Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional wearable data acquisition devices have non-removable attachment arrangements and integral triggering mechanisms, making them difficult to use ambidextrously and requiring full device replacement if the attachment or trigger mechanism breaks.

Innovation Solution

A detachable trigger unit for wearable devices, comprising a trigger housing with a rotatable connector system and a protective membrane, allowing for easy attachment and detachment from the device housing, and featuring a strap housing for secure user attachment, enabling ambidextrous operation and component replacement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the attachment arrangement and trigger mechanism are integral with the housing, then the device structure is simplified and manufacturing is easier, but the device cannot be used ambidextrously and requires full replacement if components break

Engineering Contradiction:

Improveambidextrous operationVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device is divided into separate modular components: a housing unit and a detachable trigger unit. The trigger unit can be removed and reattached to different sides of the housing, enabling ambidextrous operation while keeping the overall device structure relatively simple through standardized connection interfaces.

Inventive Principle:

Principle #1Segmentation

2Ease of repair

If the attachment arrangement is non-removable, then the device structure is more stable and reliable, but the entire device must be replaced if the attachment or trigger mechanism breaks

Engineering Contradiction:

Improvecomponent replacementVSAvoidattachment arrangement

Core Design Contradiction:

Ease of repairVSReliability

Solution Approach 1:

The attachment arrangement transitions from a static non-removable connection to a dynamic detachable connection. The trigger unit can be securely attached when needed for reliable operation, yet easily detached and replaced if damaged, combining reliability during use with ease of repair through the reversible connection mechanism.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the trigger mechanism is integral with the housing, then manufacturing is simpler and cost is reduced, but the device lacks flexibility for different user preferences and conditions

Engineering Contradiction:

Improveuser customizationVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The detachable trigger unit serves multiple functions: it enables ambidextrous operation by being attachable to different sides, allows user customization based on preferences, and provides a replaceable component for repair. The universal connection interface simplifies manufacturing by using standardized parts that can be produced independently and assembled.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A detachable trigger unit for a wearable device (e.g., a wearable data acquisition device) includes (i) a trigger housing having a triggering mechanism for engaging a housing unit of the device; (ii) a strap housing detachably coupled to the trigger housing; and (iii) a protective membrane coupled to the strap housing and protecting a body part of a user. The trigger housing includes a first connector for receiving a corresponding second connector of the housing unit. The housing unit is rotatable about an axis substantially perpendicular to a bottom surface thereof.
