Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eyewear devices, such as smart glasses, face challenges in extending their operational life due to the need for frequent recharging and potential magnetic field leakage from exposed magnetic elements.
Innovation Solution
The eyewear device incorporates retractable magnetic hinges with detachable arms that include rechargeable power supplies and projectors, allowing for magnetic attachment and detachment, with a cavity to confine magnetic fields and prevent leakage, and inductive charging for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If magnetic elements are exposed for attaching detachable arms, then attachment strength is improved, but magnetic field leakage occurs causing harmful effects
Solution Approach 1:
The magnetic elements are extracted from permanent exposure and placed within a retractable hinge mechanism. When the arm is detached, the hinge retracts into a cavity that confines the magnetic field, preventing leakage while maintaining attachment capability when needed.
Solution Approach 2:
The hinge mechanism is nested within a cavity in the frame. The magnetic elements are housed within the hinge structure, which itself is nested in the frame cavity, creating multiple levels of containment that prevent magnetic field leakage while preserving functionality.
2Ease of operation
If arms are made detachable for ease of operation, then ease of operation is improved, but reliability of continuous power supply deteriorates
Solution Approach 1:
The arm assembly is segmented into detachable components including the arm itself and the power supply unit. This allows the power supply to be replaced independently when depleted, maintaining continuous operation of the eyewear device while preserving ease of arm detachment.
Solution Approach 2:
The power supply is designed as a replaceable component that can be discarded when depleted and replaced with a charged unit. The detachable arm design facilitates this replacement process, ensuring continuous power availability without permanent attachment constraints.
3Object-generated harmful factors
If hinges are made retractable to confine magnetic fields, then magnetic field confinement is improved, but device complexity increases
Solution Approach 1:
The retractable hinge mechanism is designed to operate automatically using magnetic attraction and spring forces. When the arm is attached or detached, the hinge self-actuates to extend or retract without requiring additional motors or complex control systems, minimizing added complexity while achieving magnetic field confinement.
