Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling type X-ray apparatuses face high manufacturing costs and time due to complex post frame structures, excessive friction leading to energy inefficiency, and susceptibility to torsion and noise, along with significant tension load differences in spring balancers causing operational challenges and potential accidents.
Innovation Solution
A post frame design with an integral guide integrated into the main frame, a connecting bar with an insertion groove, and a bearing in line-contact configuration, along with a spring drum and coaxially arranged wire taper drums to reduce friction and tension load differences, enhancing durability and reducing maintenance costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the guide block is manufactured separately and fixed to the fixed frame or movable member by welding, then the guide block can be assembled, but the manufacturing process becomes complex and manufacturing time increases
Solution Approach 1:
The guide block is integrated directly into the movable member as a single piece, eliminating the need for separate manufacturing and welding processes. This merging of components reduces manufacturing complexity and time while maintaining the guide block's functional integrity.
2Reliability
If the guide block is in surface contact with the bearing, then the bearing can be supported, but friction increases and energy consumption increases
Solution Approach 1:
The patent replaces the conventional surface-contact mechanical system with a line-contact system where the bearing rotates along the guide block's edge. This substitution changes the contact geometry from area contact to line contact, significantly reducing friction and energy consumption while maintaining reliable bearing support.
3Strength
If the guide block has a box shape, then it provides structural support, but it causes torsion and noise during rotation
Solution Approach 1:
The guide block is designed with a curved surface instead of a flat box shape. This curvature allows the bearing to rotate smoothly along the guide block's edge, eliminating torsion and reducing noise generation while maintaining the structural support function.
4Ease of manufacture
If the guide block and bearing have weak wear resistance, then manufacturing is easier, but they are liable to break and require replacement
Solution Approach 1:
The patent applies heat treatment to the guide block to change its material properties, increasing hardness and wear resistance. This parameter change enhances the durability of the guide block-bearing interface without significantly complicating the manufacturing process, as heat treatment is a standard metallurgical process.
5Length of moving object
If the travel length of the X-ray tube is long, then the imaging coverage is extended, but the tension load difference of the spring balancer becomes substantial
Solution Approach 1:
The patent divides the single long wire into multiple wires wound on separate drums with different diameters. This segmentation allows the spring balancer to engage with wires of varying lengths, reducing the tension load difference across the spring balancer while maintaining extended travel capability through the coordinated rotation of multiple drums.
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
