Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for processing light guide plates are inefficient, as they can only process one plate at a time, leading to resource wastage and inefficiency in cutting and polishing.
Innovation Solution
A stack of light guide plates is created by reversing and laminating pairs of plates with varying incident side thicknesses and shapes, ensuring neat and flat alignment, allowing for batch processing and efficient cutting and polishing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If only one light guide plate is processed at a time, then the processing quality can be maintained, but the processing efficiency is low and resources are wasted
Solution Approach 1:
Multiple light guide plates are merged into a single stack structure for simultaneous processing. The plates are laminated together with incident sides facing opposite directions, allowing the cutting and polishing equipment to process multiple plates in one operation, thereby improving productivity without significantly increasing device complexity
Solution Approach 2:
The processing system is segmented into modular components including the stack structure, support mechanisms, and processing heads. This segmentation allows the system to handle multiple plates while maintaining the simplicity of individual plate processing, resolving the contradiction between efficiency and complexity
2Productivity
If multiple light guide plates are stacked for batch processing, then processing efficiency improves, but maintaining neatness and flatness becomes difficult
Solution Approach 1:
Light guide plates with asymmetric thickness distribution (thicker incident side, thinner body) are arranged in reverse pairs. This asymmetric design allows the thicker incident sides to face opposite directions, creating a flat exterior surface when stacked, while the thinner bodies are positioned internally. This arrangement maintains manufacturing precision while enabling batch processing
Solution Approach 2:
Adjacent light guide plates in the stack are arranged in reverse orientation, with incident sides facing opposite directions. This inversion strategy ensures that the thicker portions of the plates are positioned on the exterior of the stack, maintaining flatness and neatness, while the thinner portions are positioned internally where they do not affect the overall geometry
3Adaptability or versatility
If light guide plates with varying incident side thicknesses are processed, then design flexibility improves, but processing uniformity becomes challenging
Solution Approach 1:
The light guide plates are designed with local quality variations, where the incident side has greater thickness than the body. This local thickness variation allows different regions of the plate to serve different functions while maintaining uniform processing characteristics when stacked in reverse pairs
Solution Approach 2:
The asymmetric thickness distribution (thicker incident side, thinner body) combined with reverse pairing creates a symmetric stack configuration. This approach allows design flexibility in individual plate geometry while achieving processing uniformity in the stacked configuration, as each plate's asymmetric features are compensated by its reverse-oriented neighbor

AI summary
A stack of light guide plates is proposed. Each light guide plate includes a light guide plate body and an incident side, thickness of the incident side is more than thickness of the light guide plate body, two light guide plates are reversely arranged and laminated when the two light guide plates are processed, and then a plurality of a pair of laminated light guide plates are stacked. The present embodiment provides a method for processing light guide plates. Even though the thickness of the incident side or the wedged shape of the incident side changes, the method can be adopted. The stack of light guide plates remain neat and flat using the method. Because a batch of light guide plates are cut and polished using the method, the efficiency in processing light guide plates improves. In this way, utilization of the equipment improves as well.
