Solution Overview

Problem

Traditional archery bow risers face challenges in attaching accessories, requiring lateral adjustment to center them with the bow's center plane and adding weight that disrupts balance, necessitating additional stabilizers.

Innovation Solution

An archery bow riser with integrated mounts positioned within the centerline plane, allowing for secure attachment of accessories like arrow rests, sights, and stabilizers without shifting the bow's balance, using recesses, elongated grooves, or extensions that align with the bowstring path.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If accessories are attached from the outside of the vertical wall of the sight window, then accessories can be securely fastened to the riser, but lateral positioning adjustment is required to center the accessory with respect to the riser and string

Engineering Contradiction:
Improveattachment securityVSAvoidpositioning adjustment
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mount is pre-positioned within the centerline plane of the riser during manufacturing, eliminating the need for lateral adjustment of the accessory. The mount's location is predetermined to align with the bowstring path, so when the accessory is attached to the mount, it is automatically centered relative to the riser and string without requiring additional positioning operations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If accessories are attached to the vertical wall of the sight window, then accessories can be mounted on the riser, but the added weight shifts the center of gravity of the bow, requiring additional stabilizers

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

Solution Approach 1:

The mount is positioned asymmetrically within the centerline plane of the riser, specifically located to balance the weight distribution. By placing the mount and its attached accessory directly on the centerline plane, the weight is distributed symmetrically relative to the bow's balance point, preventing lateral shifts in the center of gravity and eliminating the need for additional stabilizing elements.

Inventive Principle:
Principle #4Asymmetry

3Adaptability or versatility

If mounts are positioned outside the centerline plane, then accessories can be attached to the riser, but the accessory is not centered with respect to the riser and string

Engineering Contradiction:
Improveaccessory attachmentVSAvoidalignment accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The mount serves multiple functions simultaneously: it provides a secure attachment point for the accessory, maintains precise alignment with the centerline plane, and ensures the accessory is centered relative to the riser and string. By integrating the mount directly into the riser structure at the centerline location, it becomes a multi-functional element that combines attachment, positioning, and alignment capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An archery bow with a riser including a mount in a centerline plane of the riser above a lower 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 above the lower 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.
