Two-Band Wearable Attachment System With Concealment Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional watch bands for wearable electronic devices are uncomfortable and inconvenient to attach and detach, often catching or pinching the user's skin, and require multiple steps and dexterity, which can lead to user frustration and discontinuation of device use, especially due to frequent recharging needs.
Innovation Solution
A two-band attachment system comprising a sizing band and a retaining band, both made from compliant materials like fluoroelastomeric polymers, with a concealment aperture and guide bed for easy interlacing around the wrist, and a post for resistance to separation, allowing for rapid and comfortable attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional watch bands with clasps or elasticated bands are used, then the device can be attached to the wrist, but the bands may uncomfortably catch, pinch, and/or pull the user's skin
Solution Approach 1:
The watch band is divided into two separate bands (first band and second band) that can be independently adjusted and attached. This segmentation allows each band to be optimized for comfort and function, reducing skin irritation by eliminating the need for bulky clasps or elasticated sections that直接接触皮肤
Solution Approach 2:
Different portions of the attachment system have different properties: the bands have smooth surfaces for comfort, while the rear surfaces incorporate retention mechanisms. The first band has a first retention mechanism and the second band has a second retention mechanism, allowing localized functionality without compromising overall comfort
2Reliability
If conventional watch bands with multiple-step clasps are used, then the device can be securely attached, but multiple steps and dexterity are required for attachment and detachment
Solution Approach 1:
The retention mechanisms are designed to automatically engage and disengage without requiring user dexterity or multiple steps. The first retention mechanism on the first band and the second retention mechanism on the second band work together to provide automatic securing when the bands are brought together, and automatic release when separated
Solution Approach 2:
The two separate bands with their respective retention mechanisms are designed to work together as an integrated system. When the free end of the first band is passed through the second band and the retention mechanisms engage, they combine to provide secure attachment without requiring complex clasps or multiple adjustment steps
3Adaptability or versatility
If smart watches require regular recharging and data connection, then the device remains functional, but the frequent attachment and detachment increases user frustration
Solution Approach 1:
The attachment system automatically secures itself through the retention mechanisms, eliminating the need for multiple manual adjustment steps. This self-securing feature reduces the time and effort required for frequent attachment and detachment operations
Solution Approach 2:
The bands are pre-configured with retention mechanisms that are ready to engage immediately when the bands are brought together. This preliminary preparation of the retention systems eliminates the need for complex assembly steps during each attachment operation

AI summary
Attachment systems for attaching a wearable electronic device to a user including a sizing band and a retaining band are disclosed. The sizing band includes at least one sizing eyelet and a band-insertable end. The retaining band includes at least a post for insertion into the sizing eyelet of the sizing band and a concealment aperture configured to receive the band-insertable end of the sizing band. On a bottom surface of the retaining band can be a recessed guide bed configured to guide the band-insertable end along the bottom surface of the retaining band. A wearable electronic device can couple to both the sizing band and the retaining band by accepting an end portion of each band into receiving channels extending into opposite sidewalls of the housing.
