Solution Overview

Problem

In pinball machines, stationary drains and flippers lead to decreased game interest and interactivity over time, as the ball can easily pass between fixed flippers and into the drain, making the game less challenging and less engaging.

Innovation Solution

A movable flipper drain device with a drain and ball-striking assembly mounted on a guide rod, allowing the drain and flippers to move leftward and rightward, featuring controllable flippers and an operation table with buttons to enhance game interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the drain and flippers are made stationary and fixed, then the structure is simple and stable, but the game interest and challenging decrease over time

Engineering Contradiction:
Improvestructural stabilityVSAvoidgame interest
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by transforming the stationary drain and flippers into movable components. The drain assembly is mounted on a guide rod allowing it to move leftward and rightward, while the flippers are designed to rotate about their longitudinal axes. This dynamic capability enables the drain and flippers to change positions during gameplay, increasing game interest and挑战性 while maintaining structural reliability through controlled movement mechanisms.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the drain and flippers are made stationary, then the device complexity is low, but the interactivity and challenging of the game are reduced

Engineering Contradiction:
Improvestructural complexityVSAvoidgame interactivity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements dynamics by enabling the drain assembly to move along the guide rod and the flippers to rotate, transforming a static structure into a dynamic interactive system. The operation buttons allow players to control these movements, significantly enhancing game interactivity and challenging while adding only moderate structural complexity through the guide rod mounting and rotation mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses operation buttons as intermediaries between the player and the drain-flipper system. These buttons serve as the interface that translates player input into controlled movements of the drain assembly and flippers, enhancing game interactivity without requiring complex direct control mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the flippers are fixed, then the ball can easily pass between them and enter the drain, but making them movable adds device complexity

Engineering Contradiction:
Improvegame flowVSAvoidmechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the flippers rotatable about their longitudinal axes and the drain assembly movable along the guide rod. This allows the flippers to actively redirect the ball away from the drain opening rather than passively allowing balls to easily fall in. The rotation mechanism and guide rod mounting add moderate complexity but significantly improve game flow by giving players active control over ball redirection.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A flipper drain device of a pinball machine is provided, including a fixed rack and a drain and ball-striking assembly. The fixed rack is mounted in the pinball machine and includes guide rods. The drain and ball-striking assembly is mounted to the guide rods, such that the drain and ball-striking assembly is leftward/rightward movable but not rotatable on the guide rods. The drain and ball-striking assembly has a drain opening and a flipper provided at each of a left part and right part thereof. The drain and ball-striking assembly includes an operation table, which is provided with an operation member. The operation member controls the drain and ball-striking assembly to selectively move leftward/rightward. The operation table is provided with an operation button on each of a left part and a right part thereof for respectively controlling the flippers of the drain and ball-striking assembly to rotate.
