Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery ejecting structures in portable electronic devices occupy significant space and have complex mechanisms, making them bulky and difficult to miniaturize.
Innovation Solution
A battery ejecting structure utilizing an elastic restoring force from an elastic element to unlock a locked battery, comprising an ejecting element, a cover, a pushing element, and a blocking element, where the cover's rotation disengages the blocking element, allowing the pushing element to move via elastic force, unlocking the battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a traditional battery ejecting structure is used, then the battery can be locked and unlocked, but the device occupies significant space and has complex mechanisms
Solution Approach 1:
The cover integrates multiple functions: it serves as both a protective cover and a blocking element that restricts ejecting element movement. The cover's rotation mechanism combines the unlocking action with the cover opening motion, reducing the need for separate unlocking mechanisms and simplifying the overall structure while maintaining reliable battery retention
Solution Approach 2:
The elastic element serves dual purposes: it provides the pushing force to eject the battery when needed, and it maintains constant pressure to keep the battery securely locked during normal operation. The blocking element on the cover also serves both to restrict the ejecting element and to guide its movement, reducing the need for additional guiding structures
2Volume of moving object
If a traditional battery ejecting structure is used, then the battery can be locked and unlocked, but the device occupies significant space
Solution Approach 1:
The ejecting element is designed to move dynamically along an inclined surface within the container. When the cover rotates open, the blocking element disengages and the elastic element pushes the ejecting element along the incline, causing the battery to be ejected smoothly. This dynamic movement along the inclined surface allows for compact positioning while maintaining easy battery ejection
Solution Approach 2:
The elastic element acts as an intermediary that converts the rotational motion of the cover into the linear pushing motion needed to eject the battery. This intermediary mechanism allows for compact integration of the ejection function within the cover structure, reducing the space required for separate ejection mechanisms while ensuring reliable battery release

AI summary
A battery ejecting structure is applied to a portable electronic device which comprises a housing and a battery. The battery ejecting structure comprises an ejecting element, a cover, a pushing element and an elastic element. The ejecting element is movably located in the container of the housing; the cover is connected pivotally to the housing and covers the container to be a closed state, and the cover restricts the ejecting element to move via a blocking element; the pushing element is located in the housing, and the fixed member of the ejecting element is connected to the pushing element through the housing. Wherein when the cover is rotated relative to the housing to form an open state, the blocking element disengages from the container, and the pushing element is moved by an elastic restoring force of the elastic element to unlock the battery.
