Housing Mounting Mechanism With Elastic Latching For Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing housing mounting mechanisms for portable electronic devices lack a secure and efficient method for detachable mounting and demounting, particularly for battery or SIM card replacement, as they often require complex mechanisms or tools.
Innovation Solution
A housing mounting mechanism featuring a body, a housing, a first mounting member with mounting portions, and a latching member with a guiding surface, where the latching member is movably mounted between body wall portions, using an elastic member to lock and unlock the mounting portions, and a release hole for tool-assisted disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional housing mounting mechanism is used, then the housing can be mounted to the body, but the mechanism requires complex structures or multiple tools for secure attachment and detachment
Solution Approach 1:
The latching member is divided into distinct functional portions: a first latching portion for engaging the mounting member to secure the housing, and a second latching portion accessible through the release hole for triggering release. This segmentation allows independent operation of mounting and demounting functions, simplifying the overall mechanism while maintaining security.
Solution Approach 2:
The second latching portion acts as an intermediary element that translates the user's manual input through the release hole into the movement needed to disengage the first latching portion from the mounting member. This intermediary mechanism enables tool-free operation without requiring complex external tools or devices.
2Device complexity
If a simple mounting mechanism is used, then the device complexity is reduced, but the security and reliability of housing attachment is compromised
Solution Approach 1:
The latching member is designed as a movable component that can dynamically transition between a locked position (where the first latching portion secures the mounting member) and an unlocked position (where the latching portions are disengaged). This dynamic capability allows a simple mechanism to provide secure attachment during normal operation while enabling easy release when needed.
Solution Approach 2:
The second latching portion is nested within the body structure and accessible through the release hole, while the first latching portion extends to engage the mounting member. This nested arrangement allows the complex function of secure latching to be contained within a simple external interface, maintaining both security and simplicity.
3Ease of operation
If tool-free operation is implemented, then ease of operation is improved, but the precision and control of latching member movement may be reduced
Solution Approach 1:
The latching member features asymmetric geometry where the first latching portion has a specific engagement shape that fits precisely with the mounting member, while the second latching portion has a different shape accessible through the release hole. This asymmetry ensures that manual pressure applied through the release hole is converted into precise, controlled movement of the entire latching member, maintaining manufacturing precision requirements while enabling tool-free operation.
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 secure, easy, and efficient mounting and demounting of the housing, allowing for convenient battery or SIM card replacement without complex tools, utilizing an elastic member for secure locking and tool-assisted unlocking.
Implementation Method 1
an elastic member mounted between the latching member and the body so that the latching member can remain at the first position in response to an elastic force of the elastic member

AI summary
A housing mounting mechanism (20) for a portable electronic device includes a body (22), a housing (26), a mounting member (28), and a latching member (24). The housing (26) is detachably mounted to the body (22). The mounting member (28) is connected to the housing (26) and has at least one mounting portion (40). The latching member (24) is movably mounted to the body (22) and has at least one latching portion (38). The at least one latching portion (38) can lock the at least one mounting portion (40) of the mounting member (28) when the latching member (24) is at a first position (P1) relative to the body (22). The at least one mounting portion (40) of the mounting member (28) can disengage from the at least one latching portion (38) after the latching member (24) is displaced to a second position (P2) from the first position (P1).
