Vehicle Storage Lid Bracket Assembly With Temporary Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of vehicle storage devices is challenging due to the large and heavy lid, which requires manual support during placement of brackets, and the limited space for assembly when attaching the coil spring and other members.
Innovation Solution
A storage device design with engaging and engaged portions on the bracket body and attaching surface, allowing temporary assembly and fixation, facilitating easy assembly by eliminating the need to support the lid's weight and securing space for work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lid is made large to provide sufficient storage coverage, then the storage capacity and coverage are improved, but the weight of the lid increases making assembly difficult
Solution Approach 1:
The bracket body is divided into multiple segments including left and right brackets, front and rear brackets, and intermediate brackets. These segmented brackets are distributed throughout the storage portion to provide structural support, allowing the lid to be large for storage capacity while the brackets bear the weight rather than requiring manual support during assembly.
2Ease of operation
If the brackets are placed in predetermined positions while supporting the lid weight, then the bracket positioning is achieved, but the assembly complexity and difficulty increase
Solution Approach 1:
The bracket bodies are designed with engaging portions that extend along the attaching surface portion, and the attaching surface portion includes engaged portions with openings to receive the engaging portions. This preliminary structural design allows the brackets to be temporarily fixed in predetermined positions without requiring manual support of the lid weight during placement, simplifying the assembly process.
3Ease of manufacture
If the coil spring and other members are attached after placing the brackets, then the assembly sequence is logical, but the space required for work cannot be secured
Solution Approach 1:
The bracket body is segmented into multiple sections (left/right brackets, front/rear brackets, intermediate brackets) that are distributed throughout the storage portion. This segmentation creates distributed work spaces, allowing the coil spring and other members to be attached at various locations without requiring a large centralized workspace, while still maintaining a logical assembly sequence.
4Reliability
If the brackets are pressed toward the storage portion against the coil spring biasing force, then the bracket fixation is achieved, but the assembly difficulty increases
Solution Approach 1:
The engaging portions of the bracket body extend along the attaching surface portion and are designed to fit into engaged portions with openings. This preliminary structural arrangement allows the brackets to be temporarily fixed in the correct positions before final assembly, eliminating the need to press brackets against the coil spring's biasing force during the positioning stage, thereby reducing assembly difficulty while maintaining fixation reliability.

AI summary
A vehicle storage device includes a storage portion that has an opening in its one face and is configured to store at least one thing therein, a bracket body fixed to an attaching surface portion, which is another face of the storage portion, a shaft member supported on the bracket body, a lid supported on the shaft member such that the lid can swing to open and close at least part of the opening of the storage portion, and a coil spring configured to bias the lid in an opening direction. The bracket body includes at least one engaging portion that extends along the attaching surface portion. The attaching surface portion includes at least one engaged portion that has an opening to receive the respective engaging portion.
