Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and electronic components are integrated into the golf club head, then impact data recording and transmission capability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent embeds multiple electronic components (magnetometer, accelerometer, circuit board, battery) within a nested structure where the sensor weight acts as a container housing all components. The circuit board is positioned within the sensor weight, which itself is integrated into the club head structure, creating a compact nested arrangement that reduces overall complexity while maintaining functionality.
Solution Approach 2:
The patent combines multiple functions into a single integrated sensor weight assembly. The magnetometer, accelerometer, circuit board, and battery are merged into one unified component that can be installed as a single unit in the club head, simplifying installation and reducing the number of separate parts that need to be managed.
2Loss of information
If a magnetometer and multiple electronic components are placed in the club head, then impact data transmission capability is improved, but the weight of the club head increases
Solution Approach 1:
The patent employs a flexible circuit board with thin-film construction that minimizes weight while providing necessary electrical connections. The flexible nature of the circuit board allows it to be routed efficiently through the club head structure without adding significant mass, and the thin-film design reduces overall component thickness and weight.
Solution Approach 2:
The patent uses a magnetometer specifically for impact detection, which provides precise measurement capability while maintaining relatively low weight compared to other sensor options. The selection of specific low-weight components and optimization of their arrangement within the sensor weight assembly helps minimize the overall weight increase while maintaining data transmission capability.
3Reliability
If circuit boards are wrapped around batteries with multiple contact points, then electrical connection reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates pre-formed contact points and pre-configured circuit board patterns during the manufacturing process. The contact points are pre-positioned on the circuit board and in the battery assembly, so that when the components are assembled, the electrical connections are automatically established without requiring high-precision manual alignment during final assembly.
Solution Approach 2:
The patent uses a flexible circuit board as an intermediary element that bridges the battery and other electronic components. The flexible nature of the circuit board allows it to accommodate minor variations in component positioning while maintaining reliable electrical connections, acting as a buffer that reduces the impact of manufacturing tolerances on connection reliability.
