Cardboard Models

Introduction: 

Glueing aesthetic elements 

Here you can see me glueing the ‘ears’ of the robot, as an aesthetic element. These elements allow me to visualise how the final product will look like.

Model of Robot Jewellery Box

I have designed a cardboard aesthetic model of the jewellery box. As the model was being made, I realised that the measurements of the CAD model were too large, and thus this model is also too large. To improve this, I will scale each of the measurements by .75.

Incorrect size

This photo demonstrates the incorrect size of the design, as mentioned in the above text box. 

Inaccurate cutting/sizes

In this photo, you can see how some of the cardboard has been cut inaccurately, which is a) not aesthetically pleasing and b) creates problems with the balance and stability of the design. To improve this, I will make sure the measurements and cuts are exact and precise respectively, as well as using machines like the laser cutter for cuts that are required to be accurate (e.g, some parts of the legs).

Cardboard Models

Introduction: 

Leg movement mechanism

The next model I had to design is one to test the leg movement mechanism for my design. The legs of my final jewellery should be able to turn/rotate. The mechanism for this test model was created using cardboard and a wooden dowel (to allow the legs to rotate).

Laser cutting for model #2 test

Here you can see my adobe illustrator file, which has the shapes of the different components I require for the legs of my design. I can use this file to use the laser cutter, which will cut cardboard into these shapes.

Idea #1

The initial idea for the leg movement mechanism was to insert a thin wooden dowel into a bent piece of cardboard as shown in the picture. However, this idea presented 2 issues. Firstly, there were no appropriately sized wooden dowels for the holes in the cardboard (circumference of the dowels were too large). Secondly, even if the dowel’s thickness was small enough, it would be very unlikely that the holes in the cardboard would be perfectly sized for it, meaning the fit could be too tight or loose, affecting the movement.

Idea #2 model

My final idea for the leg movement mechanism involves using 2 components: a single piece of cardboard glued between the 2 legs and a component that goes in between the two legs. The purpose of the of the first component is to make sure the legs move together, rather than both legs moving separately. The purpose of the second component is to prevent the legs from moving too far back

Cardboard Models

Introduction: 

Laser cutting

The final model I made was to test the lid for my design. This lid is to cover the face of the jewellery box. To test this, I used the laser cutter to cut separate parts of the lid, which I later glued together. Since my first aesthetic design was not of correct size, I had to also cut out more cardboard parts to simulate the face of my actual design.

Mechanism in CAD


Here is a refined version of the leg movement mechanism that I designed in CAD. The top surface of this component would be glued to the bottom of the head of the design, such that the component will be place between the 2 legs. The wooden dowel will go through both of the legs.

Lid design

This photo shows my lid design in action. As you can see, the lid cover the bottom component, which is supposed to simulate the face of my final design. This bottom component has raised parts just inside of the edges, which I will also include in my final design.

Design in CAD

Here you can see my lid design I made using cardboard implemented in CAD. I changed the colour of the raised edges in this CAD model in order see the actual lid mechanism more clearly, however in the final design, the raised edges will also likely be the same colour as the rest of the head.

CAD Design

Introduction: 

Previous CAD model

The CAD model I made right before my final model can be seen here. This model was not completed, as the only goal of making this was to test different joining techniques to choose which will be used in the final model and where. The joints I tested were butt joints, mitre joints, lap joints, dovetail joints, and finger joints.

Previous 2 CAD models

Before starting my final CAD model, I had previously designed 3 CAD models. 2 of them can be seen here. The one of left was created to view my quick sketch in a 3D representation, and to try adding or removing parts and seeing how the design will turn out. The CAD on the right was to experiment with the aesthetics of the various components, as well as improve upon the leg movement mechanism I made out of cardboard in real life.

Final design first stage

Here you can see the first stage of my final design. In this render, the lid is placed on. The edges of the lid are slightly raised, and this is because in a discussion with my client regarding the previous versions of this design, she said: “I’d love to have a mirror on the jewellery box design so I can easily see how the pieces look when I try them on”. My client changed her mind about having a mirror later on.

Further feedback from client

Here you can see an email conversation with my client after our in-person discussion. After receiving user feedback, I redesigned the main compartment/storage until to have 3 levels, each designates for a specific type of jewellery.

CAD Design

Introduction: 

Separate storage by type of jewellery

Here you can see the refined version of the design. I got rid of the component in the center of the storage unit since it wasn’t required anymore. To store the rings/earrings, added a felt ring holder at the bottom. To store the bangles, I added a cylinder to store the bangles (while taking into account the size in order to make sure they fit and won’t fall out). To store the necklaces, I placed 2 hooks on the sides of the storage unit.

User feedback

The image on the left shows the colours the client requested for this design. As shown above, the client liked the three storage systems I implemented to store each of here different types of jewellery.

Pattern design

In the final discussion with my client for deciding the design, she asked for one more feature, which was to have a pattern design on both the top and the lid of the jewellery box. She said these patterns will make the design more attractive and beautiful. We search the web for patterns she may like, until she decided on the two shown on the left (both found on freepatternsarea.com).

Pattern design on material

Here is how this patterns will look like in real life. These 2 images are screenshots of my final CAD design, where the patterns have been extruded downwards. When I make my design in real life, I will use the laser cutting to engrave these patterns into the pieces of wood.
