Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AVN devices are inefficient due to integrated units requiring full replacement when only some components need upgrading, and they lack effective heat dissipation for high computational loads.
Innovation Solution
The AVN device is divided into a detachable replaceable portion and a fixed portion, with a conduction module facilitating heat exchange between them, using a thermally conductive sheet and a fan for efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the AVN device is manufactured as an integrated built-in unit, then the internal space of the vehicle can be efficiently utilized, but the replacement of the AVN device becomes inconvenient and requires full device replacement even when only some components need upgrading
Solution Approach 1:
The AVN device is divided into a fixed housing unit that remains installed in the vehicle and a replaceable second housing unit containing components with shorter replacement cycles. This segmentation allows the replaceable portion to be easily detached and replaced without affecting the fixed portion, thereby maintaining efficient space utilization while enabling convenient component upgrading.
2Ease of manufacture
If the AVN device is manufactured as an integrated unit, then manufacturing is simplified, but inefficiency occurs when the entire device must be replaced instead of only replacing specific elements with shorter replacement cycles
Solution Approach 1:
The device is segmented into a fixed housing and a replaceable second housing containing components subject to technological obsolescence. This allows manufacturers to produce standardized replaceable units that can be independently manufactured and upgraded, improving resource utilization by replacing only the necessary components rather than the entire device.
Solution Approach 2:
The replaceable second housing containing components with shorter replacement cycles is designed to be detached and replaced when those components become obsolete. This allows the fixed housing and other components to be recovered and reused, reducing waste and improving overall resource utilization efficiency.
3Adaptability or versatility
If the AVN device performs complex functions with high computational loads, then functionality is enhanced, but internal heat generation increases requiring effective heat dissipation structures
Solution Approach 1:
A conduction module is introduced as an intermediary between the replaceable second housing and the fixed first housing. This conduction module facilitates heat transfer from the high-heat-generating components in the second housing to the first housing, which has better heat dissipation capabilities, thereby enabling effective thermal management while maintaining complex functionality.
