Wearable Strap Interface for Modular Function Band Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges in being lightweight and portable while accommodating various modules, as the limited size of the device body restricts the integration of multiple functionalities, and existing solutions do not provide an efficient method for exchanging and compatibly coupling normal and functional connecting bands with the body portion.
Innovation Solution
A wearable device design that allows for easy attachment and detachment of normal and functional connecting bands, with the body portion capable of detecting the type of band coupled and executing user settings based on signals from the functional band, which includes various modules such as power supply, camera, location-based services, and healthcare functions, using electrical connection structures like adapters, spring pins, or pogo pins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the size of the device body is reduced to make the wearable device lightweight and portable, then the portability is improved, but the ability to equip various modules is worsened
Solution Approach 1:
The wearable device is divided into a body portion and separate connecting bands with modules. The body portion maintains a compact, lightweight design while functional modules are segregated into detachable connecting bands that can be attached or detached as needed, allowing module functionality without increasing body size.
Solution Approach 2:
The patent extends the functional dimension from the body portion to the connecting bands. By placing modules in the connecting bands rather than the body, the device gains additional functional space in a different spatial dimension, maintaining body compactness while enabling module integration.
2Adaptability or versatility
If different modules are mounted in the wearable device depending on user needs, then the versatility is improved, but the device complexity is worsened
Solution Approach 1:
The connecting bands are designed with universal interfaces that can be attached to the body portion through a standardized coupling mechanism. This allows different functional modules to be integrated through a single, unified attachment interface, reducing the complexity of module integration while maintaining versatility.
Solution Approach 2:
The connecting bands are designed to be dynamically attachable and detachable from the body portion. This dynamic configuration allows users to adjust the device functionality by adding or removing bands as needed, providing versatility without permanent complexity built into the device structure.
3Loss of information
If electrical connection structures are used to connect the body portion with the connecting bands, then the signal transmission is improved, but the risk of short circuits is worsened
Solution Approach 1:
The coupling portion acts as an intermediary between the body portion and connecting bands, providing controlled electrical connection points. This intermediary structure manages the electrical interface, allowing signal transmission while incorporating design features that prevent unintended electrical contact and short circuits between different electrical components.
