Solution Overview

Problem

Conventional Klotski games lack an automatic mechanism to inform users when the decisive game piece has reached the exit, leading to uncertainty for inexperienced players or those who miss the game-ending condition.

Innovation Solution

Incorporating a prompter system with sensing elements on the decisive game piece and game board, along with a display or audio-visual prompter to indicate when the decisive piece reaches the exit, ensuring players are informed of game completion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional klotski game is used without automatic detection, then the game structure remains simple and cost-effective, but the user experience deteriorates because users may not realize when the game is over

Engineering Contradiction:
Improvegame completion detection reliabilityVSAvoidgame structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection with electronic sensing elements and processing modules that automatically detect when the decisive game piece reaches the exit position. The sensing elements detect the presence of the game piece through electrical signals, eliminating the need for users to manually determine game completion.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a feedback mechanism where the sensing elements continuously monitor the game board, the processing module evaluates the detected signals against game completion criteria, and the prompter provides immediate visual or audible feedback to users when the game is won, ensuring reliable game completion detection.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If sensing elements and prompters are added to the game, then automatic game completion indication is achieved, but the manufacturing complexity and cost increase

Engineering Contradiction:
Improvegame completion indicationVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent divides the detection system into separate functional modules: sensing elements embedded in the game board, a processing module that evaluates game state, and a prompter that provides user feedback. This segmentation allows each component to be manufactured independently and assembled into the complete game system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a processing module as an intermediary between the sensing elements and the prompter. This intermediary component receives signals from the sensing elements, processes the game state information, and triggers the appropriate prompter response, simplifying the overall system architecture and manufacturing.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The present application relates to a klotski game including a plurality of game pieces, a game board and a prompter. The plurality of game pieces includes a decisive game piece. The game board is configured to accommodate the plurality of game pieces and the game board is provided with an exit. The prompter is configured to indicate that a game of the klotski game is over when the decisive game piece is moved to a position corresponding to the exit on the game board.
