Vehicle Sliding Console Dual-Duct Locking for Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sliding consoles suffer from inadequate fixation between moving and fixed parts, leading to shaking, noise, and poor positioning, especially when parked on slopes, due to gaps and reduced structural strength caused by dimensional scattering and assembly issues.
Innovation Solution
A vehicle sliding console design incorporating an additional assistant hook in the fixed part to enhance fixation, eliminating the need for traditional hooks, and utilizing a dual duct system with overlapping hooks to secure the moving and fixed parts, reducing the size of the lower plate and improving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional hook structure is used to fix the moving part to the fixed part, then the fixing strength is insufficient, but adding more hooks increases device complexity and weight
Solution Approach 1:
The hook structure is divided into two separate hooks: a first hook that selectively fixes the position of the first duct, and a second hook that restricts relative sliding between the first duct and second duct. This segmentation allows each hook to perform a specific fixing function, improving overall fixing strength while keeping individual hook structures simple
Solution Approach 2:
The assistant hook (second hook) serves multiple functions: it restricts relative sliding between ducts, provides additional fixing strength, and works in conjunction with the first hook to secure both moving and fixed parts. This multi-functionality improves fixing strength without proportionally increasing device complexity
2Weight of moving object
If the lower plate size is reduced to decrease weight and cost, then manufacturing cost and weight decrease, but fixing reliability deteriorates
Solution Approach 1:
The fixing function is segmented between two hooks instead of relying on a single large lower plate structure. The first hook handles position fixation while the second hook handles sliding restriction, allowing the lower plate to be smaller while maintaining fixing reliability through distributed fixing points
Solution Approach 2:
The assistant hook acts as an intermediary element that enhances fixing reliability without requiring a larger lower plate. It mediates between the ducts and the lower plate structure, providing additional fixing capability that allows reduction of the lower plate size while maintaining overall fixing reliability
3Ease of manufacture
If dimensional scattering and assembly variations occur in injection molded parts, then manufacturing cost remains the same, but structural strength for fixing and separating the hook decreases
Solution Approach 1:
The fixing function is divided between two hooks with distinct roles, which reduces the dimensional tolerance requirements for each individual hook compared to a single complex hook. This segmentation makes the structure more robust against dimensional scattering and assembly variations while maintaining ease of manufacture through standard injection molding processes
Solution Approach 2:
The design changes the fixing mechanism from relying on a single hook's dimensional precision to using two hooks with complementary functions. This parameter change (from one hook to two hooks) makes the system less sensitive to dimensional variations in injection molded parts while maintaining manufacturing feasibility
