Light Display Toy Reset Mechanism Using Segmented Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light display toys require complex and costly mechanisms for initializing the display, involving structures that can trap fingers and are difficult to reset, necessitating high assembly efforts and costs.
Innovation Solution
A light display toy design featuring a transparent reset plate with projections that push translucent bodies back to their initial position, using a simple mechanism that moves parallel to a light shielding plate, combined with a light diffusion unit for even illumination and cylindrical projections for focused light display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a roller with projections is used to push back translucent bodies, then the reset function is achieved, but the device complexity and assembly cost increase
Solution Approach 1:
The roller is divided into multiple independent projections that can be separately manufactured and assembled. Each projection corresponds to a specific notch position, allowing modular assembly and simplifying the overall structure while maintaining the reset function.
Solution Approach 2:
The projections on the roller act as intermediary elements between the operator's action (rotating the roller) and the translucent bodies. By introducing these intermediate projection elements, the complex motion of manually pushing each translucent body is simplified into a single rotational action.
2Ease of operation
If fingers or tools are used to push translucent bodies, then initialization is achieved, but safety hazards arise from fingers getting caught
Solution Approach 1:
The roller with projections is designed to automatically push back the translucent bodies without requiring direct manual contact. The projections self-engage with the translucent bodies and perform the reset function through rotational motion, eliminating the need for fingers or tools to directly contact the moving parts.
Solution Approach 2:
The projections are designed as simple, replaceable elements on the roller. If a projection becomes worn or damaged, it can be easily replaced without replacing the entire mechanism, providing a cost-effective and safe solution compared to using fingers or expensive tools.
3Reliability
If the display body is removed and slid on the roller for initialization, then the reset function is achieved, but the operation becomes troublesome
Solution Approach 1:
The roller is designed to rotate dynamically within the display body housing, allowing the reset operation to be performed without removing the display body. The rotational motion of the roller dynamically engages with the translucent bodies and pushes them back to their initial positions while the display body remains in place.
Solution Approach 2:
The roller serves multiple functions: it acts as both the reset mechanism and a structural component of the display body assembly. By integrating the roller into the overall structure, the invention eliminates the need for separate initialization operations and makes the reset function an inherent part of the device's normal operation.

AI summary
A light display toy that can be initialized inexpensively and easily is provided. The light display toy comprises light sources, a front surface plate on which holes are arranged in parallel at prescribed intervals on one surface, a light shielding plate that is provided on the back surface side of the front surface plate, in which notches that can open and close are formed corresponding to the holes, that prevents light from the light sources on the back surface side from leaking out to the front surface side in a state with the notches closed, and allows light from the light sources to leak out to the front surface side in a state with the notches open, translucent bodies in which a portion can be pushed into the notches from the front surface side, with the notches opened by pushing in, and the translucent bodies illuminated by the light leaked from the notches to a front surface side, and a reset plate, configured to be able to move toward and away from the light shielding plate on the back surface side of the light shielding plate, on which projections corresponding to the notches are formed on the front surface, and by moving closer to the light shielding plate, uses the projections to push back the translucent bodies pushed into the notches, achieving a state with the notches closed.
