Flexible Handle Assembly for Battery Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery assembly securing mechanisms are often difficult to operate and insecure, leading to frustration, reduced usage, and increased wear or breakage due to improper use.
Innovation Solution
A removable battery assembly with a flexible handle assembly that includes an attachment portion, handgrip, supports, and protrusions, where the tension from pulling the handgrip causes the flexible handle to flex, releasing the protrusions from secure engagement with the device, allowing easy removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure engagement mechanism is used to lock the battery assembly in place, then the reliability of battery retention is improved, but the ease of operation for removal deteriorates
Solution Approach 1:
The handle assembly is designed to transition from a rigid locked state to a flexible unlocked state. When removal force is applied, the handle flexes dynamically, causing the protrusions to disengage from the battery compartment recesses. This dynamic transition allows the mechanism to provide strong retention during normal use while enabling easy removal when needed.
Solution Approach 2:
The mechanical state of the handle assembly changes from rigid (locked) to flexible (unlocked) based on applied force. This parameter change allows the same structure to provide both secure retention and easy removal functionality, resolving the contradiction between reliability and ease of operation.
2Reliability
If a complex securing mechanism is used to ensure secure battery engagement, then the reliability of battery retention is improved, but the device complexity increases
Solution Approach 1:
The handle assembly combines multiple functions into a single integrated structure: it provides the gripping surface for user interaction, contains the protrusions for secure engagement, and acts as the flexible element for unlocking. This merging of functions reduces the number of separate components needed, thereby reducing device complexity while maintaining reliable battery retention.
Solution Approach 2:
The handle assembly serves multiple purposes: it is the user interface for removal, the locking mechanism through its protrusions, and the flexible element that enables transitions between locked and unlocked states. This multi-functionality eliminates the need for separate mechanisms, reducing overall device complexity.
3Reliability
If excessive force is required to disengage the securing mechanism, then the reliability of secure engagement is improved, but the ease of operation deteriorates and wear or breakage increases
Solution Approach 1:
The flexible handle assembly acts as an intermediary between the user's pulling force and the protrusions. When the user pulls on the handle, the flexibility of the handle assembly gradually transfers this force to disengage the protrusions from the recesses, rather than requiring sudden excessive force. This mediates the interaction, making removal easier while maintaining secure engagement during normal use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and intuitive disengagement of the battery assembly from the device, reducing user effort and minimizing wear or breakage, while maintaining secure engagement when not in use.
Implementation Method 1
the tension placed on the flexible handle assembly causes the flexible handle assembly to flex so that the first protrusion and the second protrusion are drawn toward each other

AI summary
A removable battery assembly is configured to provide electrical power to a device. The device may include, for example, an oxygen concentrator, a ventilator, a respiratory therapy device, an electromagnetic radiation therapy device, a nebulizer, and/or other devices. The battery assembly is configured to securely engage the device, while allowing for quick and easy disengagement and removal. The mechanism for disengaging the battery assembly from the device may be intuitive to users, such that users may not have to spend substantial time learning how to remove the battery assembly from engagement.
