Solution Overview
Problem
The limited space utilization in existing mobile phones hinders the integration of additional devices, restricting the diversification of mobile phone functions due to low space efficiency.
Innovation Solution
An electronic assembly is designed with a compact arrangement of components such as a receiver, flashlight, first circuit board, second circuit board, and sensor, stacked in the thickness direction, utilizing flexible circuit boards and a support frame to minimize space occupancy, allowing for higher space utilization and reduced size, enabling more devices to be integrated within the same space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional device arrangement is used in mobile phones, then device functionality can be maintained, but space utilization is low and available space is wasted
Solution Approach 1:
The patent transitions from traditional planar arrangement of electronic components to a three-dimensional stacked configuration. Multiple circuit boards (first circuit board, second circuit board) and components (receiver, flashlight, sensor) are arranged vertically in the thickness direction, utilizing the Z-dimension to increase space utilization while maintaining all necessary device functions.
Solution Approach 2:
The patent implements a nested arrangement where components are stacked within each other's spatial footprint. The receiver, flashlight, and sensor are positioned on different circuit boards at different heights, with each component's projection overlapping others in the planar view, effectively nesting multiple functional elements within a compact vertical space.
2Adaptability or versatility
If more devices are integrated into mobile phones to achieve diversified functions, then functionality diversification is improved, but the small available space makes it difficult to add new devices
Solution Approach 1:
By arranging multiple functional devices (receiver, flashlight, sensor, circuit boards) in the vertical thickness direction rather than spreading them out horizontally, the patent enables integration of more devices within the same device envelope, directly addressing the space constraint while achieving functionality diversification.
Solution Approach 2:
The patent divides the electronic device into multiple discrete functional modules mounted on separate circuit boards (first circuit board with receiver, second circuit board with flashlight and sensor). This segmentation allows each module to be independently positioned in the vertical stack, optimizing space utilization while maintaining all functions.
