Solution Overview

Problem

Conventional racing pigeon foot rings have complex assembly processes, increased weight due to metal pivots, and high manufacturing costs, which affect the flying performance and efficiency of racing pigeons.

Innovation Solution

A racing pigeon foot ring shell design featuring a body with pivoting holes and engaging portions, and a movable member with protruding pivots and engaging buckles, allowing for a pivot connection without additional metal pivots, reducing components and assembly steps, and incorporating a lightweight structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metal pivot is used to connect the body and movable member, then the connection strength is improved, but the overall weight and manufacturing cost increase

Engineering Contradiction:
Improveconnection strengthVSAvoidoverall weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent integrates the pivot structure directly into the movable member by forming a protruding pivot on the movable member itself, eliminating the need for a separate metal pivot component. This merging of functions reduces component count and overall weight while maintaining the pivot connection strength through direct structural integration.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts and eliminates the separate metal pivot from the assembly, removing this unnecessary component that added weight and cost. The pivot function is retained through the protruding pivot structure that is part of the movable member, achieving the same connection purpose without the harmful weight addition.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a metal pivot is used to connect the body and movable member, then the connection reliability is improved, but the manufacturing cost increases

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the pivot function with the movable member structure, eliminating the need for a separate metal pivot component. This integration reduces the number of parts that need to be manufactured, assembled, and quality-checked, thereby reducing manufacturing complexity and cost while maintaining connection reliability through the integrated protruding pivot design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent removes the separate metal pivot component from the manufacturing process, eliminating the associated costs of producing, inventorying, and assembling this separate part. The pivot function is achieved through the protruding pivot structure that is formed as part of the movable member, simplifying the supply chain and manufacturing process.

Inventive Principle:
Principle #2Taking out (Extraction)

3Stability of the object's composition

If multiple separate components are used in the assembly, then the structural stability is improved, but the assembly process complexity increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the pivot structure into the movable member itself, reducing the total component count. This integration maintains structural stability because the protruding pivot is an integral part of the movable member, providing the same pivot connection function with fewer discrete parts, thereby simplifying the assembly process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the pivot function from the separate component category and integrates it into the movable member structure. This resegmentation of the design reduces the number of detachable components while maintaining the functional segmentation needed for the pivot connection, simplifying assembly without compromising structural integrity.

Inventive Principle:
Principle #1Segmentation

AI summary

A racing pigeon foot ring shell (1) comprises a body (10) and a movable member (20). A first terminal (11) of the body (10) is formed with at least one pivoting hole (110), and a second terminal (12) opposite to the first terminal (11) is formed with a first engaging portion (120). A pivoting terminal (21) of the movable member (20) is formed with at least one protruding pivot (210), and the at least one protruding pivot (210) is detachably inserted into the at least one pivoting hole (110) to be pivotally connected with the body (10). An engaging terminal (22) opposite to the pivoting terminal (21) is formed with a second engaging portion (220), and the second engaging portion (220) is detachably engaged with the first engaging portion (120). The body (10) and the movable member (20) can form a pivoting connection without an additional metal pivot.
