Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing skate-bear-shaped projection lamps have limited picture combinations, requiring complex operations to switch images, which can lead to user frustration and decreased interest, especially for children.
Innovation Solution
The design incorporates a skate-bear-shaped projection lamp with a projection head portion, a lower body, and a center column, featuring adjustable inner and outer annular picture plates, dynamic aurora light sources, and a rotary adjustment assembly, allowing for multiple angle adjustments and combination projections without the need for card insertion or frequent head portion removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If card insertion method is used for picture projection, then picture switching can be achieved, but the operation process becomes complex and requires frequent disassembly of the head portion
Solution Approach 1:
The patent applies the dynamics principle by making the picture plate rotatable rather than requiring disassembly. The picture plate can be rotated to different angles (0°, 45°, 90°, 135°, 180°, 225°, 270°, 315°) to switch between different projection images, transforming a static card insertion mechanism into a dynamic rotating mechanism that maintains head portion assembly while enabling picture switching.
Solution Approach 2:
The picture plate is divided into multiple independent picture regions arranged radially around the rotation center. Each picture region can be independently projected by rotating the picture plate to different angles, allowing multiple pictures to coexist on a single plate without requiring multiple separate cards or frequent disassembly.
2Adaptability or versatility
If multiple pictures are projected by arranging and combining several objects and backgrounds, then the number of picture combinations is limited, but the structure becomes more complex
Solution Approach 1:
The picture plate serves multiple functions: it acts as both the projection surface and the switching mechanism. By rotating the single picture plate to different angles, multiple different picture combinations can be achieved without adding separate switching components or mechanisms, thus achieving high adaptability with relatively simple structure.
Solution Approach 2:
The picture plate is designed with picture regions nested in a radial arrangement around the rotation center. Different picture regions are positioned at different angular positions, allowing multiple pictures to be contained within a single plate structure. This nested radial layout enables unlimited picture combinations through rotation without requiring multiple separate plates or complex assembly mechanisms.
3Adaptability or versatility
If the head portion is frequently removed and opened for picture replacement, then picture switching can be achieved, but moving components become insensitive or damaged
Solution Approach 1:
The patent transforms the picture replacement mechanism from a static disassembly-based system to a dynamic rotation-based system. The picture plate rotates in place within the head portion without requiring removal or disassembly, eliminating repeated mounting and removal operations that cause component damage and insensitivity.
Solution Approach 2:
The picture plate is designed to perform its own switching function through rotation without requiring external intervention or disassembly of the head portion. The rotating mechanism allows the picture plate to serve itself in switching between different projection images, eliminating the need for user intervention that would involve removing and opening the head portion.
