Front Trunk Drainage and Noise-Reducing Through-Hole Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with front trunks, rainwater and external noise such as wind noise and tire noise enter the storage space, leading to an uncomfortable interior environment.
Innovation Solution
A front trunk design featuring a storing portion with a box shape that opens upward, including a bottom wall and side walls with a through hole that allows water drainage and noise absorption, utilizing sound-absorbing materials and a resonator configuration to reduce external noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is lifted up to be opened, then the storing space can be accessed, but rainwater may enter the storing space
Solution Approach 1:
The patent extracts the water drainage function from the storing space by providing a through hole that allows water to be discharged from the storing space to the outside, separating the storage function from water accumulation
Solution Approach 2:
The patent applies preliminary anti-action by pre-configuring the through hole in the bottom wall or side wall to prevent water accumulation before it becomes a harmful effect, countering the potential harm of rainwater entry
2Ease of operation
If the cover is configured not to cover the opening effectively, then the storing space is accessible, but rainwater is more likely to enter
Solution Approach 1:
The patent extracts the water drainage function by providing a through hole that allows water to be discharged from the storing space, separating the storage function from water accumulation
Solution Approach 2:
The through hole acts as an intermediary element that mediates between the storing space and the external environment, allowing water to pass through while maintaining the structural integrity of the front trunk
3Object-affected harmful factors
If noise reduction measures are added, then noise is reduced, but device complexity increases
Solution Approach 1:
The patent applies universality by making the through hole serve multiple functions: both water drainage and noise reduction, eliminating the need for separate structures for each function
Solution Approach 2:
The patent merges the water drainage function and noise reduction function into a single through hole structure, combining multiple functions into one element to reduce overall device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively drains water and reduces external noise, creating a more comfortable vehicular interior space by using the through hole for water drainage and sound absorption.
Implementation Method 1
a through hole that is included in one of the bottom wall and the side walls and through which the storing space is communicated with an outer space outside the storing portion
Implementation Method 2
utilizing sound-absorbing materials and a resonator configuration to reduce external noise
Implementation Method 3
utilizing sound-absorbing materials and a resonator configuration to reduce external noise
