Solution Overview

Problem

Conventional article capturing game machines struggle to respond to diversified display patterns, as their movement mechanisms remain standardized despite varied and creative arrangements of prizes, leading to a lack of interest and attraction in gameplay.

Innovation Solution

The game machine incorporates a lifting device with a retractable support member and a sensor system that allows for continued downward movement of the article capturing section after detecting an object, exerting a sustained load on the prize, and includes control mechanisms to manage this movement based on detection signals, enabling effective capture of prizes arranged in diverse patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the article capturing section uses a standardized movement mechanism, then the device structure is simple and easy to operate, but it cannot respond to diversified display patterns of articles

Engineering Contradiction:
Improveadaptability to diversified display patternsVSAvoidmovement mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lifting device is designed to dynamically adjust its movement characteristics based on detection signals. When the sensor detects an article at the bottom of the chute, the lifting device continues moving downward beyond the normal stop position, applying sustained load to dislodge hooked articles. This dynamic adjustment of movement behavior enables the system to adapt to various article display patterns without requiring complex mechanical reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the movement parameter (downward travel distance) based on detection conditions. Normally, the lifting device stops at a predetermined position, but when the sensor detects an article, the control mechanism allows continued downward movement, effectively changing the position parameter to achieve article dislodgement. This parameter change approach maintains structural simplicity while enhancing adaptability.

Inventive Principle:
Principle #35Parameter changes

2Force

If the article capturing section stops immediately upon detecting an object, then the operation is precise and controlled, but it cannot exert sustained load on articles hooked on the drop hole

Engineering Contradiction:
Improvesustained load on articleVSAvoidmovement control precision
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The sensor positioned at the bottom of the article chute provides feedback about article presence. When an article is detected, this feedback signal triggers the control mechanism to allow continued downward movement of the lifting device, applying sustained load to dislodge hooked articles. This feedback-based control maintains operational precision while enabling the necessary sustained force application.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The sensor detects articles in advance before the lifting device reaches the normal stop position. This preliminary detection allows the system to prepare for and execute continued downward movement, ensuring sustained load is applied to articles that are hooked or difficult to retrieve, while maintaining controlled operation through the sensor-triggered mechanism.

Inventive Principle:
Principle #10Preliminary action

3Force

If the lifting device continues moving downward after detecting an object, then it can exert sustained load to dislodge hooked articles, but it may cause damage or excessive force

Engineering Contradiction:
Improveload application to articleVSAvoidpotential damage from excessive force
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The sensor provides continuous feedback during the downward movement. When the sensor detects that the article has been dislodged or the lifting device has reached the bottom of the chute, the feedback signal triggers the control mechanism to stop further downward movement. This feedback control ensures sustained load is applied only as long as necessary, preventing excessive force and potential damage while effectively dislodging hooked articles.

Inventive Principle:
Principle #23Feedback

AI summary

To enabling actions that meet even diversified display patterns such as a prize hooked on a prize drop hole. An article housing section for storing articles, an article capturing section for capturing an article in the article housing section, lifting device for moving the article capturing section up and down, control device for controlling the movement of the article capturing section by the lifting device, and detection device for detecting that the article capturing section being moved downward by the lifting device strikes against any object including the article in the article housing section are provided. The control device performs control for operating the lifting device to continue to move the article capturing section downward even after the control device receives a detection signal from the detection device, and after the continued downward movement, stopping the downward movement of the article capturing section.
