Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent chess boards lack real interactivity as piece movement still requires manual operation, and existing technologies like magnetic movement or mechanical arms are either limited in movement or aesthetically unpleasing and risky.
Innovation Solution
A levitated chess system where pieces can levitate relative to the board, utilizing a piece driving base with electromagnetic coils to generate repulsive magnetic forces, allowing pieces to move intelligently and jump over other pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If magnetic moving pieces are used, then pieces can move automatically, but one piece cannot cross other pieces and movement path is lengthened
Solution Approach 1:
The patent applies magnetic levitation to lift pieces vertically off the board surface, enabling three-dimensional movement. This allows pieces to jump over obstacles in the horizontal plane without increasing path length, as the vertical dimension provides a direct route across blocked areas.
Solution Approach 2:
The patent replaces traditional mechanical contact-based movement systems with magnetic field-based levitation and propulsion. Electromagnetic coils generate repulsive forces to lift pieces and directional magnetic fields to propel them, eliminating mechanical constraints that prevented crossing other pieces.
2Extent of automation
If magnetic moving pieces are used, then pieces can move automatically, but pieces may scratch the board after long-term movement and friction
Solution Approach 1:
The patent eliminates direct mechanical contact between moving pieces and the board by using magnetic levitation. Pieces are suspended above the board surface by repulsive magnetic forces, so movement occurs through magnetic fields rather than physical friction, preventing scratching and wear.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the board and moving pieces. The electromagnetic coils create a magnetic cushion that holds pieces aloft and propels them, serving as a non-contact transmission medium that avoids direct mechanical interaction and associated damage.
3Extent of automation
If mechanical arm or mechanical structure is used to move pieces, then pieces can be moved automatically, but the board becomes larger and less aesthetic
Solution Approach 1:
The patent replaces external mechanical arms with integrated electromagnetic coil systems built into the board surface. The coils are embedded within the board structure, using electrical energy to generate magnetic forces for piece movement, thereby eliminating the need for large external mechanical components.
Solution Approach 2:
The patent merges the movement mechanism directly with the board structure by integrating electromagnetic coils into the board itself. This consolidation eliminates separate mechanical arm components, keeping the board compact and aesthetically pleasing while maintaining automatic movement capability.
4Extent of automation
If mechanical arm or mechanical structure is used to move pieces, then pieces can be moved automatically, but there is a risk of mechanical injury
Solution Approach 1:
The patent replaces mechanical contact-based movement with magnetic field-based levitation and propulsion. Pieces are moved through non-contact magnetic forces, eliminating mechanical contact that could cause injury, wear, or failure of the movement system.
Solution Approach 2:
The patent uses magnetic fields as an intermediary to transfer movement forces from the board to the pieces. This non-contact interaction eliminates direct mechanical contact, reducing the risk of mechanical injury while maintaining precise and reliable piece movement.

AI summary
A levitated chess and a method for controlling the levitated movement of pieces are provided. The levitated chess includes a board; a plurality of pieces; and a piece driving base located inside the board, where, in response to a piece moving instruction, the piece driving base moves to a corresponding position below the piece to be moved; the piece driving base and the piece to be moved respectively generate repulsive magnetic forces against each other, so that the piece to be moved is levitated relative to the board; the piece driving base drives the piece to be moved to move to a placement position; and the piece driving base changes the generated magnetic force to enable the piece to be moved to fall down.
