Solution Overview

Problem

The installation of peep sights on compound bows is often time-consuming and inefficient due to the reliance on custom fitting and trial-and-error methods.

Innovation Solution

A method and system that utilizes a computer system to determine a preferred location for a peep sight on a compound bow by obtaining user eye height measurements and bow measurements, calculating the cam-to-arrow and right-to-D-loop distances, and using a processor to calculate the optimal peep sight location based on these inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If custom fitting and trial-and-error methods are used to install peep sights, then the peep sight can be properly aligned for the archer, but the installation process becomes time-consuming and inefficient

Engineering Contradiction:
Improvepeep sight alignment accuracyVSAvoidinstallation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary calculations of the optimal peep sight location based on the archer's eye height and bow specifications before installation. By pre-determining the exact mounting position using a calculator and database of bow measurements, the system eliminates the need for time-consuming trial-and-error adjustments during the actual installation process

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention introduces an intermediary calculation system that acts as a mediator between the archer's anatomical measurements and the peep sight installation. This intermediary tool (calculator/system) processes the relationship between eye height, bow geometry, and optimal peep sight position, providing precise installation guidance without requiring manual trial-and-error fitting

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual measurement and calculation methods are used to determine peep sight location, then customization for individual archers is achieved, but the process complexity increases

Engineering Contradiction:
Improvecustomization capabilityVSAvoidmeasurement and calculation process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system achieves universal applicability by creating a standardized calculation methodology that works across different archer sizes and bow types. The calculator uses universal parameters (eye height, cam-to-arrow distance, right-to-D-loop distance) that can be applied to any archer-bow combination, eliminating the need for complex custom measurement procedures for each individual case

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

Solution Approach 2:

The invention creates a replicated database of bow measurements and calculation algorithms that can be copied and applied to determine peep sight location. Instead of performing complex manual calculations for each archer, the system uses pre-stored bow specifications and standardized calculation formulas that can be quickly retrieved and applied, simplifying the customization process

Inventive Principle:
Principle #26Copying
