In this semester, we decided to make something practical and useful as our course project. Since most of our group members are interested in photography, we came up with the idea of fixing one of the pain points in photography: camera slider. They are currently either too heavy or too long, which serves no good to individual photographers. As a result, an innovative design is proposed, in an attempt to solving all current problems at a time. However, it is a shame that we are unable to make our design become a reality due to the pandemic.

In QFD House, we divide customer requirements into: portability, durability, stability, focus sharpness of the camera on the holder, interaction convenience, tolerable camera weight, battery life and system reliability. Based on the questionnaire, we assign different weights to different requirements, and give high weights to stability, portability and interaction convenience.

In Engineering Specifications, we adjusted the following Engineering parameters to meet these requirements: weight, length, bearing weight, maximum and minimum speed, battery capacity, price, endurance time, deformation, and maximum interaction distance. Finally, we consider slider length and shape variable as the two most important engineering parameters, and set our engineering target.

Our design scheme has the following advantages:

1. We design the motor and control system on both sides of the carbon-fiber tubes instead of the bottom of the camera platform, so that the slider track is more sensitive.

2. The addition of OLED screen enables us to control the movement of the head holder more intuitively, increasing the interaction of the design.

3. The electric control box stand and the support adopt the generative design, which ensures the stability and reduces the weight of the device.

4. The design of four carbon-fiber tubes allows the camera to travel twice as far as the tube length.
