Guaranteed Delivery Technology
Guaranteed delivery technology, ensures every book selected reaches it's new home for a seamless and positive experience.
What is Guaranteed Delivery Technology?
Guaranteed Delivery Technology uses strategically placed sensors to confirm every book reaches the delivery bin, giving students a reliable selection every time.
How does Guaranteed Delivery Technology work?
At the heart of this technology are sensors strategically placed to detect the passage of the book from the coil to the delivery bin. Here's a step-by-step breakdown of the process:
- Selection and Dispensing: When a student makes a selection, the machine's coil mechanism spins to release the chosen book.
- Invisible Detection Plane: As the book descends, it must pass through an invisible detection plane created by the machine's sensors. This step confirms that the book has successfully left the coil and is on its way to the delivery bin.
- Second Chance Mechanism: If the book gets stuck and fails to break the sensor plane, the machine does not simply stop. Instead, it automatically initiates a second coil spin, making another attempt to dispense the book to the student.
- Alternative Selection Prompt: In the rare event that the book does not break the sensor plane after the second attempt, the machine prompts the student to make a different selection at no cost. This ensures that no student leaves empty-handed due to a mechanical issue.

What are the benefits of Guaranteed Delivery Technology?
- Increased reliability: Students and staff can rely on Inchy's Bookworm Vending Machine to successfully deliver every book selection. This reliability enhances the overall experience and encourages continued engagement with the machine, supporting students' reading motivation and literacy goals.
- Seamless user experience: Guaranteed Delivery Technology ensures that students have a seamless and successful experience each time they interact with Inchy's Bookworm Vending Machine. Students no longer encounter failed dispensing events or lost selections — every token interaction results in a book in hand.
- Reduces maintenance interventions: The self-correcting dispensing mechanism resolves the majority of coil-jam events automatically, minimizing the need for staff or technician intervention and keeping the machine operational without interruption.
