Solution Overview

Problem

Existing smart glasses require cumbersome battery replacement processes due to the use of fixing means like screws or adhesives, necessitating tools for extraction.

Innovation Solution

A rod for devices, such as smart glasses, featuring a locking system with an extraction aid element that switches between closing and opening configurations to facilitate easy installation and removal of electronic components like batteries, using a locking system with elastic elements and manual command elements for seamless operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixing means like screws or adhesives are used to retain the battery, then the battery is securely fixed in the seat, but the battery replacement process becomes cumbersome and requires tools

Engineering Contradiction:
Improvebattery fixation securityVSAvoidbattery replacement ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking system is divided into separate components: a locking element with protrusions that engage with corresponding recesses in the battery, and a command element that controls the locking mechanism. This segmentation allows the battery to be securely held while enabling tool-free removal by actuating the command element.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking system is designed to be self-operating through the command element (such as a button or slider) that the user can directly manipulate. When the command element is actuated, it automatically releases the locking element, allowing the battery to be removed without requiring external tools or complex procedures.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a locking system with manual command element is used, then battery replacement becomes tool-free and simple, but the device complexity increases

Engineering Contradiction:
Improvebattery replacement easeVSAvoidlocking system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The locking element and command element are integrated into a unified locking system that is built into the rod structure. The command element is positioned to be accessible from the outside of the rod, allowing users to operate the locking mechanism without disassembling any parts of the rod or frame, thus minimizing the impact on device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The locking system is designed to accommodate different types of electronic components (batteries, electronic units) with standardized engagement features. The locking element can engage with various component types through corresponding recesses or engagement features, making the system versatile and reducing the need for multiple specialized locking mechanisms.

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