Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slider assemblies, particularly those with symmetrical dovetail connections, are prone to incorrect installation due to manufacturing tolerances and unsymmetrical tool setups, leading to potential damage during operation.
Innovation Solution
Implementing an unsymmetrical dovetail connection arrangement where the symmetry plane of the dovetail connection is offset from the tool center, with gliding plates positioned asymmetrically to prevent 180° misalignment and ensure correct assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a symmetrical dovetail connection is used for the slider assembly, then the manufacturing and assembly process is simplified, but the risk of incorrect installation (180° misalignment) increases due to manufacturing tolerances and unsymmetrical tool setups
Solution Approach 1:
The patent applies asymmetry by offsetting the symmetry plane of the dovetail connection from the tool center. The holding section formed as a dovetail has its symmetry plane (second symmetry plane S2) offset by a distance y from the first symmetry plane S1 that runs through the tool center. This asymmetric arrangement ensures that only one correct installation position is possible, preventing 180° misalignment while maintaining the simplicity of the dovetail connection structure.
2Stability of the object's composition
If the symmetry plane of the dovetail connection coincides with the tool center, then the force distribution appears balanced, but the gliding plates cannot prevent incorrect assembly orientations
Solution Approach 1:
The patent offsets the dovetail symmetry plane from the tool center, creating an asymmetric configuration where the holding section's symmetry plane (S2) is displaced by distance y from the tool center symmetry plane (S1). This asymmetry simultaneously achieves orientation control (preventing incorrect assembly) and maintains force distribution stability through the offset arrangement of gliding plates.
Solution Approach 2:
The patent introduces a positional offset in the lateral dimension (distance y perpendicular to the slider axis) to solve the orientation problem. By shifting the dovetail symmetry plane laterally from the tool center, the system adds a dimensional parameter that prevents rotational misalignment while the gliding plates maintain force distribution along the slider axis.
3Productivity
If manufacturing tolerances are present in symmetrical components, then mass production is feasible, but the accumulation of tolerances leads to incorrect installation and potential damage
Solution Approach 1:
The patent uses asymmetric offset of the dovetail symmetry plane to convert a precision problem into a tolerance-free design. The offset distance y creates a geometric constraint that is insensitive to manufacturing tolerances in the individual components, allowing mass production while ensuring correct installation accuracy through the inherent asymmetry of the configuration.
