Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adapters for connecting electric tools and battery packs are often bulky and inconvenient for users due to their complex structure and non-compact design, making them difficult to carry and use effectively.
Innovation Solution
A compact adapter with a simple structure featuring movable locking portions that securely connect and disconnect electric tools and battery packs, allowing for easy operation with a single hand by utilizing distinct unlocking directions for each interface, thereby simplifying the process and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional adapter structure is used to connect electric tools and battery packs, then the connection function is achieved, but the adapter becomes bulky and inconvenient for users to carry and use
Solution Approach 1:
The adapter structure implements nesting by placing the first locking portion and second locking portion within the housing space, with locking portions extending from opposite surfaces. The locking portions are positioned to engage with both the electric tool interface and battery pack interface simultaneously, nesting multiple functional elements within a compact adapter body to reduce overall size while maintaining connection capabilities
Solution Approach 2:
The adapter utilizes dimensional optimization by having the first locking portion and second locking portion extend from opposite surfaces of the housing in different directions. This spatial arrangement allows the locking mechanisms to engage with both interfaces simultaneously without increasing the adapter's overall volume, effectively using three-dimensional space to achieve compact design
2Reliability
If multiple locking portions are added to the adapter to connect both electric tool and battery pack interfaces, then the connection reliability is improved, but the structure becomes more complex
Solution Approach 1:
The adapter structure is segmented into distinct functional components: a housing and separate locking portions (first locking portion for electric tool interface, second locking portion for battery pack interface). Each locking portion is positioned on opposite surfaces of the housing and can operate independently to engage with its respective interface, dividing the complex connection function into simpler, modular segments that reduce overall structural complexity while maintaining reliability
3Ease of operation
If the locking portions are designed to move between locking and unlocking positions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The locking portions are designed to move automatically between locking and unlocking positions based on the engagement state with the interfaces. When the electric tool or battery pack is connected, the locking portions are driven into their locking positions by the connection force itself. Conversely, when disconnected, they return to unlocking positions, allowing the system to self-regulate the locking state without requiring additional control mechanisms or user intervention beyond simple connection/disconnection actions

AI summary
An adapter is configured to be adaptively connected to an electrical apparatus and a battery pack. The adapter includes a housing, a first locking portion, and a second locking portion. The first locking portion is movable relative to the housing between a first locking position at which the first locking portion is locked to the electrical apparatus and a first unlocking position at which the first locking portion is unlocked from the electrical apparatus, and the second locking portion is movable relative to the housing between a second locking position at which the second locking portion is locked to the battery pack and a second unlocking position at which the second locking portion is unlocked from the battery pack.
