Solution Overview

Problem

Traditional flag rods used in dance are cumbersome and stiff, leading to dancer fatigue and loss of gracefulness, as they do not allow for a secure and flexible connection between the flag and the rod, and fail to protect the rod from damage during use.

Innovation Solution

A flexible flag rod system featuring structurally reinforced ends and a folded binding mechanism that secures the rod, using endcaps, tabs, and a folded binding strip to provide a durable and customizable connection, protecting the rod from damage and allowing for easier maneuverability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional rigid flag rods are used, then structural strength is maintained, but dancer fatigue increases and gracefulness is lost due to stiffness and weight

Engineering Contradiction:
Improvestructural strengthVSAvoiddancer maneuverability
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent changes the physical parameters of the flag rod by using flexible materials instead of rigid ones, allowing the rod to bend and move with the dancer's body while maintaining sufficient structural strength to support the flag

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite construction with flexible rod made from materials that combine strength and flexibility, end caps that reinforce the ends while allowing movement, and fabric binding that provides both structural support and flexibility

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If traditional rigid flag rods are used, then structural stability is maintained, but dancer gracefulness deteriorates due to cumulative fatigue

Engineering Contradiction:
Improvestructural stabilityVSAvoiddancer gracefulness
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent modifies the structural parameters by introducing flexibility through material selection and design, enabling the rod to adapt to dynamic movements while maintaining end stability through reinforced end caps

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent transforms the static rigid structure into a dynamic flexible system that can adapt its shape and rigidity based on the movements and forces applied during dance performance

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If flexible materials are used for the flag rod, then dancer maneuverability is improved, but structural strength may be compromised

Engineering Contradiction:
Improvedancer maneuverabilityVSAvoidrod strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent uses composite construction combining flexible materials with reinforcing elements at critical locations (end caps) to maintain strength while preserving flexibility throughout the rod

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent applies different structural qualities to different parts of the rod - flexible material for the main body to enable movement, and reinforced end caps for structural strength and stability

Inventive Principle:
Principle #3Local quality

4Ease of operation

If the flag rod is made flexible, then ease of operation is improved, but reliability decreases due to potential damage from drops or impacts

Engineering Contradiction:
ImproveflexibilityVSAvoiddamage resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent incorporates protective end caps that act as cushioning elements at the vulnerable ends of the flexible rod, protecting them from damage during drops or impacts before the damage can propagate to the flexible rod material

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A method of manufacturing a flexible rod requires a flexible rod, a first endcap, a second endcap, a first tab, a second tab, and a folded binding. The method preferably includes a sheet. The method begins by terminally fixing both the first endcap and the second endcap onto the flexible rod. The first tab is affixed to the first endcap and a first exposed section of the flexible rod. The second tab is affixed to the second endcap and a second exposed section of the flexible rod. The flexible rod is positioned within the folded binding and along a middle fold-line of the folded binding. The first tab and the second tab are oriented away from the middle fold of the folded binding. A first seam is sewn through the folded binding along the flexible rod. A second seam is sewn through the sheet and the folded binding.
