Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the display screen is rigidly mounted to the media chassis, then the display screen remains stable during normal operation, but the display screen cannot absorb impact forces during collisions

Engineering Contradiction:

Improvedisplay screen stabilityVSAvoidimpact damage

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The shock absorbing member is designed to be rigid during normal operation to maintain display screen stability, but becomes deformable during impact to absorb collision forces. This dynamic behavior allows the same component to provide both stability and impact protection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The shock absorbing member changes its mechanical properties from a rigid state during normal operation to a deformable state during impact. This parameter change allows the component to provide structural support when needed and absorb impact energy when colliding.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the display screen is allowed to pivot or tilt during impact, then the shock absorbing member can effectively absorb impact forces, but the display screen may contact sensitive electronic units behind the cockpit module causing damage

Engineering Contradiction:

Improveimpact force absorptionVSAvoiddisplay screen contact with electronic units

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The shock absorbing member is pre-positioned and pre-configured to counteract the pivot/tilt movement before it can cause harm. During impact, it actively pushes back against the display screen to prevent it from contacting electronic units behind the cockpit module.

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The shock absorbing member acts as an intermediary between the display screen and the electronic units. It absorbs the impact forces and prevents the display screen from directly contacting the electronic units, thereby protecting them from damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If a shock absorbing member is added to prevent display screen pivoting, then protection against impact is improved, but the device complexity increases

Engineering Contradiction:

Improveimpact protectionVSAvoidmedia assembly structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shock absorbing member is integrated with the media assembly structure, combining the shock absorption function with the existing mounting structure. This merging approach provides impact protection while minimizing the increase in overall device complexity.

Inventive Principle:

Principle #5Merging (Combining)
