Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist-worn devices require a wristband buckle and adjustment holes, making the wearing and removal process inconvenient and affecting user experience.
Innovation Solution
A wrist-worn device with a wristband featuring detachable ends and a memory metal wire that naturally maintains an annular shape, eliminating the need for a buckle and allowing easy on and off wearing, and incorporating positioning grooves and protrusions for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wristband buckle and adjustment holes are used to connect the wristband, then the wrist-worn device can be stably worn on the user's wrist, but the wearing and removal process becomes inconvenient and time-consuming
Solution Approach 1:
The patent removes the traditional wristband buckle and adjustment holes from the wristband structure. Instead of using a separate buckling mechanism, the wristband is designed as a continuous loop that can be directly placed on the wrist, eliminating the need for buckling operations and significantly improving the convenience of wearing and removal while maintaining stable support through the elastic properties of the wristband material
Solution Approach 2:
The patent divides the wristband into multiple segments or sections with different functional characteristics. The first section includes the first installation cavity for sensor components, while the second section includes the second installation cavity for the device body. This segmentation allows each section to be optimized for its specific function while maintaining overall structural integrity and comfort
2Reliability
If a wristband buckle and adjustment holes are used to connect the wristband, then the wrist-worn device can be stably worn on the user's wrist, but the device complexity increases
Solution Approach 1:
The patent eliminates the wristband buckle and adjustment holes from the design, significantly simplifying the overall structure. The wristband is designed as a continuous loop without separate fastening components, reducing the number of parts and assembly steps while maintaining stable wearing through the elastic properties of the material and the positioning grooves that secure the device body
Solution Approach 2:
The patent combines the functions of the wristband into a unified continuous loop structure that integrates both the support function and the wearing function. The positioning grooves are directly formed on the device body, eliminating the need for separate fastening mechanisms, and the wristband material itself provides the necessary elasticity and support without requiring additional structural elements
3Reliability
If a wristband buckle is used to connect the wristband, then the wrist-worn device can be securely fastened, but material costs and assembly costs increase
Solution Approach 1:
The patent removes the wristband buckle and adjustment holes from the design, eliminating the need for these additional components and their associated manufacturing and assembly costs. The wristband is designed as a continuous loop that relies on the elastic properties of the material and the positioning grooves on the device body to maintain secure fastening, significantly reducing material and assembly expenses
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
Enables quick and easy wearing and removal of the device without the need for buckling, reduces material and assembly costs, and enhances user experience by providing stable support without a wristband buckle.
Implementation Method 1
The memory metal wire is configured with a memory state of being annular in a natural state, so that the band body naturally maintains an annular shape, and the wristband naturally maintains a wearing state
