Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a conventional camera lifting structure is used in a thin display device, then the camera can be lifted for operation, but the structure occupies excessive internal space and interferes with internal circuit components

Engineering Contradiction:
Improvespace occupied by camera lifting structureVSAvoidinterference with internal circuit components
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The patent transforms the traditional vertical lifting motion into a horizontal sliding motion along a rail bracket. The camera module moves along the first direction (horizontal) rather than the second direction (vertical), allowing the lifting structure to occupy less vertical space within the display device and avoid interference with internal circuit components while maintaining the camera's lifting functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs a dynamic mechanism where the camera module can switch between a first state (retracted) and a second state (extended) through sliding portions that move along the rail bracket. This dynamic design allows the camera to be positioned optimally during operation while minimizing space occupation when retracted, resolving the contradiction between operational capability and space utilization.

Inventive Principle:
Principle #15Dynamics

2Volume of moving object

If the camera lifting structure is reduced in dimension, then space utilization improves, but the stability and control of camera movement may deteriorate

Engineering Contradiction:
Improvedimension of camera lifting structureVSAvoidstability of camera movement
Core Design Contradiction:
Volume of moving objectVSStability of the object's composition

Solution Approach 1:

The patent introduces elastic elements as intermediary components between the sliding portions and the rail bracket. These elastic elements provide cushioning and stable support during the camera's sliding motion, ensuring controlled and stable movement while allowing the overall structure to maintain compact dimensions. The elastic elements act as mediators that maintain stability without requiring a larger structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent incorporates elastic elements that provide beforehand cushioning to the camera module during its movement. This cushioning mechanism ensures stable and controlled motion of the camera along the rail bracket, preventing instability that might result from the reduced dimensional structure while maintaining the compact design.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of manufacture

If the camera lifting structure uses traditional design, then it is simple to manufacture, but it causes electromagnetic interference and poor heat dissipation due to close distance to internal circuit components

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidelectromagnetic interference and heat dissipation
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

By changing the motion direction from vertical to horizontal, the patent repositions the camera module's trajectory away from internal circuit components. This dimensional change allows the camera to operate effectively while maintaining greater spatial separation from heat-generating and electromagnetic-emitting circuits, reducing harmful effects without significantly complicating the manufacturing process.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Volume of moving object

If sliding portions are added to enable horizontal movement, then space occupation is reduced, but the device complexity increases

Engineering Contradiction:
Improvespace occupied by lifting structureVSAvoidstructural complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the sliding portions, which simultaneously serve as movement mechanisms, support structures, and space-saving elements. By combining these functions into integrated components rather than separate parts, the patent achieves compact space occupation while controlling the increase in device complexity through functional integration.

Inventive Principle:
Principle #5Merging (Combining)
