Solution Overview

Problem

Wearable electronic devices designed for the wrist are limited to a single arm due to mechanical and ergonomic constraints, making them non-convertible for use on the opposite wrist, which restricts usability and comfort.

Innovation Solution

A wearable device with a rigid structure featuring interchangeable stop elements that allow for ergonomic coupling on either wrist, maintaining symmetrical user interface access and functionality, enabling quick and easy reconfiguration between wrists.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device is designed with a fixed mechanical structure optimized for one wrist, then the wearability and interface accessibility are optimized for that specific wrist, but the device cannot be worn on the opposite wrist

Engineering Contradiction:
Improvewrist compatibilityVSAvoidinterface accessibility
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The device is divided into two symmetrical halves, each with identical functional components (display, buttons, speaker). This segmentation allows the device to be flipped and worn on either wrist while maintaining full functionality and interface accessibility from the user's perspective.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device employs bilateral symmetry rather than traditional asymmetry. The left and right sides are mirror images of each other, with identical buttons, displays, and functional elements positioned symmetrically. This symmetrical design enables the device to adapt to either wrist while preserving ergonomic operation.

Inventive Principle:
Principle #4Asymmetry

2Adaptability or versatility

If the device is designed as two different models for right and left wrists, then the wearability and interface accessibility are optimized for each wrist, but the device complexity and manufacturing cost increase

Engineering Contradiction:
Improvewrist compatibilityVSAvoidmodel variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single device design serves multiple functions by being wearable on both wrists. The symmetrical configuration allows one universal model to replace what would traditionally require two separate models, simplifying manufacturing, inventory, and user selection while maintaining full adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of creating asymmetric designs for each wrist, the invention inverts the approach by making the device perfectly symmetrical. This allows the device to be flipped 180 degrees and worn on the opposite wrist, eliminating the need for multiple models while maintaining optimized wearability.

Inventive Principle:
Principle #13The other way round (Inversion)

3Reliability

If the device structure is made rigid for structural integrity, then the manufacturing precision and reliability are improved, but the reconfiguration between wrists becomes difficult

Engineering Contradiction:
Improvestructural integrityVSAvoidreconfiguration ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device incorporates a dynamic reconfiguration mechanism that allows the rigid structure to be temporarily adjusted or reoriented. The symmetrical design with identical attachment points on both sides enables easy flipping and reattachment, maintaining structural integrity while facilitating quick wrist switching.

Inventive Principle:
Principle #15Dynamics

AI summary

Wearable device (10) comprising a rigid structure (12) with an at least partial function as a bracelet, to be associated with a first part of a user's body and provided with a base (16), and at least a user interface (14), in order to insert or receive information and/or to display data, associated with the rigid structure (12). The rigid structure (12) comprises a first stop element (24) and a second stop element (28) connected releasably to the base (16) so as to assume a first condition configured for ergonomic coupling with the first part of the user's body and a second condition configured for ergonomic coupling with a second part of the user's body, different from the first part and substantially symmetrical to the first part, maintaining the user interface (14) in a position of ergonomic use for the user and with access conditions for the user substantially corresponding to the first condition.
