Klotski Chess Exit Detection Using Magnetic Hall Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional klotski games lack an automatic mechanism to inform players when the decisive game piece has reached the exit, leading to uncertainty for users unfamiliar with the game or those who miss the game-ending event.
Innovation Solution
Incorporation of sensing elements and a prompter in the game pieces and board to detect the decisive game piece's movement to the exit, using magnetic elements and Hall sensors for accurate detection, and a display or audio-visual prompt to indicate game completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional klotski game without automatic detection is used, then the game structure remains simple, but the user experience deteriorates because users may not realize when the game is over
Solution Approach 1:
The patent replaces manual verification of game completion with an automated sensing system. Magnetic elements embedded in game pieces interact with Hall sensors in the game board to automatically detect when the decisive piece reaches the exit position, substituting the mechanical/manual checking process with an automated electromagnetic detection system.
Solution Approach 2:
The patent introduces magnetic elements and Hall sensors as intermediary components between the game pieces and the detection system. These intermediaries enable indirect detection of piece positions through magnetic field interactions, allowing the system to sense game completion without direct mechanical contact or complex visual systems.
2Ease of operation
If sensing elements and prompters are added to automatically detect game completion, then user experience improves through clear indication, but device complexity increases due to additional components
Solution Approach 1:
The game system performs self-detection of completion status through the integrated sensing elements and prompters. The system automatically monitors piece positions and notifies users of game completion without requiring external verification, making the detection process self-service and eliminating the need for users to manually check game state.
Solution Approach 2:
The patent employs visual indicators such as color-changing LEDs or display elements to communicate game completion status. The prompter uses color changes or light emissions to provide clear, intuitive feedback to users when the decisive piece reaches the exit, making the detection result immediately recognizable.
3Measurement precision
If magnetic elements and Hall sensors are used for detection, then detection precision improves, but manufacturing complexity increases
Solution Approach 1:
The patent uses inexpensive magnetic elements and Hall sensors that are readily available and easy to integrate. These components are chosen for their low cost and ease of manufacture, allowing precise detection functionality to be added without significantly increasing manufacturing complexity or expense.
