Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display module is miniaturized to improve aesthetics and portability, then the size of the module is reduced, but the layout of numerous connectors on the circuit board becomes more difficult and the control board is more prone to deformation and damage under vibration
Solution Approach 1:
The supporting component is divided into a main body and multiple independent fixing portions (first fixing portion, second fixing portion, third fixing portion) distributed at different locations. This segmentation allows each fixing portion to independently secure the control board, preventing deformation under vibration while maintaining a compact overall structure.
Solution Approach 2:
The fixing portions extend in the thickness direction (vertical dimension) of the display module, creating a three-dimensional fixation structure. This vertical dimensionality adds structural support without increasing the horizontal footprint, enabling miniaturization while improving vibration resistance.
2Volume of moving object
If the display module is miniaturized to improve aesthetics and portability, then the size of the module is reduced, but the layout of numerous connectors on the circuit board becomes more difficult
Solution Approach 1:
The fixing portions utilize the thickness direction to create a three-dimensional arrangement, allowing connectors to be distributed vertically and horizontally. This multi-dimensional layout approach accommodates numerous connectors within the limited horizontal space of a miniaturized module.
Solution Approach 2:
By dividing the supporting structure into multiple separate fixing portions positioned at different locations, the design creates organized zones for connector placement. This segmentation allows systematic arrangement of numerous connectors without increasing overall module size.
3Device complexity
If conventional fixation methods are used to secure the control board, then the structure is simple, but the control board deforms and damages under vigorous vibration and high temperature
Solution Approach 1:
The fixation structure is segmented into multiple independent fixing portions distributed at different locations on the supporting component. This segmentation provides multiple attachment points that collectively resist vibration and thermal stress, preventing control board deformation while maintaining reasonable structural simplicity.
Solution Approach 2:
Each fixing portion is strategically positioned at specific locations where vibration and thermal stress are most likely to cause deformation. By concentrating fixation strength at these critical locations, the design effectively resists environmental stresses without requiring complex fixation mechanisms throughout the entire structure.
