Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a wired connection is used between fencer's equipment and detection station, then hit detection accuracy and priority determination are improved, but fencer freedom of action and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The wired connection between fencer's equipment and detection station is substituted by wireless transmission means (such as radio frequency communication), allowing fencers to move freely without physical constraints while maintaining accurate hit detection and priority determination capabilities.
2Ease of operation
If a completely wireless system is used to improve fencer freedom of action, then ease of operation is improved, but hit priority determination accuracy deteriorates
Solution Approach 1:
The patent implements a wireless communication system that substitutes the traditional wired mechanical connection. This wireless system uses electromagnetic signals to transmit hit detection data from the fencer's equipment to the detection station, maintaining measurement precision while enabling complete freedom of movement for the fencers.
Solution Approach 2:
The patent introduces wireless communication means as an intermediary between the fencer's equipment and the detection station. This intermediary transmits electrical signals related to hits wirelessly, enabling accurate priority determination without requiring direct wired connections, thus resolving the contradiction between wireless operation and detection accuracy.
3Ease of operation
If wireless communication means are added to achieve complete wireless operation, then device complexity increases, but fencer freedom of action is improved
Solution Approach 1:
The patent integrates wireless communication means into the existing fencer's equipment, making the system multi-functional. The same equipment that detects hits also transmits this data wirelessly, eliminating the need for separate wired connections and reducing overall system complexity despite adding wireless capabilities.

AI summary
A fencing equipment 100 is described, which is usable for sports or games, comprising a fencing weapon 1, suitable to deliver a hit on a target X, and a detection apparatus 2, electrically connected to each other. The weapon 1 and detection apparatus 2 comprise electric components configured to form, in the fencing equipment 100, an autonomous electrical detection circuit, having an autonomous ground, Such an electric detection circuit is configured to take a resting condition or, when the fencing weapon 1 delivers a hit on the target X, a signalling condition. Such a circuit is further configured to generate an electrical signal Vm which is representative of either the resting or signalling conditions, and which is indicative, in the signalling condition, of at least one electrical property of the target X. A fencing uniform, usable in conjunction with the equipment, and moreover a fencing system and a method for the determination of fencing scores employing the equipment, are also described.
