Lottery Ticket Receiving Structure for Compact Angled Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lottery-ticket issuing devices face challenges in efficiently stacking tickets due to the need for a larger horizontal space, as the ticket receiving mechanism must be larger than the ticket length to ensure vertical stacking, making it difficult to neatly stack tickets when space is limited.
Innovation Solution
The device allows tickets to be stacked at an angle from the vertical direction using a guide surface and supporting surface, reducing horizontal space occupation while maintaining regularity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the bottom wall of the ticket receiving mechanism is made larger in horizontal direction to ensure vertical stacking, then the regularity of ticket stacking is improved, but the horizontal space occupied by the device increases
Solution Approach 1:
The patent changes the stacking direction from vertical to oblique by introducing a guide surface at an angle. The guide surface is configured at an angle relative to the horizontal direction, causing tickets to stack in an oblique direction rather than vertically. This dimensional change allows the ticket receiving mechanism to occupy less horizontal space while maintaining regular stacking, as the tickets are arranged along the oblique guide surface rather than requiring a large horizontal bottom wall area.
2Area of stationary object
If the ticket receiving mechanism is made smaller in horizontal direction to reduce space occupation, then the horizontal space occupied is reduced, but the regularity of ticket stacking deteriorates
Solution Approach 1:
The patent introduces a guide surface as an intermediary element between the ticket output channel and the receiving cavity. This guide surface acts as a mediator that directs tickets into the receiving cavity at an oblique angle, enabling regular stacking even when the horizontal space is limited. The guide surface compensates for the reduced space by providing a controlled path for ticket entry, ensuring proper alignment and stacking order without requiring a large horizontal bottom wall area.
3Manufacturing precision
If tickets are stacked vertically on a large bottom wall, then stacking regularity is ensured, but the device complexity increases due to larger space requirements
Solution Approach 1:
The patent resolves the complexity issue by changing the stacking dimension from vertical to oblique. The guide surface is positioned at an angle that directs tickets along an oblique path into the receiving cavity. This dimensional change allows the system to maintain stacking regularity with a more compact horizontal footprint, reducing the overall device complexity while preserving the desired stacking precision.

AI summary
A lottery-ticket issuing device includes a ticket issuing mechanism and a ticket receiving mechanism. The ticket issuing mechanism includes a first base frame and a conveyance assembly disposed on the first base frame. The first base frame has a ticket issuing channel, and the conveyance assembly is configured to drive lottery-tickets to move along the ticket issuing channel. The ticket receiving mechanism includes a second base frame connected to the first base frame. The second base frame has a ticket receiving cavity communicating with the ticket issuing channel. The ticket receiving cavity has a guide surface and a supporting surface. The guide surface is configured to guide the lottery-tickets output from the ticket issuing channel to change a movement direction, so that the lottery-tickets are stacked on the supporting surface in a direction at an angle from a vertical direction.
