Archery Bow Stabilizer with Toolless Nested Weights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing archery bow stabilizers are too flexible, fail to adequately reduce vibration, and often require tools for weight adjustments, which can be inconvenient, especially in remote locations.
Innovation Solution
A bow stabilizer system featuring nested weights with universal threaded internal cores for toolless and secure installation, an embedded weight design at the stabilizer rod's distal end, a two-piece weight cap for improved rigidity, and an internal damping system comprising a mass and spring system tuned to the stabilizer's length, weight, and stiffness to dampen vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional stabilizer designs are used, then ease of operation is improved, but rigidity is insufficient and vibration reduction is inadequate
Solution Approach 1:
The stabilizer system is divided into separate modular components: a stabilizer rod, removable weight systems with threaded internal cores, and cap assemblies. This segmentation allows the weights to be easily attached and detached without tools while maintaining a rigid overall structure through precise threading and fit interfaces.
Solution Approach 2:
The stabilizer system combines different materials with complementary properties: the stabilizer rod is made from rigid materials to provide structural stability, while the weight systems use threaded internal cores that facilitate secure attachment. The composite construction of multiple materials allows the system to achieve both rigidity and ease of operation.
2Ease of operation
If traditional weight systems are used, then ease of operation is improved, but tool requirements create inconvenience in remote locations
Solution Approach 1:
The weight systems are designed with self-aligning threaded internal cores that enable toolless installation and removal. The threaded cores are integrated directly into the weight bodies, allowing archers to adjust weights using only their hands and fingers, eliminating the need for external tools especially important in remote hunting locations.
Solution Approach 2:
The weight systems feature nested construction where threaded internal cores are embedded within the weight bodies. This nesting allows the weights to be compact and self-contained, enabling easy attachment and detachment without requiring separate tool components.
3Ease of operation
If flexible stabilizer designs are used, then ease of operation is improved, but vibration reduction capability deteriorates
Solution Approach 1:
The stabilizer system uses strategically placed weights on the stabilizer rod to create counterbalancing moments that offset bow vibration and movement. The removable weight systems allow archers to adjust the counterweight configuration to specifically target and reduce vibration in different shooting scenarios.
Solution Approach 2:
The stabilizer system is pre-configured with weights and damping elements positioned to counteract vibration before the shot is fired. The internal damping system and pre-placed weights prepare the stabilizer to actively reduce vibration during and after the shot, improving stability before the archer needs to aim.
4Device complexity
If simple weight systems are used, then device complexity is reduced, but vibration damping capability is insufficient
Solution Approach 1:
The stabilizer system merges multiple functions into integrated components: the cap assemblies combine structural support, weight attachment, and vibration damping functions. The internal damping system is integrated within the stabilizer rod structure, combining simplicity with effective vibration reduction through a unified design.
Solution Approach 2:
The stabilizer system uses adjustable weight configurations and damping parameters that can be modified based on shooting conditions. The removable weight systems allow change in mass parameters, while the internal damping system provides adjustable vibration reduction characteristics, enabling optimization without significant complexity increase.
