Necktie Fastening System with Loop and Buttonhole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neckties lack effective solutions to control the movement of their broad ends, which can lead to unsightly flopping, potential damage, or harm when interacting with objects, and existing securing methods often detract from the aesthetic appearance or cause permanent damage.
Innovation Solution
A necktie design featuring a loop on the back of the wide end and buttonholes on the narrow end, allowing the narrow end to pass through the loop and be secured to a shirt button, limiting the movement of the broad end and maintaining appearance integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a tie clip is used to secure the necktie, then the movement of the broad end is controlled, but the aesthetic appearance is detracted and permanent wrinkles are caused
Solution Approach 1:
The patent uses the shirt buttons as an intermediary element to secure the necktie. Instead of directly attaching a clip to the tie, the tie's buttonholes engage with the shirt's existing buttons, using the shirt structure as a mediator to hold the tie in place without adding external hardware that would damage appearance or cause wrinkles.
Solution Approach 2:
The necktie is designed with integrated buttonholes that allow it to secure itself to the shirt buttons. The tie's own structure (with buttonholes) enables it to fasten to the shirt without requiring external fastening devices, making the system self-sufficient and avoiding aesthetic damage.
2Stability of the object's composition
If a tie tack is used to secure the necktie, then the movement of the broad end is controlled, but the aesthetic appearance is detracted and the material is permanently marred
Solution Approach 1:
The patent uses shirt buttons as an intermediary to secure the necktie. The buttonholes in the tie engage with the shirt's existing buttons, using the shirt structure as a mediator rather than penetrating the tie material with tacks that would cause permanent damage.
Solution Approach 2:
The patent replaces the mechanical penetration method (tacks piercing the tie) with a button-hole engagement system. Instead of forcing a tack through the tie material, the system uses buttonholes to receive buttons, substituting a non-damaging mechanical interaction for a damaging one.
3Object-affected harmful factors
If the broad end portion is allowed to move freely, then the aesthetic appearance is maintained, but the broad end may flop over the shoulder or contact objects causing damage
Solution Approach 1:
The patent uses shirt buttons as an intermediary anchor point to control the broad end's movement. The buttonhole engagement creates a gentle restraint that prevents flopping and contact with harmful objects while preserving appearance, as the restraint comes from the shirt structure rather than visible tie hardware.

AI summary
A necktie has an integrated system to limit movement of the free ends of the necktie when worn. The necktie has a wide end section and a narrow end section. The necktie has a selected width transition from the wide end section to the narrow end section. The overall length of the necktie is selected to allow the necktie to be secured to a person's neck using a selected knot-tying technique such that the wide end of the necktie is positioned at a selected location with respect to the person's waistline and such that the narrow end of the necktie is positioned behind the wide end of the necktie. At least one loop is secured to the back of the wide end of the necktie. The narrow end of the necktie passes through the loop. At least one buttonhole is formed through the narrow end of the necktie.
