Cable Take-Up Sleeve for Battery Swap Robot Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery swap robots face cable damage due to the use of drag chains for routing and traction, leading to potential safety hazards and reduced cable lifespan.
Innovation Solution
A take-up device with a spindle divided into sections, a rotatable take-up portion, and a sleeve with a restoring member, where the sleeve is wound around the spindle and connected to the power distribution cabinet and battery swap robot, allowing the cable to pass through and being stressed instead of the cable during operations, thereby preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drag chains are used for cable routing and traction in battery swap robots, then cable routing can be achieved, but the cables are likely to be damaged due to stretching and squeezing from frequent length changes
Solution Approach 1:
A take-up device is introduced as an intermediary mechanism between the cable and the battery swap robot. This device includes a reel that winds and unwinds the cable, and a restoring force generator that provides the necessary tension. The intermediary mechanism eliminates direct dragging and stretching of the cable, preventing damage while maintaining proper routing.
Solution Approach 2:
The take-up device is designed to automatically wind and unwind the cable based on the robot's position and movement, without requiring manual intervention. The restoring force generator automatically provides the necessary tension, making the system self-regulating and eliminating the need for external control of cable tension.
2Stability of the object's composition
If drag chains are used for cable routing in battery swap robots, then cable connection can be maintained, but frequent changes in cable length cause stretching and squeezing leading to potential safety hazards
Solution Approach 1:
The take-up device serves as a mediator that manages cable length changes. The reel mechanism smoothly winds and unwinds the cable, eliminating abrupt stretching and squeezing. The restoring force generator ensures continuous, controlled tension, preventing harmful forces from acting on the cable while maintaining stable connection.
Solution Approach 2:
The system transitions from a static drag chain configuration to a dynamic take-up device that actively adapts to the robot's movement. The reel rotates to accommodate length changes, and the restoring force generator dynamically adjusts tension, transforming the cable management system from passive to active and preventing damage from rigid constraints.
