Introduction: No More Wire!

We plan to construct a wireless charger.

Step 1: Define a Problem


A)Who is the target customer?

The target customers are the adolescents that who utilize their phones the most. As a result, their phones shall decrease in power greatly.

What does the customer need/want?

Consumers want a device that powers their phones so they can use their phone for a longer period and do not have to rely on a nearby power outlet.

What must the product be able to do? Be specific

The product must be capable to be mobile to allow consumers to not be dependent on chords. Also, the product must charge faster or at the same rate as chords to be innovative. We must allow the product to be compact.

What is the anticipated cost to the consumer for this product?

This device should cost between $30 and $50, which is close to the range of current chargers, but slightly less.

What size should the product be, or what restrictions to size exist? What are the weight restrictions on the product?

The size of the product should be less than 64 inches squared. The biggest limit would be 81 inches squared. We expect the product to weigh no more than 10 ounces.

Are there preferences in the appearance features of the product (color, surface treatment, shape, material)? If so, describe them.

We prefer to use metallic substances for conductivity. Black and a flat surface with a oval shape would be preferred

Is there a specific material or materials that must be used? If yes, describe it. Safety and Legal Issues. Identify potential safety and legal issues that may arise from the use of this product.

Metal substances must be used because they have the best conductivity and are cost efficient. We must be cautious to not be electrocuted and prevent fire from sparks.

Identify considerations for the ergonomics of the product.

Our device shall have fillet edges to prevent cuts or etc. Also, we shall have a thin device so it is easily carried in one hand. Also, we shall use insulators to ensure consumers are not electrocuted.

I) Identify the environmental conditions relevant to the manufacture and use of the product (temperature, corrosion potential, dust or dirt, pressure, humidity, vibration, noise, degree of abuse, etc.).

We shall have a moderate temperature harmless to the human body or environment. The product will not cause corrosion. The pressure and humidity will be insignificantly affected. The vibration noise is planned to be at a minimum. The device shall a moderate level of abuse it can handle.

Will the product include any toxic or dangerous substances? What is the plan for disposal of the product at the end of its useful life?

The product will not contain components that are immediately harmful to consumers. We shall dispose of materials that take many years to decompose or recycle them.

What is the required service life of the product?

The required service life of this product should be greater than the phones that they will be charging. As a result, our device should have a service expectancy of 4 or more years. What is the anticipated length of time that the product will be produced before it is replaced by a newer version or alternate product?

The anticipated length of time that the product will be produced is 3 years before it is replaced by a newer version.

Will the product require routine maintenance during its service life? If yes, answer the following.

Our product shall not require routine maintenance during its service life. Additional Criteria

We shall implement a way for the device to be portable.

Step 2: Generate Concepts

Consumers are increasingly concerned with limited mobility with wired charging of mobile devices.Wireless charging technology poses a promising solution to this, but very few mobile devices are compatible for wireless charging. These are some solutions we came up with.

Step 3: Develop a Solution

This is one of the receivers we plan to use.

Step 4: Collect Materials

We gathered materials from Amazon and a relative.

Step 5: Construct and Test Prototype

We constructed a power mat for the receivers to charge the phones they are connected to.
