Robot Battery Case with Rotating Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots with built-in rechargeable batteries cannot be easily replaced, leading to prolonged charging times when the power runs out, as users cannot swap in fully charged batteries.
Innovation Solution
A battery case design featuring an end cap, rotatable post, elastic member, and locking mechanism allows for easy installation and removal of batteries, enabling quick replacement with a fully charged battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If batteries are built into the robot, then the robot structure is simplified and manufacturing is easier, but the batteries cannot be easily replaced when power runs out
Solution Approach 1:
The battery case is divided into separable components: a housing and an end cap that can be easily detached from each other. This segmentation allows the end cap to be removed and reattached multiple times without affecting the housing or battery, enabling frequent battery replacements while maintaining a simple overall structure during manufacturing.
Solution Approach 2:
The end cap incorporates a rotatable post with a locking member that can dynamically change between locked and unlocked states. When the post rotates, the locking member engages or disengages from the housing, providing a mechanism that transitions from a fixed built-in state to a removable state, thus enabling easy battery replacement while maintaining structural integrity during manufacturing.
2Ease of operation
If a locking mechanism is added to enable easy battery replacement, then battery replacement ease is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the rotatable post. When the user rotates the post, the locking member automatically engages or disengages from the housing without requiring additional tools or complex mechanisms. This self-service approach enables easy battery replacement while minimizing the addition of complex components to the battery case structure.

AI summary
A battery case for a robot has a housing and an end cap. The housing defines a chamber for receiving a battery therein. The chamber has an open end. The end cap includes a cap that is used to cover the open end, a rotatable post rotatably passing through the cap and extending into the chamber, an elastic member arranged around the rotatable post and comprising an end abutting against the cap, and a locking member connected to the rotatable post and rotatable together with the rotatable post to a position where the locking member is engaged with the housing, thus locking the cap to the housing.
