Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyor systems face operational challenges due to relative movement between roller shafts and motorized rollers, leading to instability and potential misalignment, which affects the smooth operation and efficiency of material handling processes.
Innovation Solution
An axle lock assembly comprising a first and second plate with a bushing mechanism that creates lateral forces to securely hold roller shafts in place, preventing rotation and ensuring stability during motorized roller operation, using guiding features and geometrical shapes to accommodate various configurations of roller shafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If roller shafts are allowed to rotate freely on conveyor rollers, then ease of installation and removal is improved, but relative movement between shafts and rollers causes instability and misalignment
Solution Approach 1:
The axle lock assembly uses a dynamic locking mechanism where the locking lever can be easily moved between locked and unlocked positions. The spring-loaded design allows the lever to automatically engage with the roller shaft, providing stable fixation during operation while remaining easily removable when needed, thus resolving the contradiction between ease of operation and stability.
Solution Approach 2:
The locking lever acts as an intermediary component between the axle lock assembly and the roller shaft. It provides a simple interface for operation (easy to engage/disengage) while simultaneously ensuring stable connection when locked, bridging the gap between ease of operation and operational stability.
2Device complexity
If conventional fixation methods are used for roller shafts, then device complexity is reduced, but relative movement leads to operational disruptions and reduced productivity
Solution Approach 1:
The axle lock assembly is segmented into distinct functional components: the locking lever for operation, the spring mechanism for automatic engagement, and the mounting structure for fixation. This segmentation allows each component to perform its specific function efficiently, providing reliable shaft fixation that prevents operational disruptions while maintaining reasonable complexity through modular design.
Solution Approach 2:
The spring-loaded locking lever automatically engages with the roller shaft when installed, providing self-service fixation without requiring additional tools or complex adjustment mechanisms. This automatic engagement ensures stable shaft positioning that prevents operational disruptions, thereby improving productivity while keeping the device complexity low.
3Stability of the object's composition
If roller shafts are securely locked in place, then stability and alignment are improved, but device complexity increases due to additional locking components
Solution Approach 1:
The essential stabilizing function is extracted and concentrated in the single locking lever component, which when engaged, provides sufficient stabilization for the roller shaft. By taking out only the necessary locking action rather than using a complex multi-component system, the design achieves stable shaft alignment while minimizing the increase in device complexity.
Solution Approach 2:
The locking mechanism applies stabilization locally at the critical interface between the roller shaft and the axle lock assembly. The spring-loaded lever provides concentrated locking force exactly where needed to prevent relative movement, achieving stable alignment without requiring complex stabilization throughout the entire conveyor system.

AI summary
Various embodiments illustrated herein disclose an axle lock assembly comprising a first plate with a first aperture, a second plate with a second aperture, a shaft, wherein the shaft is inserted through the first aperture and the second aperture and a bush. When the hushing is in contact with the first plate and the second plate, the bush creates a lateral force to move the first plate and the second plate in opposite directions to secure the shaft.
