Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads lack an effective mechanism for securely attaching and detaching weight objects, which affects the club's performance and user convenience.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a weight object is attached to a golf club head by rotating the weight object, then the weight object can be securely attached and detached, but the weight object may rotate unintentionally during use, reducing reliability
Solution Approach 1:
The patent applies preliminary anti-action by incorporating a rotation prevention part that exerts a counteracting force against the rotational force applied during attachment. This prevention mechanism is built into the structure beforehand, ensuring that when the weight object is attached, any rotational tendency is immediately counterbalanced, preventing unintentional rotation during use while maintaining ease of attachment and detachment operations.
2Reliability
If a shape change mechanism is used to fix the weight object, then the attachment security is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the fixing mechanism into distinct functional components: a shape change mechanism that alters the configuration of the weight object receiving portion, a rotational force applying part that generates attachment force, and a rotation prevention part that stabilizes the weight object. This segmentation allows each component to perform its specific function efficiently, achieving secure attachment without requiring an overly complex integrated system.
Solution Approach 2:
The patent applies dynamics by utilizing a shape change mechanism that can dynamically alter the configuration of the weight object receiving portion between different states (e.g., open/closed, extended/retracted). This dynamic capability allows the mechanism to transition between attachment and detachment states, providing secure fixation when needed while maintaining operational flexibility, thereby achieving reliable attachment without permanent complex structures.
3Reliability
If the weight object is pressed against the rotation prevention part by rotational force, then the weight object is securely fixed, but the attachment mechanism becomes more complex
Solution Approach 1:
The patent applies merging by combining the rotation prevention part with the weight object receiving portion or the shape change mechanism into an integrated structure. Rather than being separate components, the rotation prevention functionality is merged into the existing attachment mechanism, allowing the same structural elements to serve multiple functions: receiving the weight object, applying rotational force for attachment, and preventing rotation during use. This merging reduces overall device complexity while maintaining reliable fixation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides a secure and user-friendly attachment of weight objects, enhancing the club's performance by ensuring the weight object remains fixed and prevents unwanted rotation, thereby improving the golfer's control and consistency.
Implementation Method 1
The weight object or the weight object receiving portion has a shape change mechanism that enables the weight object or the weight object receiving portion to change a shape of itself
Data Source
AI summary
A golf club head includes a weight object and a weight object receiving portion that is provided on an outer surface of the head and in which at least a part of the weight object is housed. The weight object or the weight object receiving portion includes a shape change mechanism that enables the weight object or the weight object receiving portion to change a shape of itself. The weight object receiving portion includes: a rotational force applying part that applies a rotational force on the weight object as a reaction generated when the weight object is pressed by the shape change; and a rotation prevention part that is located at a position abutting against the weight object when the rotational force is applied and that stops the weight object from being rotated by the rotational force and prevents rotation of the weight object.
