Vehicle Windshield Bracket Structure for Fast, Firm Pillar Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing windowshield attachment methods for off-road vehicles, which rely solely on adhesives, are time-consuming and do not provide a secure attachment to the pillars, making it difficult to firmly attach the windowshield.
Innovation Solution
A bracket system is introduced that attaches to the windowshield and extends along the pillar's surface, featuring a tip end portion inclined downward, allowing for easy and secure fixation without the need for adhesive curing, using a hook-shaped holding portion that contacts the pillar's seal surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive-only attachment method is used, then the windowshield can be attached to the pillar, but it takes time for adhesive curing and the attachment is not firm enough
Solution Approach 1:
The attachment function is segmented into two independent methods: adhesive bonding and mechanical bracket fixation. The bracket is divided into separate components (bracket body, holding portion, fastening portion) that can be independently installed to provide immediate mechanical support while adhesive cures, eliminating the need to wait for adhesive curing and ensuring firm attachment.
Solution Approach 2:
The bracket acts as an intermediary mechanical element between the windowshield and pillar. It provides temporary mechanical support during the adhesive curing process and continues to provide structural support afterward, serving as a mediator that bridges the gap between initial attachment and final cured state.
2Reliability
If adhesive-only attachment method is used, then the attachment process is simple, but it is difficult to firmly attach the windowshield to the pillar
Solution Approach 1:
The attachment system is segmented into modular components: the bracket body attached to the windowshield, the holding portion that contacts the pillar, and the fastening portion that secures the bracket. This segmentation allows each component to perform its specific function while maintaining overall structural firmness without excessive complexity.
Solution Approach 2:
The patent replaces the purely chemical adhesive bonding system with a mechanical bracket-based system. The bracket uses mechanical fastening (screws, clips, or other fasteners) to attach the windowshield to the pillar, providing immediate and adjustable firm attachment without relying solely on chemical curing processes.
3Reliability
If the bracket extends along the pillar surface, then the windowshield can be firmly fixed, but the bracket structure becomes more complex
Solution Approach 1:
The holding portion of the bracket is designed with a curved surface that matches the curvature of the pillar surface. This curved geometry allows the bracket to conform to the pillar's shape, providing stable contact and fixation while maintaining a simple, elegant structure rather than requiring multiple flat surfaces or complex adjustment mechanisms.
Solution Approach 2:
The bracket structure applies local quality by having different geometric characteristics in different regions: the bracket body has a specific shape for attachment to the windowshield, while the holding portion has a curved surface matching the pillar. Each region is optimized for its specific function, achieving stable fixation without overall structural complexity.

AI summary
A windowshield attachment structure includes a windowshield defining the front or rear of a vehicle compartment of an off-road vehicle, a pillar arranged inward of the vehicle compartment with respect to the windowshield in a front-rear direction, a door defining a side of the vehicle compartment, and a bracket attached to the windowshield and fixing the windowshield to the pillar. The pillar has a seal surface facing outward of the vehicle compartment. The door has a seal contacting the seal surface in a closed state. The bracket extends from the windowshield to the seal surface along a surface of the pillar on the side opposite to the windowshield. A tip end portion of the bracket is arranged on the seal surface. An upper edge of the tip end portion is inclined with respect to the horizontal direction so as to be positioned downward toward the windowshield.
