Vehicular Door Speaker Placement for Storage Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicular door structures face challenges in maximizing storage capacity due to the placement of speaker grilles, which often interfere with the storage pocket, limiting its size.
Innovation Solution
The vehicular door structure positions the speaker above the storage part and near the central part in the up-down direction, allowing for increased storage capacity without obstructing the storage area and optimizing the placement to suppress vibrations and water ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the speaker grille is disposed horizontally at the same height as the storage pocket, then the speaker can be integrated into the door structure, but the storage capacity of the storage pocket is limited due to interference from the speaker grille
Solution Approach 1:
The speaker is repositioned from a horizontal arrangement at the same height as the storage pocket to a vertical arrangement above the storage pocket. This dimensional change in the up-down direction eliminates spatial interference between the speaker grille and the storage pocket, allowing the storage pocket to extend horizontally without obstruction while the speaker maintains its functional position near the central part of the door in the up-down direction
2Quantity of substance
If the speaker is positioned above the storage part near the central part in the up-down direction, then storage capacity is increased, but the structural configuration becomes more complex
Solution Approach 1:
The door structure is segmented into distinct functional zones: the speaker is positioned in the upper central region while the storage pocket occupies the lower region. This segmentation allows each component to be optimized independently for its specific function while maintaining overall structural integrity and simplifying the design of each individual component

AI summary
A vehicular door structure has a side door adapted to open and close an opening of a vehicle body, and the side door includes a door storage part having a storage area, and a door speaker. The door speaker is located above the door storage part in a virtual up-down direction and disposed near a central part in the up-down direction of the side door.
