Adjustable Strap with Sliders and Snap Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing straps for electronic devices lack adjustable length and secure attachment mechanisms, limiting their versatility and comfort when worn or carried by users.
Innovation Solution
An adjustable-length strap with a strip of material, featuring a snap mechanism for secure attachment and sliders for length adjustment, allowing the strap to be removably coupled to electronic devices or their covers, and incorporating flexible magnet layers to reduce tangling and enhance user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length strap is used, then the structure is simple, but the versatility and comfort are limited
Solution Approach 1:
The patent applies the dynamics principle by incorporating sliders that enable the strap length to be adjusted dynamically. The sliders move along the strip of material, allowing users to change the strap length according to different needs, transforming a static fixed-length strap into a dynamic adjustable-length strap, thereby improving versatility without significantly increasing structural complexity
Solution Approach 2:
The patent applies segmentation by dividing the strap into modular components: a strip of material with exterior surfaces, internal layers including flexible magnet layers, snaps for attachment, and sliders for length adjustment. This segmentation allows each component to perform its specific function independently while contributing to the overall versatility of the strap system
2Reliability
If a simple attachment mechanism is used, then the device complexity is low, but the security of attachment is insufficient
Solution Approach 1:
The patent merges multiple attachment functions into a unified snap mechanism system. Snaps are coupled to the strip of material and work together with corresponding receptacles on electronic devices or covers to provide secure attachment. This combination of snaps and receptacles creates a reliable attachment system that maintains reasonable structural simplicity
Solution Approach 2:
The patent uses composite material construction for the strip, combining exterior surfaces (leather, fabric) with internal layers including flexible magnet layers. This composite structure enhances both the attachment security through magnetic assistance and the overall durability of the strap while managing complexity through integrated material design
3Ease of operation
If adjustable length is added, then the comfort and versatility improve, but the device complexity increases
Solution Approach 1:
The sliders enable dynamic adjustment of strap length, allowing users to customize the fit for comfort. The sliders move smoothly along the strip of material, providing an easy-to-operate adjustment mechanism that enhances user comfort without requiring complex mechanical systems
Solution Approach 2:
The strap adjustment system is designed to be user-operated without requiring additional tools or complex mechanisms. Users can easily slide the sliders along the strip to adjust the length to their preferred comfort level, making the adjustment process self-service and intuitively simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable strap provides enhanced comfort and versatility by allowing secure attachment and adjustable length, reducing tangling and improving user interaction with electronic devices.
Implementation Method 1
Adjacent portions of the strip may be magnetically attracted to one another, which may reduce tangling of the strap

AI summary
A strap may have a strip of material. A flexible magnet and other layers may be embedded between outer layers of the strip. The outer layers may be formed from leather or other natural materials, fabric, polymer, or other materials. The strap may have a snap mechanism that removably couples the strap to the item. The strip may have left and right portions that are coupled together using sliders and the snap mechanism. The sliders may be fixedly attached to respective end portions of left and right portions of the strip. A first of the sliders may have a slot that allows the first slider to slide along the right strip portion and a second of the sliders may have a slot that allows the second slider to slide along the left strip portion so that the length of the strap may be adjusted.
