Stepped Hook Arrangement for Secure Tool Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hook arrangements for attaching tools or containers to carrying elements are not stable enough, leading to potential damage or detachment during movement, especially when used in vehicles or transport boxes, due to insecure attachment and risk of hook damage.
Innovation Solution
A hook arrangement with a stepped design featuring a wider rear step and thinner front step, which securely engages with a receptacle's groove, preventing lateral movement and ensuring a fixed position, combined with support elements that guide and clamp the hook in place, providing a stable and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple hook is used for attaching tools or containers to carrying elements, then the attachment is easy to implement, but the stability and security of the attachment deteriorates, leading to potential damage or detachment during movement
Solution Approach 1:
The hook is divided into two distinct sections: a first hook section with a stepped design (wider rear step and thinner front step) for lateral engagement, and a second hook section for longitudinal engagement. This segmentation allows each section to perform its specific function optimally, providing both ease of attachment and secure retention.
Solution Approach 2:
Different parts of the hook have different geometric properties tailored to specific functions. The first hook section features a stepped configuration with varying widths to engage with groove walls laterally, while the second hook section has a different geometry for longitudinal engagement. This local differentiation of properties ensures both easy insertion and secure attachment.
2Reliability
If a secure hook arrangement is implemented to prevent movement during transport, then the reliability of attachment improves, but the device complexity increases due to the stepped design and multiple hook sections
Solution Approach 1:
The hook combines multiple functional sections (first hook section with stepped design for lateral engagement, second hook section for longitudinal engagement) into a single integrated element. This merging of functions into one component achieves secure attachment without requiring multiple separate parts, thus limiting the increase in device complexity.
Solution Approach 2:
The single hook element performs multiple functions: the first hook section engages with the groove walls to prevent lateral movement, while the second hook section engages to prevent longitudinal movement. This multi-functionality within a single component achieves reliable attachment without proportionally increasing complexity.
3Adaptability or versatility
If the hook arrangement allows frequent or repeated movement, then the adaptability to dynamic conditions improves, but the risk of hook damage or detachment increases
Solution Approach 1:
The hook sections are pre-configured with specific geometries (stepped first section, shaped second section) that are designed to engage with the carrying element's groove in predetermined ways. This preliminary design ensures that during frequent movement, the hook maintains proper engagement without requiring adjustment, preventing damage while adapting to dynamic conditions.
