step in designing the Quad Lock Vibration Dampener was to create a method that could repeatedly reproduce the real-world vibrations of a motorcycle. To do so, the team analyzed users’ riding behaviors and patterns, and worked with leading vibration experts to develop a testing method.

This method became a tool that enabled the Quad Lock team to create designs targeting specific frequencies. What eventually became the Quad Lock Vibration Dampener was successfully put through rigorous performance testing, with the final design being extensively tested by the device’s end users.

Overcoming validation challenges

To gather feedback and quickly implement it into design iterations, the Quad Lock team needed to create physical components that were strong enough to be used on test rigs and real-world applications, opening the door for 3D printing technology – specifically the Ultimaker S3, Ultimaker 3, and Ultimaker 2+.

The Quad Lock Vibration Dampener’s product development process consisted of two main phases: rapid concept iteration and real-world testing. More than 100 iterations of the design were produced, each testing factors such as the impact of dimensional changes, clearances, and material durometers.

This high turnover rate allowed the team to gather feedback, implement it, and produce the next iteration as cheaply and quickly as possible – with multiple iterations sometimes being produced in the span of a single day.

These designs were strong enough to withstand hours of testing on a vibration test rig, from which the team gathered valuable feedback and data. This kept the team’s morale and motivation high, and helped them streamline their production workflow, saving time and money.

A ‘fully embedded’ design process

Today, Quad Lock’s production facility is responsible for products distributed to millions of international customers. Additive manufacturing technology is now fully embedded in Quad Lock’s design, prototyping and production processes. This greatly benefits the company as it expands its product range, with mounting solutions for cars, runners – even interior walls of houses or office buildings.
