Battery-less Clasp for Wearable Contactless Payments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wearable devices, such as watches, lack integrated battery sources for enabling smart features like contactless payments and secure data transactions due to design, recharging, and water resistance issues, making it difficult to incorporate battery-less solutions that are both functional and aesthetically pleasing.
Innovation Solution
A battery-less active and passive hybrid device with a secure element for storing payment applets and biometric data, integrated into a clasp device that can be mounted on traditional wearables, allowing for wireless communication and data transactions without the need for a built-in battery, using a bendable board and NFC technology for power transfer and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery is integrated into traditional wearable devices to enable smart features like contactless payments, then the device can perform wireless communication and data transactions, but it causes design complexity, frequent recharging needs, and water resistance issues
Solution Approach 1:
The patent extracts the battery component from the wearable device, creating a passive wearable that relies on an external battery pack for power. This allows the wearable to gain smart features through wireless communication capabilities without integrating a battery internally, thus avoiding design complexity, recharging issues, and water resistance problems while maintaining the ability to perform contactless payments and data transactions
2Adaptability or versatility
If a battery is integrated into traditional wearable devices to enable contactless payments, then wireless communication functionality is achieved, but it requires frequent recharging or battery replacement
Solution Approach 1:
The patent segments the power supply system from the wearable device itself, placing the battery in a separate external pack that connects to the wearable. This allows the wearable to maintain contactless payment capability while the battery duration issue is managed externally, eliminating the need for frequent recharging or replacement of an integrated battery
3Adaptability or versatility
If a battery is integrated into traditional wearable devices for smart features, then wireless operation is enabled, but it compromises water resistance and aesthetic integrity
Solution Approach 1:
By extracting the battery from the wearable device and placing it in an external pack, the patent eliminates the compromise to water resistance that would result from internal battery integration. The wearable maintains its original sealed structure and aesthetic integrity while still enabling wireless communication capabilities through the external power source

AI summary
A clasp device adapted for use with a wearable device including a main portion and at least one resiliently deformable arm extended from the main portion along a curvature and configured to be switchable between a normal state and a deformed state; wherein in the normal state a free end of the deformable arm is separated from an opposed end of the main portion a first distance and configured to form a first cavity or passage with the main portion for receiving or engaging with the wearable device; while in the deformed state the free end of the deformable arm is resiliently deformed to enable it to be separated from the opposed end of the main portion a second distance and configured to form a deformable second cavity or passage with the main portion for enabling insertion or removal of the wearable device into or from the clasp device.
