Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spatially adjustable arms for medical instruments and devices face issues such as impaired mobility, limited vertical adjustability, increased complexity, and difficulty in adjustment, leading to impaired functional usability and potential health risks due to dirt accumulation in complex structures.
Innovation Solution
A spatially adjustable arm with an outer joint connected to a supporting system via an inner joint, featuring a balancing mechanism with a stabilizer and a compact design that ensures parallelism of joint axes, allowing for easy handling and stable anchoring, reduced weight, and fewer gaps for dirt accumulation, utilizing a sliding rod mechanism with adjustable nuts and compression springs for fine adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piston damper is used in the arm, then the arm achieves height balancing capability, but the mobility of the arm deteriorates
Solution Approach 1:
The patent removes the piston damper from the arm structure entirely, extracting the element that caused mobility restrictions while preserving height balancing capability through an alternative mechanism design
Solution Approach 2:
The arm is divided into multiple segments with independent rotational joints, allowing each segment to move freely without the constraint of a continuous piston damper, thereby improving mobility while maintaining balancing functionality
2Reliability
If a spring mechanism is mounted between a supporting ring and a guide, then the arm achieves balancing capability, but the arm lacks stabilizing elements resulting in impaired functional usability
Solution Approach 1:
The patent combines the spring mechanism with stabilizing elements into an integrated assembly, where the spring provides balancing force while the stabilizing elements maintain positional accuracy, resolving the contradiction between balancing capability and functional usability
3Adaptability or versatility
If multiple rotary supporting bushings and horizontal arms are used, then the arm achieves versatility in media transfer, but the vertical adjustability is limited
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that allow the arm to adapt its vertical position and configuration on demand, enabling both versatile media transfer and full vertical adjustability through movable and reconfigurable components
4Stability of the object's composition
If a robust structure with multiple parts is used, then the arm achieves stability, but the structure becomes more complex and heavier, requiring motorized adjustment
Solution Approach 1:
The patent merges multiple separate components into integrated assemblies, reducing the total number of parts while maintaining structural stability through carefully designed combined elements that perform multiple functions simultaneously
5Stability of the object's composition
If a gas spring is used to dampen the swinging arm movement, then the arm achieves movement control, but the arm becomes difficult to adjust
Solution Approach 1:
The patent removes the gas spring from the system, extracting the element that provided movement control but hindered adjustability, and replaces it with a simpler mechanism that allows easy manual adjustment while maintaining adequate movement control
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 solution enables easy handling, stable anchoring, reduced weight, lower material costs, and improved cleanliness, while maintaining high carrying capacity and ease of assembly/disassembly, addressing the limitations of prior art by providing a robust and reliable, adjustable arm for medical and industrial applications.
Implementation Method 1
The balancing mechanism further contains a rod, on which an adjustable nut is mounted that is engaged with a compression spring
Implementation Method 2
The use of the stabilizer secures the position of the vertical axis of the rotary connection element that is part of the outer joint in the vertical position without deflection
