Pedestal Bend Portion for Blower Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a blower is positioned adjacent to a battery in a vehicle, external forces can cause it to strike the battery, leading to potential damage.
Innovation Solution
A vehicle design featuring a pedestal with a bend portion that deforms to move the blower away from the battery, incorporating a first and second inclined area to ensure the blower is positioned off the battery unit, even under external force, and a protruding portion for added strength, allowing the blower and battery to be mounted as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the blower is placed at a position adjacent to the battery, then the blower can be positioned closer to the battery for efficient cooling, but the blower may strike the battery when external force is applied
Solution Approach 1:
The pedestal incorporates a bend portion that allows dynamic movement of the blower in response to external forces. When force is applied, the bend portion deforms to move the blower away from the battery, preventing collision while maintaining close positioning under normal conditions
Solution Approach 2:
The bend portion acts as a pre-designed cushioning element that absorbs external forces before they can transmit to the battery. The inclined areas provide progressive deformation resistance, cushioning the blower's movement to prevent sudden impacts
2Reliability
If the pedestal is made flexible to allow blower movement, then the blower can avoid striking the battery, but the pedestal strength may be compromised
Solution Approach 1:
The pedestal employs local quality variation through the bend portion with inclined areas. The bend portion has controlled flexibility for movement, while the protruding portion and other areas maintain high strength. This localized differentiation allows flexibility where needed and strength where required
Solution Approach 2:
The pedestal integrates multiple structural features (bend portion with inclined areas, protruding portion) that combine flexible and rigid characteristics. The composite structure achieves both movement capability and structural strength through integrated design
3Productivity
If the blower is positioned close to the battery, then the cooling efficiency is improved, but the risk of striking the battery under external force increases
Solution Approach 1:
The dynamic bend portion allows the blower to maintain close positioning to the battery for efficient cooling under normal conditions, while automatically moving away when external forces are applied, eliminating the harmful collision effect
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
Prevents the blower from striking the battery by relocating it through the deformation of the pedestal, ensuring the blower remains clear of the battery and supporting components, even when external forces are applied.
Implementation Method 1
a bend portion allowing movement of the blower to a position off the electric storage unit through deformation in response to an external force

AI summary
A vehicle has an electric storage unit having a plurality of electric storage elements and outputting energy for use in running of the vehicle, a blower placed closer to the exterior of a vehicle body relative to the electric storage unit and supplying the electric storage unit with air for adjusting the temperature of the electric storage element, and a pedestal supporting the blower. The pedestal has a bend portion allowing movement of the blower to a position off the electric storage unit through deformation in response to an external force.
