Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a reflective layer made of metal materials (silver or aluminum) is used to reflect light, then the display panel can save electric energy, but the manufacturing process becomes complex and requires continuous power for the handwriting touch module
Solution Approach 1:
The reflective layer is segmented into multiple micro-capsules, each containing a mixture of magnetic absorbing particles and non-magnetic reflecting particles. This segmentation allows the reflective layer to function without continuous power supply while simplifying the manufacturing process by eliminating the need for complex handwriting touch module power management systems.
Solution Approach 2:
The reflective layer uses a composite material system consisting of magnetic absorbing particles (with magnetic properties) and non-magnetic reflecting particles (with high reflectivity). This composite structure enables the layer to reflect light passively without requiring external power, thereby reducing energy consumption and manufacturing complexity.
2Adaptability or versatility
If a handwriting touch module is added to enable writing function, then the display becomes more versatile, but continuous power is required and manufacturing costs increase
Solution Approach 1:
The magnetic reflective layer serves itself by using the magnetic properties of the absorbing particles to respond to magnetic fields from writing tools. The layer automatically switches between display and writing modes without requiring external power control, enabling the handwriting function to be activated only when needed through magnetic field interaction.
Solution Approach 2:
The reflective layer changes its optical parameters (reflectivity and absorption) in response to magnetic field changes. When a magnetic writing tool approaches, the magnetic absorbing particles change their magnetic state, altering the layer's optical properties to enable writing mode, thereby providing versatility without continuous power consumption.
3Use of energy by stationary object
If micro-capsules containing magnetic absorbing particles and non-magnetic reflecting particles are used, then power consumption is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
Each micro-capsule is designed with local quality differentiation, containing both magnetic absorbing particles and non-magnetic reflecting particles in specific proportions. This local composition ensures that each capsule unit independently provides the desired optical and magnetic properties, reducing the need for high overall manufacturing precision while maintaining performance.
Solution Approach 2:
The magnetic absorbing particles within the micro-capsules can dynamically change their magnetic state in response to external magnetic fields. This dynamic property allows the particles to adjust their behavior based on operational conditions, compensating for variations in manufacturing precision and ensuring consistent performance across different capsules.
