Hinged Archery Sight With Automatic Bowstring Alignment

Solution Overview

Problem

Existing archery sights are difficult to attach to a bowstring, requiring excessive time and visual alignment of apertures, especially in cold or wet conditions, due to the need to intertwine the sight with the bowstring and manually secure fasteners.

Innovation Solution

A hinged archery sight with pivotally secured front and back portions that automatically align when brought together, allowing for easy attachment without visual alignment, and featuring a hinge insertion portion that opens to receive the bowstring, securing it without extrinsic elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If prior art sights are secured by intertwining with the bowstring and manually tightening fasteners, then the sight can be securely attached, but the attachment process takes excessive time and requires visual alignment of apertures

Engineering Contradiction:

Improveease of attachmentVSAvoidattachment time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The sight is divided into front and back portions that can be separately positioned on the bowstring. The front portion has a U-shaped configuration that can be opened to receive the bowstring, allowing independent positioning without requiring simultaneous alignment of multiple components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fasteners are pre-positioned in recesses on the front and back portions before attachment. This preliminary positioning eliminates the need for visual alignment during attachment, as the fasteners automatically align when the front and back portions are brought together

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the archer must hold front and back portions while aligning apertures and securing fasteners, then secure attachment is achieved, but the procedure becomes especially difficult in cold and/or wet climates

Engineering Contradiction:

Improveattachment reliabilityVSAvoidease of attachment in adverse conditions

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sight structure provides self-alignment through its geometric design. The complementary shapes of the front and back portions automatically guide the fastener apertures into alignment when brought together, eliminating the need for manual visual alignment that becomes difficult in cold and wet conditions

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the sight is secured to an outer portion of the bowstring, then attachment is simplified, but wobble may increase after arrow release

Engineering Contradiction:

Improveease of attachmentVSAvoidsight stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The sight is divided into front and back portions that can be separately positioned on the bowstring. The front portion has a U-shaped configuration that can be opened to receive the bowstring, allowing independent positioning without requiring simultaneous alignment of multiple components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fasteners are pre-positioned in recesses on the front and back portions before attachment. This preliminary positioning eliminates the need for visual alignment during attachment, as the fasteners automatically align when the front and back portions are brought together
