Solution Overview
Problem
Existing cable-arranging solutions for mobile devices face challenges such as cable twisting, cutting, and complex structures, which hinder easy handling and demonstration, particularly when extending or retracting power lines.
Innovation Solution
A cable-arranging assembly with a guide housing and withdrawal unit, featuring a rotatable guide unit with ball bearings and rollers, allowing the cable to rotate freely and reducing friction, coupled to the table with adjustable fixing bolts for secure attachment regardless of table thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cable is made extensible to allow easy handling of the mobile device, then the ease of operation is improved, but the cable may become twisted or cut during movement
Solution Approach 1:
The guide unit is designed to be rotatable within the guide housing, allowing it to dynamically adjust its orientation as the cable moves. This rotational capability enables the guide unit to follow the cable's movement direction, preventing twisting and cutting while maintaining cable integrity during extensible operations.
Solution Approach 2:
The guide unit acts as an intermediary between the cable and the guide housing. By introducing this intermediate rotatable component, the system allows the cable to move freely without direct constraint from the housing, thus preventing twisting and cutting while maintaining ease of operation.
2Ease of operation
If a cable-winding device is added to allow easy data transmission and charging, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The guide unit combines multiple functions into a single component: it guides the cable, allows rotation to prevent twisting, and works with the withdrawal unit for cable retraction. This merging of functions achieves cable management capabilities without requiring separate complex mechanisms for each function.
Solution Approach 2:
The guide housing and guide unit assembly serves multiple purposes: it guides the cable during extension, prevents twisting through rotation, and facilitates retraction through the withdrawal unit. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
3Stability of the object's composition
If the guide unit is fixed in position to maintain structural stability, then the stability is improved, but the cable cannot rotate freely causing twisting and cutting
Solution Approach 1:
The guide unit is designed with rotational freedom within the guide housing, transforming from a fixed static structure to a dynamic one. This allows the guide unit to rotate and follow the cable's movement, enabling free cable rotation while maintaining overall structural stability through the housing's fixed mounting.
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 prevents cable twisting and cutting, reduces frictional forces, and enhances usability by allowing smooth rotation and retraction of the cable, making it easier to handle and demonstrate mobile devices without resistance.
Implementation Method 1
the guide unit includes a fixed body, a rotatable body disposed within the fixed body, and a ball bearing allowing the rotatable body to rotate
Implementation Method 2
at least one of the guide unit and the withdrawal guide further includes a roller, whereby the cable can be more properly withdrawn or retracted

AI summary
A cable-arranging assembly coupled to a table such that a mobile device is displayed. A cable extends through a guide housing and a withdrawal unit configured such that the cable is connected to the mobile device. The guide housing and the withdrawal unit are coupled to the upper and lower portions of the table. A guide unit is rotatably disposed within the guide housing. The guide unit rotates along with rotation of the cable in the direction in which the cable rotates, thereby preventing the cable from being twisted or cut.
