Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle pane arrangements face challenges in providing reliable thermal and acoustic insulation while minimizing installation space and accommodating thermal expansion, with uniform spacings and orientations leading to inefficiencies in thermal insulation and structural stability.
Innovation Solution
A pane arrangement featuring asymmetrical spacings and curvatures between pane elements, with larger spacings in central regions to prevent collision and enhance thermal insulation, and smaller spacings at edges to save installation space, along with adaptive curvatures to accommodate environmental changes, allowing for targeted force absorption and improved structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform spacing is used between pane elements, then manufacturing and installation are simplified, but thermal insulation performance deteriorates due to insufficient spacing in central regions
Solution Approach 1:
The patent applies local quality by varying the spacing between pane elements based on their position: larger spacing (e.g., 5-10mm) in central regions for thermal insulation, and smaller spacing (e.g., 1-3mm) in edge regions for structural stability. This localized differentiation optimizes both thermal performance and structural integrity.
Solution Approach 2:
The patent implements asymmetry by intentionally creating non-uniform spacing patterns between pane elements, where central regions have greater spacing than edge regions. This asymmetric configuration breaks the uniformity to achieve superior thermal insulation in the most critical areas while maintaining overall structural stability.
2Loss of energy
If larger spacing is provided between pane elements, then thermal insulation is improved, but installation space requirement increases
Solution Approach 1:
The patent applies local quality by concentrating larger spacing (5-10mm) only in central regions where thermal insulation is most critical, while using smaller spacing (1-3mm) in edge regions. This localized approach optimizes thermal performance in the most important areas while minimizing the overall volume and installation space requirements.
Solution Approach 2:
The patent applies partial action by providing excessive spacing (5-10mm) only in specific central regions where thermal insulation is most needed, rather than uniformly across the entire pane assembly. This selective approach achieves sufficient thermal insulation performance while avoiding the penalty of increased overall installation space.
3Volume of moving object
If smaller spacing is used between pane elements, then installation space is reduced, but structural stability deteriorates due to collision risk during thermal expansion
Solution Approach 1:
The patent applies local quality by providing smaller spacing (1-3mm) specifically in edge regions where structural stability and collision prevention are critical during thermal expansion, while allowing larger spacing in central regions. This localized differentiation ensures structural integrity at the boundaries while optimizing thermal performance in the center.
Solution Approach 2:
The patent applies preliminary anti-action by pre-configuring appropriate spacing in edge regions to prevent collision between pane elements during thermal expansion. The smaller spacing (1-3mm) in edge regions is specifically designed to accommodate thermal movement while preventing contact, thereby proactively addressing the stability issue before it occurs.
4Loss of energy
If additional pane element is added for thermal insulation, then thermal and acoustic decoupling is improved, but installation space requirement increases
Solution Approach 1:
The patent applies local quality by implementing the second pane element with position-dependent spacing: larger spacing (5-10mm) in central regions for optimal thermal decoupling, and smaller spacing (1-3mm) in edge regions for structural stability. This localized approach maximizes thermal insulation performance while minimizing the overall installation space required for the multi-pane configuration.

Function Achieved in This Case
The pane arrangement achieves enhanced thermal insulation, reduced installation space usage, and improved structural stability by optimizing spacings and curvatures, while accommodating thermal expansion and environmental influences, resulting in improved passenger comfort and vehicle performance.
Implementation Method 1
The spacing between the pane elements changes after the initial operation of the vehicle due to the different temperatures in summer and winter
Implementation Method 2
A cavity which permits a low thermal conduction and thus improved thermal insulation is also formed by the third spacing between the first and second pane element

AI summary
A pane arrangement for a vehicle which has a first pane element which extends in a first vehicle direction and has a first edge and an opposing second edge in the first vehicle direction. The pane arrangement also has a second pane element which extends in the first vehicle direction, wherein the first pane element and the second pane element surround a pane intermediate space and have a first spacing from one another in a first region of the first edge, have a second spacing from one another in a second region of the second edge and have a third spacing from one another in a first central region which is arranged between the first region and the second region in the first vehicle direction. The third spacing is larger than the first spacing and/or than the second spacing.
