Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional line guiding structures in mechanical equipment are limited to planar guidance and cannot effectively manage the movement of rigid lines, which are prone to damage during three-dimensional movements.
Innovation Solution
A line guiding structure comprising a round guiding shaft, an elastic element, a linear bearing, and a wheel set that allows the line to slide freely and move three-dimensionally, using a fixing unit and pulleys with smooth surfaces to guide lines such as cables, air pipes, and oil pipes in mechanical equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tank chain or energy chain is used to guide lines, then the lines can be guided in a planar manner, but the structure cannot accommodate rigid lines that are difficult to bend and cannot achieve three-dimensional guidance
Solution Approach 1:
The patent transitions from planar guiding to three-dimensional guiding by introducing a vertical dimension. The linear bearing can move up and down along the round guiding shaft, while the wheel set moves horizontally along the bearing. This creates a three-degree-of-freedom system that accommodates complex spatial movements of rigid lines.
Solution Approach 2:
The patent employs dynamic components including a retractable spring that provides elastic support, a linear bearing that can freely move vertically, and a wheel set that rolls horizontally. These dynamic elements allow the guiding structure to adapt to varying positions and movements of mechanical parts while supporting rigid lines.
2Reliability
If conventional planar guiding structures are used, then the structure is simple, but rigid lines are prone to damage by bending during movements
Solution Approach 1:
By adding the vertical movement capability through the linear bearing on the round guiding shaft, the system provides three-dimensional guidance space. This allows rigid lines to move in multiple directions without excessive bending, thereby protecting line integrity while accommodating complex mechanical movements.
Solution Approach 2:
The wheel set acts as an intermediary between the rigid line and the guiding structure. The line passes through the slide hole of the wheel set, which rolls along the linear bearing. This intermediary mechanism reduces direct friction and bending stress on the rigid line while enabling smooth movement.
3Adaptability or versatility
If a round guiding shaft with linear bearing and wheel set is used for three-dimensional guidance, then rigid lines can move freely without bending damage, but the device complexity increases
Solution Approach 1:
The system uses dynamic components (retractable spring, linear bearing, rolling wheel set) that provide three-degree-of-freedom movement capability. The linear bearing moves vertically along the round guiding shaft while the wheel set rolls horizontally, creating a compact yet versatile three-dimensional guidance mechanism that balances complexity with functionality.
