Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric vehicle battery transportation container, as described in KR 10-2201715 B1, faces issues such as increased transportation costs due to the weight of the seat base, potential contamination during long-distance transport, damage from belt interference, and safety hazards during stacking operations.
Innovation Solution
A grid frame seat base with foldable shield sleeves, anti-slip parts, and corner support shafts that minimize weight, prevent contamination, and ensure secure stacking without finger injuries, using a ratchet system for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the seat base is manufactured as a plate shape with a closed upper surface to provide structural support, then the structural strength is improved, but the weight increases leading to higher transportation costs
Solution Approach 1:
The patent replaces the heavy plate-shaped closed upper surface with a lightweight mesh structure that provides sufficient structural support while significantly reducing weight. The mesh configuration maintains the necessary strength for battery support and belt tensioning while allowing material reduction through its open-work design.
Solution Approach 2:
The seat base incorporates a mesh structure with open spaces between the grid elements, creating a porous configuration that reduces material usage and weight while maintaining structural integrity through the distributed network of support members.
2Device complexity
If the electric vehicle battery is transported without a shield function to reduce device complexity, then the device complexity is reduced, but the battery is exposed to contamination by dust and foreign matters
Solution Approach 1:
The shield sleeve is designed to be foldable and movable, allowing it to be deployed when needed for protection and folded back when not required. This dynamic configuration provides contamination protection only during necessary periods, reducing device complexity and space requirements while maintaining protective capability when needed.
Solution Approach 2:
The foldable shield sleeve can be collapsed and stored within or alongside the seat base structure, allowing the protective function to be nested within the existing transportation container framework without adding significant external complexity.
3Strength
If a belt is tightened to fix the electric vehicle battery using a ratchet, then the fixing strength is improved, but interference occurs between the belt and the upper surface of the battery causing damage
Solution Approach 1:
The patent introduces an intermediary component (such as a protective pad or buffer element) between the belt and the battery upper surface. This intermediary distributes the contact pressure and prevents direct interference damage while maintaining the fixing strength provided by the ratchet and belt system.
4Device complexity
If only a belt is used to fix the electric vehicle battery to correspond to width changes, then the device complexity is reduced, but left-right slip cannot be prevented when the belt loosens
Solution Approach 1:
The anti-slip parts are designed as foldable components that can be deployed to provide lateral restraint and folded back when not needed. This dynamic deployment provides enhanced reliability against left-right slip only when necessary, maintaining device simplicity while improving security during critical phases of transport.
5Ease of operation
If corner support shafts are evenly coupled to support shaft insertion grooves to stack seat bases, then the stacking process is simplified, but the upper end portion of the shaft gets hooked on the lower opening causing delays and injuries
Solution Approach 1:
The patent introduces an asymmetric design where the corner support shaft and insertion groove have non-uniform configurations (such as tapered sections, offset positioning, or asymmetric engagement features). This asymmetric design guides the insertion process, prevents misalignment, and eliminates the hooking problem that causes delays and injuries during stacking operations.
