Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun attachment mechanisms to trunnion devices face challenges in securely attaching and aligning the rotor assembly, particularly in transmitting substantial driving torques and maintaining precision alignment without causing torsional deflection or disturbing the trunnion assemblies during installation and removal.
Innovation Solution
A novel attachment mechanism featuring a bracket, block, and polygonal terminus with bolts and fasteners that securely clamp the rotor assembly to the trunnion shaft, ensuring self-centering and repeatable alignment through a recess and notch configuration, allowing for easy installation and removal without disturbing the trunnion assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional gun attachment mechanisms are used to securely attach the rotor assembly to the trunnion shaft, then the attachment strength is improved, but the alignment precision deteriorates due to torsional deflection
Solution Approach 1:
The attachment mechanism is divided into distinct functional segments: the bracket for positioning, the block for clamping, the polygonal terminus for anti-rotation, and the bolts for fastening. This segmentation allows each component to perform its specific function optimally without interfering with others, maintaining both strength and precision independently.
Solution Approach 2:
The polygonal terminus acts as an intermediary element between the bracket and block, providing a positive anti-rotation feature that prevents misalignment. This intermediary component transfers and maintains precise alignment while the bolts apply clamping force, decoupling the strength and precision functions.
2Power
If conventional attachment mechanisms are used to transmit substantial driving torques, then the torque transmission capability is improved, but the device complexity increases due to additional alignment and stabilization components
Solution Approach 1:
The bracket and block are merged into a single integrated clamping assembly that performs both positioning and torque transmission functions. The polygonal terminus is integrated directly onto the trunnion shaft, eliminating the need for separate anti-rotation components. This merging reduces device complexity while maintaining torque transmission capability.
Solution Approach 2:
The bracket serves multiple functions: it provides structural support, establishes precise alignment, and transmits torque. The block simultaneously clamps the terminus and distributes clamping forces. This multi-functionality reduces the number of separate components needed, simplifying the overall device while handling substantial torques.
3Stability of the object's composition
If conventional attachment mechanisms are used to maintain precision alignment, then the alignment stability is improved, but the ease of operation deteriorates due to difficulty in installation and removal without disturbing trunnion assemblies
Solution Approach 1:
The bracket and block are pre-positioned in the correct alignment configuration before the trunnion shaft is installed. The polygonal terminus is pre-formed on the shaft with precise geometry. This preliminary preparation ensures that when components are assembled, alignment is automatically established without requiring complex adjustment procedures during installation or removal.
Solution Approach 2:
The attachment mechanism transitions from a static, permanently fixed design to a dynamic, reversible system. The bolts provide controlled clamping force that can be easily adjusted or released, allowing the rotor assembly to be installed and removed without disturbing the trunnion assemblies. The flexibility to dynamically adjust clamping force maintains alignment stability while improving operability.

AI summary
An attachment mechanism is provided for connecting a trunnion shaft to a pivoting platform. The mechanism includes a bracket, a block, a polygonal terminus attached to the trunnion shaft, a pair of bolts and fasteners. The bracket has a center recess and flanking surfaces parallel to the pivoting platform. The block has a cutout notch. The polygonal terminus inserts into a gap formed between the recess and the notch. The pair of bolts extends through the bracket and the terminus, and inserts into the block. The plurality of fasteners attaches the bracket at the facing surfaces to the pivoting platform.
