Universal Platform Clamping With Elastic Force Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal platforms face issues with maintaining the clamping force between the bottom base and the ball head due to environmental temperature variations and material aging, leading to loosening and instability in positioning and angle adjustment.
Innovation Solution
A universal platform design that incorporates a fixed base, a rotating base, locking members, and elastic members, where the elastic members provide a compensatory force to maintain the clamping force even as the material ages or temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clamping force of the bottom base on the ball head is increased to prevent loosening due to aging and temperature variations, then the stability and positioning accuracy are improved, but the manufacturing precision requirements become extremely high and labor cost increases
Solution Approach 1:
The patent introduces an elastic member that provides dynamic clamping force through elastic deformation. The elastic member can automatically adjust and compensate for dimensional changes in the bottom base due to aging or temperature variations, maintaining stable clamping force without requiring extremely high manufacturing precision of the bottom base.
Solution Approach 2:
The patent changes the clamping force generation mechanism from static (relying solely on bottom base dimensions) to dynamic (utilizing elastic deformation of the elastic member). This parameter change allows the system to maintain reliable clamping force while reducing the stringency of manufacturing precision requirements for the bottom base.
2Reliability
If a locking method such as a screw is used to increase the clamping force, then the clamping force is improved, but the excess driving force during locking can easily damage the thread of the screw, needle of the head of the screw, and locking part
Solution Approach 1:
The patent replaces the screw-based mechanical locking system with an elastic member-based clamping system. This substitution eliminates the thread and needle components that are susceptible to damage from excess driving force, while still achieving reliable clamping force through elastic deformation of the elastic member.
Solution Approach 2:
The elastic member provides self-adjusting clamping force through its elastic properties. The system automatically maintains appropriate clamping force without requiring manual adjustment or risking over-tightening, as the elastic member naturally limits the force applied to the ball head based on its material properties and deformation characteristics.
3Ease of manufacture
If the bottom base is made of plastic material for ease of manufacture, then the ease of manufacture is improved, but the clamping force is insufficient and loosening occurs due to aging
Solution Approach 1:
The patent creates a composite structure combining the plastic bottom base with an elastic member (which may be made of different material properties). This composite approach allows the bottom base to retain its manufacturing advantages from plastic material while the elastic member provides the necessary clamping force and compensates for the plastic material's tendency to loosen with aging.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The platform effectively stabilizes the position and deflection angle of the rotating base, preventing loosening and ensuring consistent angle adjustment, even under conditions of material aging and temperature variations.
Implementation Method 1
Through an elastic force provided by an elastic member, a fixed base is pressed against a rotating base to stabilize the position and the deflection angle of the rotating base in the fixed base.
Implementation Method 2
the elastic member may compensate for the clamping force lost by the fixed base after the material of the fixed base ages so as to prevent the rotating base from loosening from the fixed base
