Solution Overview
Problem
Modern handheld electronic devices face challenges in integrating multiple subsystems such as touch-sensitive displays, wireless communications, cameras, and batteries into a compact and reliable form that can withstand daily use, while providing a wide range of functionalities.
Innovation Solution
The design incorporates a mobile phone enclosure with a front cover assembly, rear cover assembly, and a housing subassembly that includes a camera array and battery, with a charging coil for wireless charging, and uses a combination of metals like aluminum alloy for the core and titanium alloy for the cladding to enhance durability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple subsystems (cameras, battery, wireless charging) are integrated into a compact enclosure, then device functionality and versatility are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The housing is divided into multiple components including front cover assembly, rear cover assembly, and housing subassembly with distinct functional zones. The camera array is segmented into multiple cameras positioned in an interior cavity, and the charging coil is separately positioned between the rear cover and lower chassis section, allowing independent assembly and manufacturing of each subsystem.
Solution Approach 2:
The camera array is nested within the interior cavity defined by the housing subassembly, with cameras extending through the lower chassis section. The charging coil is nested between the rear cover and the second side of the lower chassis section, enabling compact integration of multiple subsystems within the enclosure without increasing overall device volume.
2Adaptability or versatility
If camera array and battery are positioned in the interior cavity, then device functionality is improved, but available space for other components is reduced
Solution Approach 1:
The camera array utilizes the depth dimension by extending cameras through the lower chassis section into the interior cavity, while the battery is positioned in the same cavity but coupled to the first side of the lower chassis section. The charging coil is positioned in a different spatial zone between the rear cover and second side of the lower chassis section, allowing multiple components to coexist in three-dimensional space without significant volume conflict.
3Strength
If the lower chassis section is welded to housing components, then structural strength and durability are improved, but manufacturing complexity increases
Solution Approach 1:
The lower chassis section is constructed from aluminum alloy providing structural strength, while the front cover assembly and rear cover assembly incorporate titanium alloy cladding portions bonded to aluminum alloy core portions. This composite material approach achieves high structural strength and durability while allowing modular manufacturing of different housing components that can be joined through welding and bonding processes.
