Slide-On Necktie Device With Flexible Bridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neckties require time-consuming tying and untying, can be uncomfortable, often the wrong length, and are prone to falling off or being misused, especially for those who do not know how to tie them or have dexterity issues, and they can harbor germs due to frequent handling.
Innovation Solution
A slide-on necktie device called the Tiekeeper, which consists of a flexible base with a lead-in notch, button passage, bridges, and a convex shield section, allowing for quick attachment and detachment to the shirt's top button, using a shortened necktie with a false knot that mimics the appearance of a tied knot, eliminating the need for tying and ensuring the correct length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional necktie is tied in a knot, then it can be worn formally, but it requires time-consuming tying and untying
Solution Approach 1:
The necktie is divided into a main body portion and a separate false knot portion. The false knot is detached from the main body, allowing the user to simply slide the pre-assembled unit onto the collar rather than tying a knot each time. This segmentation eliminates the time-consuming tying process while maintaining the formal appearance of a tied necktie.
Solution Approach 2:
The false knot is pre-attached to the necktie body during manufacturing, creating a pre-assembled unit that is ready for immediate use. This preliminary action eliminates the need for the user to perform the complex tying action each time they wear the necktie, significantly reducing preparation time while maintaining the formal appearance.
2Loss of time
If a necktie is kept in a noose to avoid tying, then time is saved, but the structure and material of the necktie deteriorate
Solution Approach 1:
By separating the false knot from the main necktie body and attaching it via a flexible bridge, the design allows the main necktie material to remain flat and unstressed during storage. The false knot can be independently positioned without constraining the necktie fabric, preventing the structural deterioration that occurs when neckties are kept in a permanent noose.
Solution Approach 2:
The flexible bridge connecting the false knot to the necktie body allows dynamic adjustment and movement. This flexibility enables the necktie to be stored in a relaxed state rather than a fixed noose configuration, preserving the material structure while still allowing quick donning and doffing.
3Reliability
If a necktie is tied tightly to prevent swinging, then it stays close to the body, but freedom of movement is restricted
Solution Approach 1:
The false knot is separated from the main necktie body by a flexible bridge, creating an articulated connection rather than a rigid fixed attachment. This segmentation allows the false knot to move independently with the wearer's movements, maintaining visual stability and proximity to the body without restricting the wearer's freedom of movement.
Solution Approach 2:
The flexible bridge acts as a thin, compliant connection element between the false knot and the necktie body. This flexible connection allows the false knot to adapt to body movements and maintain its position visually, while the flexibility itself prevents restriction of the wearer's range of motion.
4Ease of operation
If a clip-on button device is used to attach the necktie, then attachment is simplified, but the necktie is susceptible to movement and dislodgement
Solution Approach 1:
The false knot is permanently integrated with the necktie body through the flexible bridge connection during manufacturing. This merging creates a single unified component that cannot separate or dislodge, eliminating the reliability issues associated with separate clip-on attachments while maintaining the simplified appearance and ease of use.
Solution Approach 2:
The attachment mechanism (flexible bridge connecting false knot to body) is pre-assembled during manufacturing rather than requiring separate attachment steps by the user. This preliminary action ensures secure, reliable connection while maintaining ease of use, as the user simply slides the pre-assembled unit onto the collar without any additional attachment steps.

AI summary
One embodiment of a thin, flat, and angular triangular device for an improved necktie having on one edge a lead-in notch (10) which merges into a button passage (12) before merging into a cove (22). Two bridges (14), made of a flexible material so that they can be repeatedly bent without fracturing, are on ledges on top of the opposite edge from the lead-in notch (10). An untied, shortened necktie (30) is threaded through a false knot (24) and then threaded through the tie slot (26) at the top of the device. This allows the necktie to be joined to the Tiekeeper (28) device. This necktie device slides over the top shirt button by way of the lead-in notch and button passage before resting in the cove on top of the threads of the shirt's top button. Other embodiments are described and shown.
