Glass-Wiping Robot Cord Sheath to Prevent Handle Entanglement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The power cord of existing glass-wiping robots tends to wind around the handle during operation, leading to interference with the movement track, potential power outages, and safety risks due to its flexible mobile operating mode.
Innovation Solution
A power cord positioning sheath with a simple structure is integrated into the glass-wiping robot's housing, ensuring the power cord remains fixed and perpendicular to the surface, preventing it from winding around the handle or other protruding mechanisms by maintaining a height difference greater than or up to 5 mm with the protruding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the glass-wiping robot is designed with a flexible mobile operating mode, then the robot achieves high flexibility and ease of operation, but the power cord is likely to wind around the handle and interfere with movement
Solution Approach 1:
A power cord positioning sheath is introduced as an intermediary component between the power cord and the handle. The sheath guides and constrains the power cord along a predetermined path, preventing it from winding around the handle while allowing the robot to move flexibly. This mediator resolves the conflict between operational flexibility and power cord stability.
2Reliability
If the power cord positioning sheath height is made greater than the protruding mechanism, then the power cord is prevented from winding around the handle, but the device complexity increases
Solution Approach 1:
The power cord positioning sheath is designed as a thin-walled cylindrical structure that is relatively simple in form. This thin-film approach provides the necessary guiding function without adding significant structural complexity. The sheath's simple cylindrical design allows it to effectively prevent power cord winding while maintaining ease of manufacturing and integration.
3Ease of manufacture
If the power cord positioning sheath is designed with a simple structure, then the manufacturing cost is reduced, but the effectiveness in preventing power cord winding may be compromised
Solution Approach 1:
The positioning sheath's effectiveness is achieved through optimized dimensional parameters rather than complex structure. The sheath height is specifically designed to be greater than the handle height, and the cylindrical diameter is appropriately sized to contain the power cord. These parameter optimizations ensure reliable power cord containment while maintaining a simple, easy-to-manufacture structure.

AI summary
A glass-wiping robot comprising a glass-wiping robot housing (1), a power cord (2) extending outward through the housing (1), a protruding mechanism (3) provided on the housing (1) and protruding from the surface thereof, and a power cord positioning sheath (4) provided on the housing (1), where the power cord (2) passes through a central through-hole of the power cord positioning sheath (4) and is fixed. By providing the power cord positioning sheath (4), the glass-wiping robot ensures that the power cord (2) does not interfere with other parts on the surface of the machine body of the glass-wiping robot, prevents the power cord (2) from hanging downward and winding when the glass-wiping robot is working, provides a simplified structure, and greatly improves the operational safety of the glass-wiping robot.
