Modular Frame Bar for Military Mobile Device Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Military standard mobile electronic devices face challenges in altering their outer forms due to structural strength considerations, making it difficult to directly assemble expansion modules without redesigning the entire housing, leading to the need for separate designs for different utilization fields.
Innovation Solution
A mobile electronic device with a replaceable functional frame bar that includes a metal framework, back cover, and display panel, where the frame is locked and connected to all corners of the metal framework, allowing for the installation of various functional modules through a modular expansion box without altering the overall structure, enabling flexibility in design and usage across different fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the outer form of a military standard mobile electronic device is altered, then the device can meet different utilization requirements, but the structural strength requirements cannot be satisfied without redesigning the entire housing
Solution Approach 1:
The device is divided into a fixed housing structure and a replaceable functional frame bar. The functional frame bar can be detached and replaced with different modules to adapt to different utilization fields, while the main housing structure remains unchanged to maintain structural strength.
Solution Approach 2:
The functional frame bar is designed as a universal interface that can accommodate multiple different functional modules (expansion modules, communication modules, etc.). This allows a single housing design to support various functionalities by simply changing the frame bar module.
2Adaptability or versatility
If expansion modules are directly assembled onto the original structure, then functional versatility is improved, but the structural strength requirements cannot be met
Solution Approach 1:
The expansion functionality is segmented into a separate functional frame bar that attaches to the main housing. This separation allows the main housing to maintain its structural integrity while the functional frame bar provides expansion capabilities through modular attachments.
3Strength
If the overall structure is redesigned to meet structural strength requirements, then structural strength is improved, but development time and cost increase
Solution Approach 1:
By segmenting the device into a fixed housing and a replaceable functional frame bar, the invention avoids the need to redesign the entire structure for different functionalities. The housing is designed once to meet structural strength requirements, while the functional frame bar can be independently developed and replaced.
Solution Approach 2:
The universal housing design with standardized interface for the functional frame bar allows multiple functional modules to be accommodated without structural redesign, significantly reducing development time and cost for different utilization fields.
4Adaptability or versatility
If separate designs are developed for different utilization fields, then specific functional requirements are met, but design cost and complexity increase
Solution Approach 1:
A universal housing and functional frame bar interface is designed that can accommodate multiple different functional modules. This allows a single base design to serve multiple utilization fields by simply changing the functional frame bar, reducing overall design complexity.
Solution Approach 2:
The functional requirements for different utilization fields are segmented into separate replaceable frame bar modules. This modular approach allows each module to be optimized for its specific function while sharing the common housing structure, reducing the complexity of managing multiple complete designs.
