Storage Box Seal Centering Structure for Misalignment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In storage box seal structures, misalignment of seal members and projections due to deformation or hinge looseness can degrade sealability, leading to ineffective sealing.
Innovation Solution
A centering structure with first and second ribs and guide portions is implemented to guide the opening and closing of the lid member, ensuring proper alignment and contact between the seal member and projection, enhancing sealability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a seal member and projection are used for sealing, then sealing function is achieved, but misalignment due to deformation or hinge looseness degrades sealability
Solution Approach 1:
The centering structure performs preliminary positioning of the seal member and projection before the sealing contact is made. By guiding the opening and closing motion through the first and second ribs, the seal components are pre-aligned in their correct positions, preventing misalignment issues that would otherwise occur due to deformation or hinge looseness.
Solution Approach 2:
The centering structure acts as an intermediary mechanism between the lid member and the seal components. It mediates the opening and closing motion, ensuring that the seal member and projection maintain proper alignment throughout the movement, thereby protecting the sealing function from degradation.
2Stability of the object's composition
If the seal member is integrally foam-formed in the recess, then the seal member is prevented from loosening or coming off, but positioning accuracy may be compromised
Solution Approach 1:
The centering structure is divided into separate components: the first rib and second rib that project from the recess, and the guide portion that is separate from both. This segmentation allows the seal member to remain stable in the recess while the guide portion provides precise positioning guidance during operation, resolving the conflict between stability and positioning accuracy.

AI summary
A storage box seal structure includes a recess, a seal member provided in the recess, and a projection that comes into contact with the seal member for sealing, and has, at an opening, a centering structure for guiding opening and closing of a lid member. The centering structure includes a first rib and a second rib projecting from opposite edges of the recess, and a guide portion that guides at least one of the first rib and the second rib at opening and closing.
