Adjustable Counterbalance Handle for Golf Clubs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club and fishing rod handle counterbalance systems are not user-friendly for achieving a stable balance, requiring multiple attempts and offering limited fine adjustments due to the length and complexity of the counterbalance weight assembly.
Innovation Solution
A weight-adjustable-counterbalance apparatus featuring a shell with a container, restrainers, and a fastener system that allows for the selective addition of weighting members inside or outside the compartment, enabling easy adjustment of counterbalance effect without increasing the handle's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a threaded rod with a counterbalance weight is used to adjust the moment of inertia, then the counterbalance weight can be repositioned to change balance, but the longitudinal size becomes too long to allow for fine adjustments and the process requires many tries to achieve desired balance
Solution Approach 1:
The counterbalance weight is divided into multiple individual weighting members that can be selectively added or removed from the shell. Each weighting member can be independently positioned at different locations around the shell's circumference, allowing for fine-grained adjustment of the counterbalance effect without requiring a long threaded rod. This segmentation enables precise control over the moment of inertia by distributing weight strategically.
Solution Approach 2:
Instead of adjusting counterbalance along a single longitudinal dimension (threaded rod), the invention distributes weighting members around the circumferential dimension of the shell. This allows fine adjustments by changing the angular position and radial distribution of weights, effectively using the circumferential dimension to achieve what would otherwise require lengthy longitudinal adjustment.
2Adaptability or versatility
If a threaded rod with counterbalance weight is used, then the moment of inertia can be adjusted, but the system becomes complex and not user-friendly requiring many tries to attain desired balance
Solution Approach 1:
The counterbalance system is segmented into discrete, independent weighting members that can be individually manipulated. This simplifies the user interface compared to a threaded rod system where the entire weight moves together. Users can add or remove individual weighting members and position them independently, making the adjustment process more intuitive and easier to control for achieving desired balance.
Solution Approach 2:
The system transitions from a fixed-threaded-rod configuration to a dynamic assembly where weighting members can be selectively added, removed, and repositioned. This dynamic capability allows users to make incremental adjustments and achieve precise balance control through simple add/remove operations rather than complex threading adjustments.
3Adaptability or versatility
If a long counterbalance weight is used on a threaded rod, then the moment of inertia can be adjusted, but fine adjustments cannot be made due to the length of the weight
Solution Approach 1:
By dividing the counterbalance into multiple small weighting members rather than one large weight, the system enables fine adjustments. Each small weighting member can be positioned at different angular locations around the shell, allowing precise control over the moment of inertia. This segmentation provides granular adjustment capability that a single long weight cannot achieve.
Solution Approach 2:
The invention applies weight locally at specific positions around the shell rather than distributing it along a long rod. Each weighting member can be placed at an optimal location to achieve the desired balance effect, allowing precise local adjustments to the moment of inertia without the constraints of a long linear adjustment path.

AI summary
A weight-adjustable-counterbalance apparatus includes a shell and at least one or more weighting member selectively added to the shell. The shell includes a container having an annular lateral wall and an end wall, and defines an opening at an end and a compartment. A first restrainer releasably fits on the end wall and in a manner being prevented from rotating relative to the container. A second restrainer releasably fits on the end of the container and in a manner being prevented from rotating relative to the container. A fastener releasably secures the first retainer, the container, and the second retainer together. The fastener has a first end retained on the first restrainer, a body inserting into the compartment, and a second end extending outside the opening and engaging with the second restrainer. The at least one or more weighting member is added by releasably fitting on the fastener.
