Turnstile System

Turnstile System

1. Aesthetics

   • Suit the target market
     • Is it intimidating or user friendly in looks?
   • Quality of Finish
     • Hidden circuitry and components
     • Smooth surfaces, no sharp or dangerous points to the gate
     • Overall appeal of the gate that will make buyers interested

2. Cost

   • Cost per Gate
     • Affordable for the target market
   • Build Costs
     • To lower this use effiecent methods of production
   • Repair Costs
     • Easy access to new parts and expertise

3. Client

   • Who will use it
     • Students and staff
   • Who will buy it
     • School govonors

4. Environment

   • Materials
     • Recyclable
     • Limit the amount of unrecyclable materials in the product
   • Construction Methods
     • Using eco-friendly techniques
   • Transport of the gate to users
     • Maximize the amount of products being transported at once to reduce pollution

5. Safety

   • Safety in Construction
     • Following correct guidance to how machines involved in the production should be used
     • The maker should always be concerntraiting on the ongoing work
     • Appropriate clothing and protection e.g. goggles
   • Safety in Use
     • The gate has to be able to prevent a student forcing their way past
     • The gate opening and closing has to be able to move quickly but not so fast it doesn't allow the student through
   • Product Safety
     • No exposed electronics
     • Waterproof

6. Size

   • Height
     • Waist Height
       • Easier to clean
       • More visually appealing
       • Easier for students to bypass
     • Full Door Height
       • Less visually appealing
       • Harder to clean
       • Intimidating for younger students
       • Harder for students to bypass the system
   • Width
     • Take measurements of catering areas
     • Think about ergonomics and what people will have on them that will need to fit through

7. Function

   • Aim
     • Control the flow of pupils into catering areas
     • Count the number of students going in and out of catering areas
   • How will it do the Aim
     • Electronic circuits which will control a series of mechanisms
   • Automated or Manual Control
     • Manual
       • Harder for students to bypass if there is a prefect or staff member standing there
       • Friends can still stay together as it allows for human judgment
     • Automated
       • Easier for students to bypass
       • No prefect or staff member has to stand tat the entrances to the catering areas
       • There has to be a member of staff on duty anyway
       • Students may get cut off from friends with automated

8. Materials and Manufacturing Techniques

   • Materials
     • Plastics
       • Thermoplastics or thermosetting plastics
         • Thermosetting plastics is what a turnstile system should be made out of
       • Acrylic
         • Hardwearing, will not shatter but easily cracks and scratches
           • Used for signs, aircraft windows, washbasins
       • HIPS
         • Light, flexible and strong
           • Used for toys, boxes, containers and cases for electrical goods
       • Polyvinyl Chloride (PVC)
         • Lightweight, hardwearing
           • Used for pipes, guttering, bottles and window frames
       • Acrylonitrile Butadiene Styrene (ABS)
         • Has a high resistance to impact
           • Used for car components, tool handles and kitchen appliances
   • Manufacturing Techniques
     • CAD
       • Allows the product to be drawn accurately
       • The drawing can be transffered to printers or machienes such as 3D printers
     • PCB
       • A lot easier to produce on large scale
       • Cheap to make and they can save materials by being compacted
