EV Battery Transport Container With Hook Fixing and Safe Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle battery transportation containers face issues such as damage to the battery surface due to belt interference, loosening of the belt leading to battery slip, and safety hazards during stacking due to uneven coupling of corner support shafts.
Innovation Solution
The container features battery fixing hooks, anti-slip parts, and adjustable corner support shafts to securely fix the battery, prevent slip, and facilitate safe stacking without damage or injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt is tightened to fix the electric vehicle battery to the seat base using a ratchet, then the battery can be secured to the seat base, but the belt interferes with the upper surface of the battery and may cause damage
Solution Approach 1:
The patent introduces battery fixing hooks as an intermediary component between the belt and the battery. The hooks engage with holes in the battery's lower bracket, allowing the belt to secure the battery without direct contact with the upper surface, thus preventing belt interference damage while maintaining fixation reliability
Solution Approach 2:
The fixation system is segmented into multiple components: the belt, the ratchet, and the battery fixing hooks. The hooks are divided into a body portion and a hook portion, with the hook portion specifically designed to engage with the battery's lower bracket holes, distributing the fixation function across separate elements to avoid surface damage
2Adaptability or versatility
If only a belt is used to fix the electric vehicle battery to correspond to changes in width, then the battery can be secured, but when the tightening strength decreases the belt loosens and left-right slip cannot be prevented
Solution Approach 1:
The fixation system uses multiple battery fixing hooks positioned at different locations (front, rear, left, right) rather than a single belt. This segmentation allows independent engagement with the battery's lower bracket at multiple points, preventing left-right slip while maintaining adaptability to width variations
Solution Approach 2:
The patent adds a vertical dimension to the fixation system by using hooks that extend downward to engage with the lower bracket holes, rather than relying solely on horizontal belt tension. This dimensional change provides additional restraint against left-right slip while preserving adaptability to battery shape changes
3Productivity
If corner support shafts or posts are used to stack seat bases, then stacking is enabled, but uneven coupling causes the upper end portion to hook on the lower opening, delaying stacking work and causing safety hazards
Solution Approach 1:
The corner support shafts are pre-formed with rounded upper end portions before the stacking operation. This preliminary shaping ensures that when the shafts are inserted into the support shaft insertion grooves, they smoothly pass through the lower openings without hooking, eliminating the need for manual adjustment and preventing pinching injuries
Solution Approach 2:
The patent changes the geometric parameter of the corner support shafts by rounding the upper end portions. This parameter modification reduces the likelihood of the shafts catching on the lower openings of the insertion grooves, enabling smooth and safe stacking operations while maintaining stacking efficiency
