Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle hooks with fixed mounting notches cause rewinding reels to disengage under impact or large forces, leading to instability and maintenance challenges.
Innovation Solution
A vehicle hook design featuring at least one closable mounting notch with an adjustable elastic member and guide notch to secure the rewinding reel, preventing disengagement by forming a closed notch after mounting, enhancing rotational stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If open mounting notches are used for the rewinding reel, then the reel can be easily installed and removed, but the reel will disengage under impact or large forces
Solution Approach 1:
The mounting notch transitions from a static open structure to a dynamic closable structure. The elastic member enables the notch to dynamically close after the reel is installed, transforming the engagement state from purely mechanical insertion to a secured closed state that prevents disengagement under load while maintaining ease of installation.
Solution Approach 2:
The mounting notch changes its geometric parameter (open to closed state) after installation. The elastic member allows the notch to deform and close, changing the engagement parameter from partial (open) to complete (closed), thereby increasing retention force while preserving easy installation through the initial open state.
2Reliability
If the mounting notch is made closable to prevent disengagement, then the reel stability improves, but the structure becomes more complex
Solution Approach 1:
The elastic member acts as a flexible element that enables the mounting notch to close dynamically. This flexible component adds minimal structural complexity compared to rigid locking mechanisms, achieving reliable engagement through elastic deformation and automatic closing action.
Solution Approach 2:
The elastic member provides self-service by automatically closing the mounting notch after the reel is installed. The elastic force naturally drives the notch to close without requiring additional actuation mechanisms, reducing overall structural complexity while ensuring reliable engagement.
3Reliability
If the elastic member is designed to overlap the reel after shifting, then the reel is securely constrained, but the manufacturing precision requirements increase
Solution Approach 1:
The mounting structure is segmented into distinct functional zones: the elastic member with its bearing end, the overlapping region, and the engagement area. This segmentation allows each zone to be optimized independently, with the bearing end positioned to shift and overlap the reel without requiring ultra-precise overall manufacturing, as long as local positioning tolerances are met.
Solution Approach 2:
High precision is required only at the local bearing end of the elastic member where it overlaps the reel, rather than throughout the entire mounting structure. The local quality principle allows the elastic member to have precise positioning at the critical overlap zone while tolerating less precision in other areas, balancing reliability with manufacturability.
