Ticket Dispenser Modular Housing With Lockable Security Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lottery ticket dispensers face issues with security, as the security cover is not separately lockable from the main door, leading to compromised security when re-threading tickets, and they are cumbersome and costly due to varying sizes for different ribbon configurations, increasing manufacturing and storage expenses.
Innovation Solution
A ticket dispenser with a lockable housing door and a pivotable security cover, featuring a rotatable central lock mechanism with multiple locking orientations, a pivotable ticket control cam to prevent ticket return, and modular design with slideable engagement elements for secure and efficient dispensing and interconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the security cover is not separately lockable from the main door, then the device structure is simpler, but the security is compromised when re-threading tickets
Solution Approach 1:
The locking mechanism is segmented into two independent parts: a main door lock and a security cover lock. The locking arm can engage with either the main door or the security cover independently, allowing separate locking and unlocking operations. This enables the security cover to be locked independently from the main door, maintaining security during re-threading operations without requiring full device disassembly.
Solution Approach 2:
The locking arm is designed to be dynamically reconfigurable, capable of engaging with different components (main door or security cover) based on operational needs. The system transitions between different locking states: both locked, main door only locked, security cover only locked, or both unlocked, providing flexible security control throughout the ticket dispensing and re-threading process.
2Adaptability or versatility
If different sizes of device are provided to accommodate different numbers of ribbons, then the adaptability is improved, but the manufacturing and storage expenses increase
Solution Approach 1:
A single standardized device size is designed to accommodate multiple ribbon configurations through internal arrangement variations rather than external dimension changes. The housing internal space is optimized to hold different numbers of ticket ribbons (one, two, or more) within the same external footprint, eliminating the need to manufacture multiple device sizes for different retail requirements.
Solution Approach 2:
Multiple ticket ribbons are arranged in a nested or compact configuration within the housing, allowing efficient space utilization. The ribbons can be positioned side-by-side or stacked within the same housing volume, enabling a single device size to serve multiple ribbon configuration needs without increasing manufacturing complexity or storage requirements.

AI summary
A ticket dispensing module comprising an elongate ticket dispensing aperture provided within a face of the ticket dispensing module, the elongate ticket dispensing aperture being a hole elongate in a plane parallel to the face when a door of the ticket dispensing module closed; and a housing body having opposed first and second faces with complementary slideable engagement elements, the first slideable engagement element of a first housing body engageable with the second slideable engagement element of a corresponding, second housing body, by relative displacement of the housing bodies along a direction of elongation of their slideable engagement elements, wherein at least one of the slideable engagement elements is tapered along its direction of elongation, wherein the slideable engagement elements of the first and second faces of the housing bodies are configured to prevent separation of the housing bodies transverse to the direction of relative displacement when they are engaged.
