Archery Bow Sling Mount with Asymmetric Limb Cup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional archery bows are difficult to carry due to their shape and design, and existing carrying devices, while convenient, often result in larger size and greater weight, with methods like bow hoists or lifts being noisy or inconvenient.
Innovation Solution
The design incorporates a sling mount system with a proximal, intermediate, and distal portion, featuring a cord with a loop and adjustable cord lock, allowing for easier carrying and lifting of the bow, with the sling extending between limb members and a second sling mount for improved stowability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional carrying devices (backpacks, straps, slings) are used to carry the bow, then carrying comfort and convenience are improved, but device size and weight increase
Solution Approach 1:
The sling mount integrates the carrying function directly into the bow structure by attaching the sling to the limb cups, merging the bow and carrying device into a single integrated system. This eliminates the need for separate carrying devices, reducing overall weight and size while maintaining carrying convenience.
Solution Approach 2:
The limb cups serve dual functions: supporting the limbs during shooting and serving as attachment points for the sling during carrying. This multi-functionality eliminates the need for dedicated carrying hardware, reducing weight and device complexity while improving carrying convenience.
2Reliability
If mechanical clips or carabiners are used to attach the rope to the bow for lifting, then attachment reliability is improved, but noise is generated
Solution Approach 1:
The patent removes mechanical clips and carabiners from the system, extracting the noisy attachment mechanism. Instead, it uses a simple rope tied directly to the limb cups, which provides sufficient attachment reliability for lifting while eliminating the noise generated by mechanical fasteners.
Solution Approach 2:
The patent uses a simple, inexpensive rope with a knot-based attachment method instead of expensive, complex mechanical clips. While the rope may need replacement, this approach eliminates noise and reduces cost, accepting periodic replacement as a trade-off for noise-free operation.
3Device complexity
If tying the rope around the bow is used for attachment, then device complexity is reduced, but convenience and time efficiency deteriorate
Solution Approach 1:
The limb cups are pre-configured with specific geometric features that facilitate easy rope attachment. The cups' shape and positioning create natural attachment points, allowing users to quickly tie the rope without complex procedures. This preliminary design of the attachment interface improves convenience while maintaining simplicity.
4Volume of moving object
If the sling mount has a narrow intermediate portion for cord engagement, then stowability is improved, but attachment security may be compromised
Solution Approach 1:
The sling mount features an asymmetric cross-sectional shape with a narrow intermediate portion for compact stowability and a wider distal portion with a knob for secure cord attachment. This asymmetric design allows the mount to be compact when not in use while providing a large, secure attachment surface when needed, resolving the contradiction between size and security.

AI summary
In some embodiments, an archery bow comprises a riser, a first limb, a second limb, a bowstring and a sling mount. In some embodiments, the sling mount comprises a proximal portion, an intermediate portion and a distal portion. In some embodiments, the proximal portion is attached to the bow. In some embodiments, a width of the intermediate portion is less than a width of the distal portion.
