Wedge Watch Accessory Filling Gap to Prevent Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watches often fit uncomfortably on wrists due to size mismatches, leading to unwanted rotation and sliding, as traditional wristbands cannot adequately fill the gap between the watch and the wrist, forcing wearers to choose between looseness or tightness.
Innovation Solution
A selectively attachable watch accessory, referred to as the 'Wedge in Place' (WIP) device, comprising a hypoallergenic rubber wedge pad, a bridge strap, and a wedge pin, which fills the gap between the watch and wristband, preventing rotation and sliding while allowing adjustable viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wristband is adjusted to fit a person's wrist size, then the watch becomes more secure, but the watch becomes uncomfortably tight or loose due to size increments
Solution Approach 1:
The invention divides the wristband system into multiple segments: the original wristband and an additional wedge insert. This segmentation allows independent adjustment of each component, enabling fine-tuning of the fit without replacing the entire wristband assembly.
Solution Approach 2:
The wedge insert is nested within the wristband structure, fitting into a dedicated slot or channel. This nesting allows the wedge to be integrated into the existing wristband design while providing additional adjustment capability.
2Stability of the object's composition
If a wristband is made tighter to prevent rotation, then the watch becomes more stable, but the comfort decreases
Solution Approach 1:
The wedge insert provides localized adjustment at the specific position where it is inserted into the wristband. This allows stability to be improved at the critical gap location without increasing tightness throughout the entire wristband, thereby maintaining comfort.
Solution Approach 2:
The wedge insert addresses the stability problem by adding a dimensional element (the wedge shape) that fills the gap between the watch and wrist, rather than simply tightening the wristband circumferentially. This dimensional approach provides stability without excessive tightness.
3Stability of the object's composition
If a wedge insert is added to fill the gap, then the watch stability improves, but the device complexity increases
Solution Approach 1:
The wedge insert is designed as a separate, modular component that can be independently manufactured and installed. This segmentation simplifies the overall system by allowing the complex adjustment function to be isolated in a single replaceable piece rather than integrated into the entire wristband structure.
Solution Approach 2:
The wedge insert system is designed to be dynamically adjustable and removable. Users can insert or remove wedges as needed, allowing the system to adapt to different situations without permanent structural modifications, thereby managing complexity through flexibility.

AI summary
The present invention is a selectively attachable watch accessory for filling the gap between a watch and/or wristband and a wearer's wrist. The watch accessory also keeps a watch from rotating or sliding along a wearer's wrist without making the wristband unusually tight and also can change the angle of the watch display. The watch accessory can include a wedge pad, a removable bridge strap and a removable wedge pin that secures the accessory to a watch and/or a wristband. The watch accessory allows a user to fill a gap between a watch and/or wristband and a wearer's wrist that is present on many watches to enhance the fit of a watch. This device is useful for traditional watches and smart watches that encourage a user to interact much more with a limb mounted screen.
