Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing external devices for battery-driven electronic apparatuses, such as imaging apparatuses, require a separate charging unit, leading to an increase in the number of parts and costs.
Innovation Solution
An electronic apparatus with a battery mounting unit and a connection unit that allows for external battery charging without the need for a charging unit in the external device, enabling attachable and detachable secondary batteries and selective charging of internal and external batteries, along with a charging control unit for authentication and efficient charging management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a charging unit is mounted in the external device to charge the secondary battery, then the external device can independently charge the battery, but the number of parts increases and cost increases
Solution Approach 1:
The charging unit in the electronic apparatus is designed to handle multiple charging scenarios: it can charge the internal secondary battery directly, and it can also charge external secondary batteries through the connection unit. This multi-functionality eliminates the need for separate charging units in external devices, reducing overall system complexity while maintaining independent charging capability.
Solution Approach 2:
The connection unit acts as an intermediary between the electronic apparatus and external devices. It enables the charging unit to access and charge secondary batteries in external devices without requiring those external devices to have their own charging units. This mediator approach resolves the contradiction by providing charging capability through a shared resource.
2Reliability
If a charging unit is mounted in the external device, then the external device can charge the secondary battery, but the cost of the external device increases
Solution Approach 1:
The charging unit is designed as a universal component that can charge any secondary battery connected to the electronic apparatus, whether internal or external. This eliminates the need for external devices to include expensive charging units, thereby reducing the cost of external devices while maintaining charging capability through the shared charging unit in the electronic apparatus.
3Duration of action of moving object
If the secondary battery is made attachable and detachable, then the electronic apparatus can continuously operate by substituting batteries, but the complexity of battery management increases
Solution Approach 1:
The battery management system automatically detects the presence, charging status, and compatibility of attachable and detachable secondary batteries. It autonomously manages charging processes, battery selection, and operation continuity without requiring complex user intervention. This self-service approach extends operational lifespan through easy battery substitution while keeping the management system relatively simple.
4Productivity
If the charging unit charges multiple secondary batteries simultaneously, then the productivity of battery charging is improved, but the control complexity increases
Solution Approach 1:
The charging unit can charge multiple secondary batteries simultaneously or sequentially based on demand. It implements partial charging actions where it can charge one battery at a time through different connection paths, or activate multiple charging paths simultaneously when multiple batteries are connected. This flexible approach improves charging productivity while keeping control complexity manageable by activating only the necessary charging paths.
