Solution Overview

Problem

Existing archery technologies do not effectively utilize the outer diameter of an arrow shaft for radial support to achieve greater shooting accuracy with adjustable weight arrow points.

Innovation Solution

A weight adjusted target point system that includes a weight collar with a curved length and adjustable weight arrow tip, where the arrow shaft bore is formed to a depth of at least 60% of the weight collar length, allowing for precise adjustment of weight between 10 grains to 150 grains using a bonding substance and break-away segments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If adjustable weight arrow tips are used, then weight customization is improved, but shooting accuracy deteriorates due to lack of radial support

Engineering Contradiction:

Improveweight customizationVSAvoidshooting accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The weight collar is nested within the arrow shaft, with the arrow shaft bore formed to a depth of at least 60% of the weight collar length. This nesting arrangement provides radial support through the arrow shaft's outer diameter while allowing weight adjustment, resolving the contradiction between weight customization and shooting accuracy

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The arrow shaft acts as an intermediary between the weight collar and the external environment, providing radial support through its precisely ground outer diameter (tolerance of 0.0002 inch). This intermediary structure enables both weight adjustability and shooting accuracy by mediating the interaction between the adjustable weight system and the arrow's flight characteristics

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If weight collar is fixed, then shooting accuracy is improved, but weight adjustment capability deteriorates

Engineering Contradiction:

Improveshooting accuracyVSAvoidweight adjustment capability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The weight system is segmented into a weight collar and an adjustable weight arrow tip with break-away segments. Each segment can be independently adjusted or removed, allowing weight customization while maintaining the structural integrity and radial support provided by the weight collar's position in the arrow shaft

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The weight system transitions from a fixed state to a dynamic, adjustable state. The weight collar remains fixed in position within the arrow shaft to maintain radial support, while the weight arrow tip allows dynamic adjustment of weight through break-away segments, resolving the contradiction between stability and adaptability

Inventive Principle:

Principle #15Dynamics

AI summary

A weight adjusted target point preferably includes a weight collar and an adjustable weight arrow tip. The weight collar includes a round outer diameter and a curved length. The length is curved, such that a diameter of the middle of the weight collar is greater than a diameter at each thereof. An arrow tip shaft bore is formed through the weight collar. A length of the arrow shaft bore is at least the same as an outer diameter of the arrow shaft. The adjustable weight arrow tip includes a target tip and an adjustable length shaft. A largest diameter of the tip is equal to an outer diameter of the weight collar at an arrow tip shaft diameter end. The adjustable length shaft includes a plurality of break away segments. Each break away segment is preferably 10 grains, but other values may also be used.
