Holding Tray for SIM and Memory Module Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack effective mechanisms to securely hide and manage SIM cards and memory modules, such as SD cards, which can lead to issues like water ingress, reduced antenna space, and cosmetic design impacts when additional covers are used for protection.
Innovation Solution
A holding tray system with an external control mechanism that secures SIMs and memory modules inside the device, allowing for easy access while hiding them from external view, and can be configured as a single or multi-module tray, using push-push connectors or stand-alone external controls to eliminate entry points and prevent liquid ingress without additional cosmetic impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If SIM cards and memory modules are exposed in electronic devices, then accessibility is improved, but water ingress risk increases and cosmetic design is impacted
Solution Approach 1:
A holding tray is introduced as an intermediary component between the SIM/memory module and the external environment. The tray provides a protective interface that allows user access while shielding the components from water ingress and cosmetic damage.
Solution Approach 2:
The SIM card and memory module are nested within the holding tray, which itself is nested within the electronic device housing. This nested structure provides multiple layers of protection while maintaining organized accessibility.
2Ease of operation
If SIM cards and memory modules are exposed, then accessibility is improved, but antenna space is reduced
Solution Approach 1:
The device interior is segmented into distinct functional zones: the holding tray area for SIM and memory module access, and the antenna area for wireless communication. This segmentation allows both functions to coexist without interfering with each other's space requirements.
Solution Approach 2:
The holding tray utilizes vertical space and three-dimensional positioning within the device housing, allowing SIM and memory module access without occupying horizontal antenna space. The tray can be positioned in unused volumetric space rather than competing for surface area.
3Ease of manufacture
If traditional exposed mounting is used, then manufacturing simplicity is maintained, but design flexibility is reduced
Solution Approach 1:
The holding tray serves multiple functions simultaneously: it provides mechanical retention for SIM and memory modules, enables tool-less access for users, protects components from environmental damage, and allows flexible positioning within the device housing. This multi-functionality achieves design versatility without significantly complicating manufacturing.

AI summary
An apparatus for securing a memory module or SIM within an electronic device includes an external control (such as a volume control, camera button, or power button) that hides the memory module and/or SIM. When attached to the electronic device, the external control is disposed at the entrance of a cavity in which the memory module and/or SIM is located. The external control may be attached to a tray that holds one or more SIM cards and/or SD cards.
