Sustainable Design
Boot Camp
Julien HOLTZER
December 2024
Challenging new ideas !
Connected Objects for a Sustainable Future
Goals & expectations
Five days ahead
New original design to show
Problems solved and ideas finalized
Good balance between opportunities & constraints
Ready to embed electronics into future projects
Internet of Things
Talking objects
Ubiquitous computing
Internet of everything
Examples
Design your own idea
What could be "Internetized" ? Why ? Added-value first !
How much does it cost : buying and running
Impact for production / manufacturing / usage / recycling
Energy & IT costs : designing sustainable solutions
Find achievable solutions
Design hardware as a puzzle of hardware components
Design software as services for users
Objectives
Requirements
Capabilities
Expected results
-
Description of the Context you choose to address
-
Objectives that you want your object to achieve
-
Requirements that you identified
-
Solutions that you selected among possibilities
-
Capabilities to be achieved to implement the solution
-
Results that you are able to present / demo
- Monday : ideas, thoughts and fears, opportunities and risks = GOAL
- Tuesday : objectives, constraints, limits and solutions = IDEATION
- Wednesday : requirements, design, first pitch = VALIDATION
- Thursday : updates, technical explanations, arguments = APPROVAL
- Friday : final demo and feedback = LESSONS LEARNED
Agenda
Guidelines
Make the right choices according to the objectives you chose
Use your best skills and prefer a finalized design
Prototype accurately only when necessary
The good questions and accurate answers will be considered first
Prototyping must add value to your design
Accepted demos
Poster with 2D or 3D design, sketch of the global solution
(electronics + embedding object + user interface)
Hardware prototype with electronics, mock-up of the interfaces with simulated outputs
Courage !
Arduino is a simple tool
Identify all possibilities
Test and fail until a solution appears
Try and repeat for improvements
FINAL PRESENTATION
Twenty minutes allocated for each student or group
-
10 minutes for explanations
-
1 minute (before or after) of "teleshopping" presentation to the final user
-
5 minutes of Q&A with audience and/or jury
Context
-
Description of the context you have chosen to address
- Professional / Hobby / Education / ...
Questions to ask to yourself
WHAT ?
WHO ?
WHEN ?
WHY ?
HOW ?
WHERE ?
Improve until success
Rely on PDCA as a simple approach for every issue
Analyze and learn from your previous attempts
Accept changes by new plans
The five levels of the hierarchy are:
-
Physiological: Basic needs like food, water, and shelter.
-
Safety: Security, stability, and protection.
-
Love/Belonging: Social connections and relationships.
-
Esteem: Self-esteem, recognition, and achievement.
- Self-actualization: Fulfillment of personal potential and growth.
Impact of your object on individual needs
UML : modeling language for LOGIC
COST / PRICE / ROI : example
Designing the object : cost of 300 K€ during 1 year
Manufacturing 1000 objects : cost of 30K€ per batch
Estimated sales volume per year : 5000 sales of 1 object
Estimated time before profit : 2 years
PRICE : 200 € per item
Reminders
Hardware & software
How to power, how to connect
Components
What is Arduino ?
Electronics, design, DIY, open source, tinkering, IoT
Arduino hardware(s)
Cinque : RISC-V
Beatle
Software(s)
Processing (P5) : same IDE
Standard IDE for Arduino
Other Arduino IDE
ArduBlock : assemblement puzzle
approche dite "low-code"
Arduino Cloud : programmation en ligne
pour installer le minimum sur PC
et bien d'autres : Platform.io, Visual Studio...
Connect & power
USB : power / program / communicate
Serial : communicate / (program)
Wifi : communicate / (program)
Bluetooth : communicate
Ethernet : communicate / power
Wall mains : power
Batteries : power
and many others...
Sensors
Analog inputs: variations of values within a specified range.
Digital input : push-button with binary values
IC: Integrated circuits are more complex.
Actuators
Servomotors, stepper motors, DC motors, solenoids
Lights & displays
Buzzer, speakers
Sound & music synthesizers
You (already) are a
Hero of Arduino !
