Product Dissection
The following notes were taken prior to and during product dissection.
Function/Purpose
The function of the product is to fasten materials together using staples.
- Hanging items from walls/ceilings/etc
- Attaching one item to another
- Shooting staples at targets (uncommon use)
Inputs/Outputs
- INPUTS: force of hand squeezing
- INPUTS: staples
- OUTPUTS: staple projectile
- OUTPUTS: recoil from handle
Typical Use Scenario
1. Pick up the staple gun and placed hand on handle
2. Positioned material with empty hand against item to be fastened to
3. Positioned gun against the material
4. Squeezed handled to release staple
5. Removed gun and checked to see if the materials were fastened together
6. No staple is present so repeats steps 2-5
7. Locates reloading place for staples
8. Removes slider on bottom of gun to check for staples
9. When no staples are present, finds staples and attempts to insert them
10. Positions staples over extruded part of staple loader and tries to close gun
11. When the slider will not close, repositions staples inside gun and closes slider successfully
12. Repeats steps 2-5
13. Finds that staple has successfully attached the two materials
Note: May have to unlock staple gun or adjust staple power before use. Do not always have to insert new staples.
Intended Use/Limitations/Annoyances
Intended functions:
- Fasten materials together by shooting a staple through them
- Ability to "lock" handle for more compact storage and/or safety reasons
- Adjustable power so that the user may shoot staples at higher or lower speeds
- Staples may be loaded by sliding the bottom of the stapler out, inserting the staples into the open compartment, then sliding and locking the bottom of the stapler back in place
Limitations/Annoyances:
- A great amount of force is required to squeeze the handle for shooting staples
- Difficult to adjust power
- No safety lock (lock that is already on the stapler is intended for storage purposes)
- Can't reach small/tight places
- Size is awkward (ie for carrying or storing)
Advantages:
- Sturdiness and solid weight
- Easy to load once the process is known
- Comfortable grip
- Power adjustment option makes product seem higher quality/more advanced
Different Users / Use Scenarios
- Force to dispense staples is high – people with small or weak hands may have difficulty using
- People with large hands may not be able to fit their hands in the handle.
- People may want to use it improperly – shooting staples at one another
- People who need to fit staples in small, tight places may not be able to get the gun into those places
Other Stakeholders
Identify other stakeholders besides the end user, such as those who manufacture, distribute, sell, purchase, assist, install, maintain, repair and manage the product's end of life. Document attributes of the product that affect these stakeholders.
