Cantilever Hydraulic Slider Structure for Stable Bolt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hydraulic system of a cantilever device is complex and costly due to unnecessary friction, noise, and manufacturing complications, primarily caused by the design of the adjustment bolt and slider, which results in unstable operation and increased production costs.
Innovation Solution
The hydraulic system incorporates an end cap with a securing groove and an adjustment brace featuring track slots, along with a slider design that minimizes horizontal movement and eliminates the need for additional processing on the adjustment bolt, allowing for stable axial movement and reduced manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the adjustment bolt end is abutted against the top surface of the bottom wall and the bolt shoulder external diameter is made larger than the bolt head external diameter, then the adjustment bolt is limited within the end cap, but the rotation becomes less smooth and manufacturing cost increases
Solution Approach 1:
The invention extracts the adjustment bolt from the conventional abutted design and repositions it to pass through the through hole of the end cap, allowing the end to extend outward. This eliminates the need for abutting surfaces and large bolt shoulders, enabling smooth rotation while maintaining positioning stability through the through-hole configuration.
Solution Approach 2:
Instead of limiting the adjustment bolt within the end cap by abutting surfaces (conventional approach), the invention inverts the approach by having the bolt pass through the end cap with the end extending outward. This inversion eliminates friction from abutting surfaces while maintaining functional stability.
2Device complexity
If the slider is allowed to move freely between the side walls, then the assembly is simple, but the slider shakes and produces noise during operation
Solution Approach 1:
The invention introduces an intermediary component (the adjustment brace with track slots) between the slider and the side walls. This intermediary guides the slider's movement along defined track slots, preventing lateral shaking and noise while maintaining the simplicity of the overall assembly through the integrated track slot design.
3Object-generated harmful factors
If additional processing is applied to the adjustment bolt end to obtain a smooth surface, then friction is reduced, but manufacturing complexity and cost increase
Solution Approach 1:
The invention extracts the adjustment bolt from the abutted configuration and repositions it to pass through the through hole, eliminating the need for smooth surface processing on the bolt end. The bolt simply passes through the through hole without requiring friction-reducing surface treatments, thereby simplifying manufacturing while maintaining operational smoothness.
4Stability of the object's composition
If the end cap design includes multiple walls and grooves for securing the adjustment bolt, then the bolt is securely limited, but the end cap structure becomes complex and costly
Solution Approach 1:
The invention extracts the adjustment bolt securing mechanism from the complex multi-wall and groove design and simplifies it to a through-hole configuration. The adjustment bolt passes through the through hole of the end cap, which is secured to the top support, providing stable positioning without requiring multiple walls, grooves, or additional securing features.
