Utility Vehicle Storage Box Top Cover Sealing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional utility vehicles require high material costs and unstable sealing properties due to the large amount of sealing members needed to prevent water and dust from entering storage boxes, especially when the equipment is accessed through openings with fixed dimensions.
Innovation Solution
A utility vehicle design featuring a storage box with a top cover that allows for reduced clearance and flexible design, incorporating an intake port that supplies air from the outside, optionally with a filter member and wall portion to enhance sealing, reducing the need for extensive sealing members and improving sealing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening is covered with the bottom plate of the cargo bed or seat, then equipment can be accessed through the opening, but a large amount of sealing member is required to fill the clearance, increasing material cost and reducing sealing stability
Solution Approach 1:
Instead of covering the opening with the bottom plate of the cargo bed or seat as in conventional designs, the patent inverts the approach by using a top cover that closes the opening from above. This inversion allows the opening to be positioned at the top of the storage box, enabling equipment access while minimizing the clearance that needs to be filled with sealing members, thus reducing material cost and improving sealing stability.
Solution Approach 2:
The patent changes the spatial arrangement by moving the opening from the side or bottom to the top surface of the storage box. This dimensional change allows the opening to face upward toward the cargo bed or seat, enabling equipment access through the top cover while reducing the horizontal clearance that would otherwise require extensive sealing members.
2Ease of operation
If the opening is covered with the bottom plate of the cargo bed or seat, then equipment can be accessed through the opening, but the clearance cannot be decreased due to fixed position and shape constraints, leading to high material cost
Solution Approach 1:
The patent inverts the conventional approach by positioning the opening at the top of the storage box and covering it with a top cover, rather than having the bottom plate of the cargo bed or seat cover the opening. This inversion provides design flexibility, allowing the opening dimensions and position to be optimized for minimal clearance, thus reducing the amount of sealing material required and lowering manufacturing costs.
Solution Approach 2:
The patent changes the parameters of the opening configuration by relocating it to the top surface and adjusting its dimensions and orientation. This parameter change enables the opening to be sized and positioned optimally, minimizing the clearance that must be filled with sealing members and thereby reducing material cost while maintaining equipment accessibility.
3Reliability
If a large amount of sealing member is used to fill the clearance, then the opening can be sealed, but the sealing property becomes unstable
Solution Approach 1:
By inverting the conventional design and positioning the opening at the top of the storage box with a top cover, the patent minimizes the clearance that needs to be sealed. This reduces the amount of sealing member required from a large quantity to a minimal amount, while the concentrated sealing at the minimized clearance provides more stable and reliable sealing performance.
