Solution Overview

Problem

Traditional archery bow risers face challenges with asymmetric weight distribution due to accessories being mounted off-center, requiring additional counterbalance weights, which increases the overall weight of the bow.

Innovation Solution

An archery accessory with a sight arm that connects to the bow riser in a vertical centerline plane, featuring horizontal and vertical adjustment systems to position the sight element centrally, eliminating the need for off-center mounting and counterbalance weights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If accessories are mounted on the vertical side wall of the riser (traditional mounting method), then the sight can be attached to the bow, but the weight distribution becomes asymmetric, requiring additional counterbalance weights which increases the overall weight of the bow

Engineering Contradiction:
Improvesight mounting capabilityVSAvoidoverall bow weight
Core Design Contradiction:
Ease of operationVSWeight of moving object

Solution Approach 1:

The patent transitions the mounting location from the vertical side wall (traditional 2D mounting surface) to the centerline plane (introducing a new spatial dimension). This dimensional shift allows the sight to be mounted centrally on the riser, achieving symmetric weight distribution and eliminating the need for counterbalance weights, thereby reducing overall bow weight while maintaining sight attachment capability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If accessories are mounted on the vertical side wall of the riser, then the sight can be attached, but the center of gravity becomes unbalanced, requiring additional counterbalance weights

Engineering Contradiction:
Improvesight attachmentVSAvoidcenter of gravity balance
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies asymmetry in reverse by creating symmetry in the weight distribution. By mounting the sight on the centerline plane rather than the asymmetric vertical side wall, the weight distribution becomes symmetric, balancing the center of gravity and eliminating the need for additional counterbalance weights, thus improving stability without compromising sight attachment

Inventive Principle:
Principle #4Asymmetry

3Ease of manufacture

If the sight is mounted off-center on the vertical wall, then attachment is achieved, but additional counterbalance weights are needed which complicates the device

Engineering Contradiction:
Improvesight mountingVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent introduces a new mounting dimension (centerline plane) that eliminates the need for counterbalance weights. This dimensional change simplifies the overall device by removing unnecessary components while maintaining the sight mounting function, thereby reducing device complexity without sacrificing ease of manufacture

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An archery accessory, such as an archery sight, may attach to a riser of a bow along a centerline plane of the riser. This positioning may prevent or reduce any change in balance of the bow. The archery sight may include a sight element that may be adjusted in a horizontal direction by a horizontal adjustment system and in a vertical direction by one or more vertical adjustment systems.
