My CAD Foldable Wall Hanger
This was one of my CAD practice projects, inspired by the need for a simple and space-saving wall hanger. In a boarding house, I often found myself looking for a place to hang my jacket, towel, or backpack without taking up too much space. I wanted to design a hanger that remained compact when not in use but could easily fold out whenever needed.
To begin the project, I researched different folding hook mechanisms and sketched a few concepts. I chose a pivoting triangular hook because it provided enough support while keeping the overall design simple. Using Fusion 360, I modelled each component separately before assembling them into a working mechanism.
I added a cylindrical pivot that allows the hook to rotate smoothly between its open and closed positions.
One of the biggest challenges was ensuring that all the parts aligned correctly while still allowing enough clearance for the hook to rotate freely. Small changes in dimensions affected the movement, so I repeatedly adjusted the angles and spacing until the mechanism functioned smoothly. Through this process, I gained a better understanding of mechanical joints, tolerances, and assembly design.
Although the project is relatively simple, it strengthened my CAD modelling skills and showed me how engineering can improve everyday products through thoughtful design. It also helped me appreciate the importance of designing products that are both functional and user-friendly.
1. Identified the Problem
I wanted to design a compact wall-mounted hanger that could fold away when not in use while still being strong enough to support everyday items such as a towel, jacket, or backpack.
2. Defined the Objective
My objective was to create a simple foldable mechanism that allowed the hook to rotate smoothly and lock securely in both the open and closed positions.
3. Designed the Main Hook
I began by modelling the triangular hook, which acts as the main hanging component. The shape was chosen to provide sufficient support while keeping the design compact and visually simple.
8. Tested the Rotation
I checked the movement of the hook through its full range of motion, ensuring that the pivot followed the guide slot correctly and that the mechanism opened and closed smoothly.
4. Added the Pivot Pin
A cylindrical pivot pin was created and positioned through the centre of the hook. This pin serves as the rotational axis, allowing the hook to swing between its folded and extended positions.
5. Designed the Side Plates
Next, I modelled two rectangular side plates that hold the rotating hook. These plates form the outer housing and provide structural support for the pivot mechanism.
6. Created the Locking Slot
To control the movement of the hook, I designed a curved locking slot inside one of the side plates. This slot guides the pivot pin during rotation and helps keep the hook stable in both positions.
7. Assembled the Components
After completing each individual part, I assembled the hook, pivot pin, and side plates to verify that all components aligned correctly and that the hook rotated without interference.
9. Refined the Design
Several adjustments were made to the dimensions of the pivot pin, locking slot, and clearances between components. These refinements improved the overall movement and prevented unnecessary friction during rotation.
10. Completed the Final Model
The final CAD model demonstrates a compact foldable hanger with a rotating hook, pivot mechanism, and integrated locking slot. Through this project, I developed a better understanding of CAD assemblies, moving joints, mechanical constraints, and designing functional products with practical everyday applications.
