Solution Overview
Problem
As electronic devices become slimmer, the limited internal space poses challenges in securing sufficient space for speaker resonance and heat dissipation, limiting audio fidelity and operational reliability.
Innovation Solution
A foldable housing structure that enlarges the resonance space by folding the front plate, creating a variable resonance space between the speaker and rear plate, and enhances heat dissipation by expanding the internal space between the front and rear plates, allowing for improved sound quality and heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the device is made slimmer, then the device becomes more compact and portable, but the internal space for speaker resonance and heat dissipation is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the resonance space variable rather than fixed. The resonance space can be dynamically adjusted between a first size when the housing is in a first configuration and a second size when the housing is in a second configuration. This allows the device to maintain a slim profile in normal use while expanding the resonance space when audio performance is needed.
Solution Approach 2:
The patent utilizes dimensionality change by transitioning the housing between different configurations (e.g., folded and unfolded states). This transformation in spatial arrangement creates additional internal volume for resonance without increasing the device's external footprint, effectively solving the contradiction between compactness and resonance space.
2Volume of moving object
If the device is made slimmer, then the device becomes more compact and portable, but the internal space for heat dissipation is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the internal space variable rather than fixed. The housing can dynamically transition between configurations that provide different internal volumes, allowing sufficient space for heat dissipation components when needed while maintaining a slim profile during normal operation.
3Manufacturing precision
If the resonance space is enlarged, then audio fidelity is improved, but the device complexity increases
Solution Approach 1:
The patent applies the universality principle by designing the housing structure to serve multiple functions simultaneously. The same foldable or transformable housing mechanism that changes the device configuration also adjusts the resonance space volume. This multi-functionality avoids adding separate mechanisms for resonance space adjustment, thereby limiting the increase in device complexity.
