Vehicle Footrest Storage Compartment Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing footrest devices for vehicles are difficult to install and require laborious access to the storage compartment, with increased manufacturing costs due to complex integration under the insulating layer and large wedge design.
Innovation Solution
A footrest with a support surface featuring connecting members that allow the storage compartment to be easily accessed and positioned between the support surface and the coating layer, including a pivot connection and locking means for easy assembly and disassembly, enabling the storage compartment to be closed or made accessible without removing the textile covering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the storage compartment is integrated under the insulating layer within the wedge structure, then the storage function is provided, but the installation becomes complex and access to the storage compartment requires removing the textile covering
Solution Approach 1:
The footrest is divided into separate components: the wedge structure providing support and the storage compartment as a distinct removable element. This segmentation allows the storage compartment to be accessed independently without removing the textile covering, while still providing integrated storage functionality.
Solution Approach 2:
A removable access panel or flap is introduced as an intermediary element between the textile covering and the storage compartment. This intermediary allows access to the storage compartment without requiring removal of the entire covering, thus maintaining aesthetic appearance while enabling easy access.
2Object-affected harmful factors
If the wedge is made of thermoplastic material with integrated insulating layer and textile coating, then sound insulation and aesthetic constraints are met, but manufacturing cost increases due to complex integration
Solution Approach 1:
The footrest components are segmented into separate manufacturable parts: the wedge structure, the insulating layer, and the textile coating can be produced separately and then assembled. This reduces manufacturing complexity and cost compared to integrated molding, while maintaining the required sound insulation properties.
Solution Approach 2:
The footrest uses composite construction combining different materials (thermoplastic wedge, acoustic foam insulating layer, and textile covering) that are assembled together. This allows each component to be optimized for its specific function and manufactured separately, reducing overall manufacturing cost while achieving required sound insulation and aesthetic properties.
3Volume of stationary object
If the wedge volume is increased to provide storage space, then storage capacity is improved, but manufacturing cost increases
Solution Approach 1:
The storage compartment is segmented as a separate removable component rather than being integrated into the main wedge structure. This allows the storage volume to be provided without increasing the size or complexity of the primary wedge, thus avoiding increased manufacturing costs for the main structure.
Solution Approach 2:
The storage compartment is designed to nest within the existing wedge structure or utilize the space between the wedge and the floor panel. This nesting approach provides additional storage volume without requiring an increase in the overall wedge volume, thereby avoiding increased manufacturing costs.

AI summary
The invention relates to a foot-rest (20) for a motor vehicle comprising a support surface (23) facing at least part of which a sound insulation mat can be extended, mounted on the floor (2) of the motor vehicle, comprising an insulating layer (3) interposed between the floor (2) and a coating layer (4) mounted on said insulating layer (3), said foot-rest further comprising a storage compartment (27). According to the invention, said support surface (23) comprises an inner face (26) intended to be positioned facing an outer face (41) of said coating layer (4), said inner face (26) being provided with links (261, 262) designed to support said storage compartment (27) in such a way that the inner volume of said storage compartment (27) extends between said inner face (26) of said support surface (23) and said outer face (41) of said coating layer (4).
