Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting tubular elements with resilient retainers into flexible walls accessible from one side only are unreliable and inconvenient, particularly for less trained operators, due to manual orientation and contamination risks, and lack simplicity in operation.
Innovation Solution
A self-contained loading device with a bending mechanism automatically orients and folds retainers for secure insertion, using a loading tube and tool assembly that ensures precise alignment and secure attachment within the flexible wall, facilitating one-hand operation and reducing manual errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual orientation of retainers is used, then operator flexibility is maintained, but reliability and consistency of retainer alignment deteriorate
Solution Approach 1:
The loading device pre-positions and pre-orients the retainers in the correct alignment before insertion into the flexible wall. The retainers are held in a predetermined orientation within the loading device, ensuring consistent and reliable alignment during the insertion process, eliminating the need for manual orientation at the time of installation.
Solution Approach 2:
The loading device acts as an intermediary tool between the operator and the tubular element. It provides a controlled environment for holding and positioning the retainers, mediating the transfer of the tubular element into the flexible wall with precise orientation, thereby improving reliability without requiring complex manual manipulation.
2Object-affected harmful factors
If manual operations are performed, then device simplicity is maintained, but contamination risks and operational errors increase
Solution Approach 1:
The loading device is designed as a self-contained system that automatically maintains the cleanliness and proper orientation of the retainers throughout the insertion process. The device structure itself provides protection against contamination, and the mechanism automatically ensures correct positioning without requiring additional manual intervention or complex cleaning procedures.
Solution Approach 2:
The loading device prepares and protects the retainers in advance before insertion, holding them in a controlled environment that prevents contamination. The retainers are pre-positioned and protected within the loading device structure, eliminating exposure to contaminants during critical alignment operations.
3Reliability
If automated retainer folding is implemented, then insertion reliability is improved, but device complexity increases
Solution Approach 1:
The loading device incorporates a folding mechanism that pre-folds the retainers into their final insertion configuration before the tubular element is introduced. This preliminary folding action ensures that the retainers are already in the correct position and orientation, improving insertion security while using a relatively simple mechanical folding structure.
Solution Approach 2:
The loading device combines multiple functions into a single integrated structure: holding the tubular element, folding the retainers, maintaining orientation, and facilitating insertion. By merging these functions into one cohesive device, the overall complexity is managed while achieving high insertion reliability through coordinated action of all components.
4Productivity
If multiple manual steps are required, then operational control is maintained, but productivity and time efficiency decrease
Solution Approach 1:
The loading device merges multiple manual operations into a single integrated tool that performs holding, folding, orienting, and inserting functions simultaneously. This consolidation of operations into one device dramatically improves mounting speed and productivity, as the operator needs to perform only one insertion action rather than multiple separate manual steps.
Solution Approach 2:
The loading device performs all necessary preparation steps—folding retainers, positioning elements, ensuring correct orientation—in advance before the final insertion action. This preliminary preparation eliminates the need for multiple manual adjustment steps during installation, significantly improving productivity while maintaining ease of operation through a single insertion motion.
