Vehicle Storage Lid Sealing With Deformable Volume Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a conflict between achieving reliable sealing and comfortable use of vehicle storage compartments, particularly in compartments accessible from the exterior, as high forces are required to close the lid due to trapped air acting as a spring against closure, risking deformation or damage.
Innovation Solution
A closing facilitation mechanism with a deformable element that compensates for the force required to close the lid by deforming to increase the storage volume, reducing the force needed and minimizing the risk of deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is closed directly without volume compensation, then the sealing arrangement is compressed to achieve reliable sealing, but the trapped air creates high opposing force that requires excessive closing force and risks lid deformation
Solution Approach 1:
The deformable element performs preliminary action by deforming in advance to increase the storage volume before the lid reaches the sealing position. This pre-compensation reduces the air pressure buildup that would otherwise occur during closure, thereby lowering the opposing force on the lid while still enabling reliable sealing when the lid contacts the sealing arrangement.
Solution Approach 2:
The system changes the physical parameter of storage volume dynamically during the closing process. The deformable element alters the volume parameter in real-time, expanding it before sealing to reduce pressure, which directly addresses the force contradiction by modifying the physical state of the trapped air without compromising sealing effectiveness.
2Reliability
If the lid is closed with high force to ensure sealing contact, then reliable sealing is achieved, but the lid risks deformation or damage due to the excessive force
Solution Approach 1:
The deformable element performs preliminary volume compensation before the lid reaches the sealing position, reducing the air pressure that would otherwise require high closing force. This preliminary action protects the lid from excessive force while still ensuring the sealing arrangement is properly compressed for reliable sealing.
Solution Approach 2:
The deformable element creates a preliminary counter-action by expanding the volume to reduce air pressure before the closing force is applied. This anti-action opposes the harmful effect of pressure buildup, thereby reducing the net force required for closure and protecting the lid from deformation or damage.
3Reliability
If the storage volume is reduced to compress the sealing arrangement, then sealing is achieved, but the trapped air creates over-pressure that increases the force required for closure
Solution Approach 1:
The deformable element performs preliminary volume expansion before the lid closure compresses the sealing arrangement. This pre-action compensates for the volume reduction that will occur during sealing, maintaining pressure balance and reducing the force required for closure while still achieving effective sealing.
Solution Approach 2:
The deformable element acts as an intermediary between the lid and the trapped air. It mediates the volume change by deforming to compensate for the air compression, thereby reducing the over-pressure effect and making lid closure easier without compromising sealing effectiveness.
