Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for rod-like apparatuses are inefficient in positioning and removing long rods, and they lack mechanisms to securely store the rods without damage, leading to distortion and instability during storage and transportation.
Innovation Solution
A device with a body featuring notches and arc-shaped holding pawls that can be locked by positioning mechanisms, including springs and baffles, which securely hold the rods in place and allow for easy insertion and removal, using a guide element and locking bar for enhanced security and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cylindrical fixing mechanism with integrated locking mechanism is used to firmly fix rod-like apparatus, then the fixing reliability is improved, but the ease of operation for positioning and removing long rods deteriorates
Solution Approach 1:
The fixing device is divided into independent functional modules: a body with notches for rod insertion, arc-shaped holding pawls for clamping, positioning mechanisms with baffles for depth control, and a separate locking bar for security. This segmentation allows each component to perform its specific function efficiently, making the overall operation simpler despite the firm fixing capability.
Solution Approach 2:
The holding pawls act as intermediary elements between the rod-like apparatus and the body. These pawls can be independently actuated to clamp the rod at multiple notches, providing secure fixing without requiring the entire cylindrical mechanism to be engaged, thus simplifying the positioning and removal process for long rods.
2Productivity
If goods supporting means are vertically disposed to reduce distortion, then the storage efficiency is improved, but the stability deteriorates due to tendency to fall off
Solution Approach 1:
The holding pawls are pre-positioned at multiple notches along the body before the rod-like apparatus is inserted. When a rod is placed vertically, the pawls automatically engage at predetermined positions, preventing the rod from falling off without requiring additional positioning devices or complex mounting structures.
Solution Approach 2:
The holding pawls are nested within the body structure, with each pawl positioned within its corresponding notch. This nested arrangement allows the pawls to protrude slightly to engage the rod while remaining protected within the body, providing stable vertical storage without increasing the overall device footprint.
3Reliability
If multiple holding pawls are provided to securely hold rod-like apparatus, then the fixing reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple holding pawls are designed with identical arc-shaped structures and mounting mechanisms, allowing them to perform the same clamping function at different notches. This universality simplifies the overall design by repeating a proven successful component rather than creating complex specialized mechanisms for each holding position, thus maintaining reliability without proportionally increasing complexity.
