Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sunroof devices have complex and cumbersome assembly and disassembly processes due to snap-in connections, leading to increased device size and complexity.
Innovation Solution
A sunshade guide assembly with a support member and slider connected via a protrusion and positioning opening, allowing for a secure, yet easily removable fit, with the protrusion embedded into the positioning opening to restrict movement in the opening and closing direction, facilitating easier assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If snap-in connection is used to fix the support member and slider, then the connection is secure, but the assembly and disassembly process becomes complicated and the device size increases
Solution Approach 1:
The connection structure is segmented into a positioning opening on the support member and a corresponding protrusion on the slider. This segmentation allows the two components to connect through a simple insert motion rather than requiring complex snap-in mechanisms, thereby simplifying assembly and disassembly while maintaining connection security.
Solution Approach 2:
Instead of using a conventional snap-in connection where the slider would have to be clamped onto the support member, the design inverts the approach by having the protrusion on the slider insert into the positioning opening on the support member. This inversion transforms a complex clamping operation into a simple insertion motion, reducing assembly complexity while ensuring reliable connection.
2Reliability
If snap-in connection is used to fix the support member and slider, then the connection is secure, but the device size increases
Solution Approach 1:
The design extracts the essential function of connection security from the complex snap-in mechanism and implements it through a minimalistic protrusion-positioning opening structure. By removing unnecessary components and simplifying the connection geometry, the device volume is reduced while maintaining the secure connection between support member and slider.
Solution Approach 2:
The inverted connection approach allows for a more compact design compared to traditional snap-in mechanisms. The protrusion fits directly into the positioning opening without requiring additional clamping elements or complex joint structures, thereby reducing the overall device size while ensuring reliable connection.
3Stability of the object's composition
If the protrusion is embedded into the positioning opening to restrict relative movement in the opening and closing direction, then the connection stability is improved, but the assembly and disassembly convenience may be affected
Solution Approach 1:
The positioning opening and protrusion are designed with specific local geometric qualities that enable both stable connection and easy assembly. The opening has dimensions and shape characteristics that provide adequate restriction in the opening and closing direction while allowing straightforward insertion and removal motions, thus achieving both connection stability and assembly convenience through localized geometric optimization.

AI summary
A sunshade guide assembly and a sunroof device that reduces the size and being easy and convenient to assemble and disassemble are provided. The sunshade guide assembly guides a sunshade to move in an opening and closing direction, and includes a support member fixed to the sunshade and a slider fitted and connected to the support member. A protrusion is provided at a position of the slider corresponding to a positioning opening, and the protrusion is formed into a shape corresponding to the positioning opening. The protrusion is embedded into the positioning opening, so that the support member is fitted and connected to the slider, and the protrusion and the positioning opening are configured such that, in a state in which the protrusion is embedded into the positioning opening, the relative movement of the support member relative to the slider in the opening and closing direction is restricted.
