Delta Glass Fixing Structure Without C-Pillar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to fix and support a delta glass on a vehicle door frame from which a C-pillar is omitted, as existing methods rely on the C-pillar to install the delta glass, making it difficult to apply the delta glass type to door frames with steeply bent structures that cannot accommodate the C-pillar.
Innovation Solution
A structure comprising a delta outer reinforcing panel fixed on the door inner panel, a delta inner reinforcing panel, a rear channel, and a delta garnish that allows the rear end of the delta glass to be inserted and supported, enabling the delta glass to be fixed between the rear channel and a division channel on the door frame, even without a C-pillar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a C-pillar is used to fix the delta glass on the door frame, then the delta glass can be properly supported and fixed, but the door frame structure becomes more complex and cannot accommodate steeply bent designs
Solution Approach 1:
The invention extracts the C-pillar from the door frame structure, eliminating the need for this complex component while maintaining delta glass fixation functionality through alternative means (delta garnish and reinforcing panels directly integrated into the door frame)
Solution Approach 2:
The door frame is designed to perform multiple functions directly: it provides both the structural support and the fixation mechanism for the delta glass through integrated reinforcing panels and mounting structures, eliminating the need for separate C-pillar components
2Reliability
If a C-pillar is installed on the door frame to support the delta glass, then proper support is achieved, but the manufacturing process becomes more difficult due to steeply bent structures
Solution Approach 1:
The C-pillar component is removed from the manufacturing process entirely. The door frame is designed without this separate element, simplifying mold design and manufacturing operations while achieving the same support function through integrated structures
Solution Approach 2:
Instead of adding a C-pillar to provide support, the invention inverts the approach by designing the door frame itself to provide direct support through reinforcing panels and integrated mounting structures, eliminating the need for additional components
3Adaptability or versatility
If the door frame is designed with a steeply bent structure to achieve certain aesthetic or functional goals, then design flexibility is improved, but the C-pillar cannot be applied and delta glass installation becomes difficult
Solution Approach 1:
The door frame design integrates multiple functions: it maintains aesthetic steeply bent structures while simultaneously providing built-in reinforcing panels and mounting structures that enable delta glass installation without requiring a traditional C-pillar
Solution Approach 2:
Delta garnish and reinforcing panels serve as intermediary elements that bridge the gap between the steeply bent door frame structure and the delta glass, providing proper support and fixation while accommodating the unique door frame geometry

AI summary
A structure for fixing a delta glass for a vehicle is provided to fix and support a rear end portion of the glass on a door frame from which a C-pillar is omitted. The structure includes a delta outer reinforcing panel that is fixed on an upper portion of a door inner panel at a rear end portion of a door frame. A delta inner reinforcing panel is fixed to be positioned inside the delta outer reinforcing panel. A rear channel is installed between the delta outer reinforcing panel and the delta inner reinforcing panel to allow a rear end portion of the delta glass to be inserted into and supported by the rear channel. Additionally, a delta garnish is installed to cover the outside of the delta outer reinforcing panel and the delta glass is fixed between the rear channel and a division channel installed on the door frame.
