Adapter Removal Pattern Triggers Host Hardware Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with captive batteries, such as wearable devices, face challenges in resetting power due to the absence of removable batteries, making traditional power reset methods impractical.
Innovation Solution
A system comprising an adapter port and a control circuit that detects a specific adapter removal pattern, temporarily decoupling the battery and adapter from the host hardware to initiate a hardware reset, allowing users to reset devices without physical battery removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is made captive (non-removable) for cost savings and waterproofing, then device reliability and manufacturing cost are improved, but the ability to perform power reset becomes lost
Solution Approach 1:
The patent introduces an adapter as an intermediary component that connects to the charging port. This adapter serves as a mediator between the user and the device's power system, enabling reset functionality without requiring direct battery access. The adapter detects removal patterns and triggers reset sequences through the existing charging infrastructure, thus preserving waterproofing while restoring ease of operation.
Solution Approach 2:
The patent replaces the mechanical battery removal action with an electrical signal-based reset mechanism. Instead of physically removing the battery to reset power, the system uses electrical signals detected from adapter insertion/removal patterns to trigger a software or firmware reset sequence. This substitution maintains the captive battery design while achieving the desired power reset effect.
2Ease of manufacture
If the battery is made captive (non-removable) for cost savings, then manufacturing cost is improved, but the ability to perform power reset becomes lost
Solution Approach 1:
The adapter acts as an intermediary that leverages existing manufacturing design (captive battery) while adding reset capability. By using the existing charging port infrastructure and adding a simple adapter component, the system achieves power reset functionality without requiring complex manufacturing changes or making the battery removable, thus preserving cost savings while improving ease of operation.
Solution Approach 2:
The adapter serves multiple functions: it connects to the charging port for power supply, detects user actions through insertion/removal patterns, and triggers reset sequences. This multi-functionality allows a single component to provide both charging and reset capabilities, maintaining manufacturing simplicity while enhancing operational flexibility.
3Ease of operation
If traditional power reset methods (battery removal) are used, then power reset capability is improved, but device design flexibility and waterproofing are worsened
Solution Approach 1:
The patent replaces the mechanical battery removal approach with an electrical signal-based system. The adapter detects electrical signals from insertion and removal actions, translating physical user gestures into electronic reset commands. This substitution maintains device design integrity and waterproofing while achieving power reset capability without mechanical battery access.
Solution Approach 2:
The adapter serves as an intermediary layer between the user's physical actions and the device's power management system. It translates simple insertion/removal gestures into complex reset sequences, preserving the device's sealed design while enabling easy power reset operation.
