Solution Overview
Problem
Current laser lamps are limited to static image display, and achieving dynamic image transformation, translation, and rotation is challenging due to complex structures and high costs, with existing solutions failing to provide an ideal dynamic display effect without increasing system complexity or cost.
Innovation Solution
A circumferential laser dynamic display device featuring an inner frame with multiframe microstructures, a rotating shaft, and a sheet metal part with through holes, allowing the inner frame to move circumferentially relative to the laser, driven by a rotating shaft, which enables smooth transition between image frames without additional movement control units, maintaining low cost and system volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the whole ring-shaped diffractive optical element moves circumferentially to achieve dynamic image display, then the representation content and effect are improved, but the structure becomes complex and images rotate around a rotation center causing image swing
Solution Approach 1:
The patent divides the diffractive optical element into two independent parts: an inner frame containing multiple frame microstructures and an outer frame. The inner frame can move independently within the outer frame, allowing dynamic image display without requiring the entire ring-shaped element to move, thus reducing structural complexity while maintaining adaptability
Solution Approach 2:
The patent extracts the moving part (inner frame) from the whole ring-shaped diffractive optical element. By making the inner frame movable within the outer frame, the patent achieves dynamic image display without requiring the entire element to move, eliminating the image swing problem caused by rotation of the whole element
2Adaptability or versatility
If multiple frames of images are arranged in a sector to form a ring for dynamic display, then the representation effect is improved, but the cost and system complexity increase
Solution Approach 1:
The patent combines multiple frames of images into a single inner frame structure that contains all frame microstructures. This inner frame is then integrated into the outer frame, creating a compact unified device that achieves dynamic display without increasing system complexity
Solution Approach 2:
The patent implements a nested structure where the inner frame (containing multiple frame microstructures) is placed within the outer frame. This nesting allows multiple images to be contained in a compact space, enabling dynamic display while maintaining low system complexity and cost

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves dynamic image display with a simplified structure and low cost, enhancing the representation effect of laser lamps by synchronizing the optical design of the diffractive optical element with the mechanical movement, allowing for seamless translation and rotation of images without increasing system complexity or cost.
Implementation Method 1
The diffractive optical element can be used for outputting incident dot laser as a required image by utilizing a diffractive effect of the micro/nano-scale structures on light
Implementation Method 2
one end of the rotating shaft is fixedly connected with a driving shaft, the other end of the rotating shaft is rotatably connected with the inner frame, and the rotating shaft can drive the inner frame to do translational movement when rotating
