Self-Adaptive Gap Compensation Mechanism for Precision Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gap compensation mechanisms in precision mechanics and optical systems suffer from concentrated stress and complex fabrication due to poor co-planar fixation, leading to deformity and additional processing requirements.
Innovation Solution
A self-adaptive gap compensation mechanism with a base seat, adjustment unit, and filler, providing three freedoms of altitude and two axial inclinations for posture adjustment, which eliminates concentrated stress and additional processing by using a resilient element, stacker, and adjustment element with a filler for structural reinforcement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional wedge insert and screw locking mechanism is used for gap compensation, then the workpiece can be fixed, but concentrated stress occurs due to poor co-planar extent of fixation planes
Solution Approach 1:
The adjustment mechanism is divided into multiple independent adjustment units, each capable of self-adaptive posture adjustment. This segmentation allows each unit to independently compensate for gaps and achieve close bonding state, distributing the stress rather than concentrating it at a single fixation point.
Solution Approach 2:
The invention introduces a resilient element that changes its physical state (compression/extension) to adapt to gap variations. By changing the parameter of the resilient element's deformation, the system achieves self-adaptive posture adjustment and close bonding state, eliminating concentrated stress.
2Productivity
If a conventional insertion mechanism is used for gap compensation, then assembly can be completed, but additional polishing processing is required for particular gaps
Solution Approach 1:
The adjustment unit is designed to perform self-adaptive posture adjustment automatically during assembly. The resilient element and adjustment elements work together to achieve close bonding state without requiring external intervention or additional polishing processing, making the system self-sufficient.
Solution Approach 2:
The invention transitions from a static insertion mechanism to a dynamic adjustment mechanism. The adjustment unit can dynamically adapt its posture through the resilient element's deformation, allowing the system to accommodate various gap geometries without additional processing.
3Reliability
If a conventional screw locking mechanism is used, then fixation is achieved, but the structure becomes complex and operational use becomes difficult
Solution Approach 1:
The invention merges the adjustment function and fixation function into a single integrated adjustment unit. The adjustment element and resilient element work together as one unified mechanism, eliminating the need for separate adjustment and locking components, thereby simplifying the overall structure.
Solution Approach 2:
The adjustment unit serves multiple functions simultaneously: it compensates for gaps, adjusts posture, achieves close bonding state, and provides fixation. This multi-functionality eliminates the need for multiple separate components, reducing structural complexity while maintaining reliability.
4Productivity
If conventional gap compensation is used, then assembly can be completed, but accurate posture adjustment is difficult to achieve
Solution Approach 1:
The invention replaces conventional mechanical screw-adjustment systems with a resilient element-based system. The resilient element's elastic deformation provides continuous, fine-grained adjustment capability, enabling accurate posture adjustment that is difficult to achieve with discrete mechanical threads.

AI summary
A gap compensation mechanism capable of self adaptive posture adjustment is disclosed, which comprises a base seat, having at least a fixation portion disposed thereon, the fixation portion having a flow path area disposed peripheral thereto; at least an adjustment unit, sleeved onto an outer rim of the fixation portion; and a filler, being filled within the flow path area. As such, a workpiece to be fixed may be disposed on a face of an adjustment unit. Further, the adjustment unit provides at least three freedoms for the altitude and two axial inclinations for self adaptively compensating a gap with any geometrical shapes and thus further adjusting the posture of the combined workpiece. After all the adjustments, a filler is filled to reinforce the structure and finally a fixation unit is employed for locking and fixing.
