Centered Bolt Pressing Assembly to Prevent Misalignment Loosening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressing devices face safety risks due to incorrect assembly and wear-related issues with releasable connecting means, leading to potential accidents and improper alignment during the pressing process.
Innovation Solution
A pressing device with a non-releasable securing element and centering elements that ensure correct alignment and fastening of components, preventing accidental loosening and ensuring secure assembly by using a bolt with a securing element and fastening element, where the centering element centers the securing element on the bolt, and the fastening element secures it in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable fasteners (screws, snap rings, circlips) are used to assemble pressing device components, then ease of assembly and disassembly is improved, but reliability deteriorates due to wear patterns, incorrect replacement, and potential part breakage during operation
Solution Approach 1:
The patent removes the detachable fastener elements (screws, snap rings, circlips) from the assembly system entirely. The pressing device components are designed to be permanently connected through direct mechanical joining, eliminating the need for removable fastening elements that cause wear and reliability issues.
Solution Approach 2:
The patent merges the support element and pressing element into a unified structure where the pressing element is directly integrated with the support element. This merging eliminates the interface requiring fasteners, thereby eliminating wear patterns and the risk of incorrect assembly associated with detachable connections.
2Productivity
If pressing device components are subjected to heavy stress during use, then productivity is improved, but object-generated harmful factors worsen due to safety risks from imprecise assembly and potential projectile fragmentation
Solution Approach 1:
The patent incorporates centering elements that pre-align the pressing element with the support element before the pressing operation begins. This preliminary alignment ensures precise positioning under stress, preventing misalignment-induced failures and projectile fragmentation during high-capacity pressing operations.
Solution Approach 2:
The centering elements act as intermediary components between the support element and pressing element. These mediators ensure precise alignment and positioning, distributing stresses evenly and preventing the harmful effects of imprecise assembly that could lead to safety hazards during heavy-duty pressing.
3Manufacturing precision
If considerable force is applied to align fasteners precisely during assembly, then manufacturing precision is improved, but ease of manufacture deteriorates due to the effort required
Solution Approach 1:
The centering elements are designed to automatically align the pressing element with the support element during assembly without requiring external forcing or precise manual positioning. The geometry of the centering elements self-guides the components into correct alignment, eliminating the need for considerable assembly force while maintaining high precision.
