Solution Overview

Problem

Traditional archery bow risers face challenges in attaching accessories, such as arrow rests and sights, due to the need for external attachment methods that disrupt the bow's balance and require additional stabilizers to compensate for weight shifts, leading to alignment issues and increased overall weight.

Innovation Solution

An archery bow riser design featuring mounts integrated within the centerline plane, including recesses and extensions on the upper wall and vertical sides, allowing for secure and balanced attachment of accessories without shifting the bow's center of gravity, eliminating the need for external attachment and additional stabilizers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If accessories are attached from the outside of the vertical wall of the sight window, then accessories can be mounted on the riser, but the bow's balance is compromised and additional stabilizers are required

Engineering Contradiction:
Improveaccessory attachment capabilityVSAvoidbow balance
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent integrates the accessory mounting function directly into the sight window structure by forming mounting holes through the sight window walls. This merging of the sight window and mounting features eliminates the need for external attachment mechanisms, allowing accessories to be mounted without compromising bow balance or requiring additional stabilizers.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If accessories are attached from the outside of the vertical wall, then accessories can be mounted, but lateral positioning and adjustment are required to center the accessory

Engineering Contradiction:
Improveaccessory mountingVSAvoidalignment adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent pre-positions the mounting holes within the sight window walls at locations that inherently center accessories relative to the riser and string. This preliminary positioning during manufacturing eliminates the need for field adjustment and alignment work, as accessories mounted through these holes are automatically centered.

Inventive Principle:
Principle #10Preliminary action

3Stability of the object's composition

If additional stabilizers are added to compensate for weight shift, then bow balance is restored, but overall bow weight increases

Engineering Contradiction:
Improvebow balanceVSAvoidoverall bow weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent extracts the balancing function from separate stabilizer components and integrates it directly into the riser structure through the sight window mounting system. By mounting accessories through the sight window walls, the weight is naturally balanced within the riser's center of gravity, eliminating the need for additional stabilizer weights or counterbalancing components.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An archery bow with a riser including a mount in an upper wall of a sight window of the riser may allow for a novel manner of mounting an archery accessory. Placement of the mount within a centerline plane of the riser may maintain the weight of the archery accessory along a center of the bow, thereby reducing or eliminating asymmetrically weighted bows or the need for an additional stabilizer to balance the weight of the archery accessory. Positioning the mount in the upper wall of the sight window additionally allows for coordination of the position of a secondary accessory, such as a sight, a light, or a camera, in addition to mounting an arrow rest, such as in a lower wall of the sight window, while maintaining the centralized weight advantages noted above.
