Solution Overview
Problem
Existing display carrying devices in vehicles are rigid and fail to provide adequate protection against head impacts while maintaining effective heat conduction, leading to potential head injuries during accidents.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If rigid heat conducting structures are used to conduct heat from the display, then heat conduction efficiency is improved, but protection properties against head impacts deteriorate
Solution Approach 1:
The force absorbing portion is segmented into multiple wall elements (first wall element, second wall element, third wall element) that form hollow spaces between them. This segmentation allows the structure to deform in a controlled manner during impact while maintaining heat conduction pathways through the wall elements themselves.
Solution Approach 2:
The wall elements are designed with specific geometric parameters (oblique extension angles, hollow space configurations) that enable them to change their deformation characteristics based on impact conditions. The parameters are optimized to provide both heat conduction capability and impact energy absorption through controlled deformation.
2Object-affected harmful factors
If deformable wall elements are used to absorb impact energy, then protection properties against head impacts are improved, but heat conduction capability may deteriorate
Solution Approach 1:
The force absorbing portion combines deformable wall elements with hollow spaces in a composite structure. The wall elements serve as heat conduction pathways while the hollow spaces provide energy absorption capacity. This composite approach allows simultaneous achievement of both heat conduction and impact protection functions.
Solution Approach 2:
The wall elements serve multiple functions: they conduct heat from the display device, provide structural support, and absorb impact energy through controlled deformation. The hollow spaces between wall elements contribute to both impact absorption and potentially to cooling airflow, demonstrating multi-functionality that resolves the contradiction between heat conduction and impact protection.
3Stability of the object's composition
If rigid structures are used to maintain structural integrity, then structural stability is improved, but energy absorption during impact deteriorates
Solution Approach 1:
The force absorbing portion transitions from a static rigid structure to a dynamic deformable structure during impact. The wall elements are designed to deform in a controlled sequence, changing the structural configuration from stable to energy-absorbing state, which resolves the contradiction between maintaining structural integrity and absorbing impact energy.
Solution Approach 2:
The hollow spaces between the wall elements are pre-configured to provide cushioning effect before impact occurs. During normal operation, the structure maintains its integrity, but the pre-designed hollow spaces are ready to collapse and absorb energy when impact occurs, providing beforehand cushioning that resolves the contradiction between structural stability and energy absorption.
