Solution Overview
Problem
Acoustic partition systems in sports halls deteriorate significantly when closed, leading to increased reverberation time and flutter-echoes, which compromises sound control and fails to meet noise standards.
Innovation Solution
A modular partition system with motorized moving means, comprising partition screens and sound-insulating strips connected by longitudinal connecting elements, such as kador rails, allowing for easy assembly, maintenance, and customization of acoustic characteristics.

Engineering Contradiction Analysis
1Shape
If partition systems are closed to divide the sports hall into smaller sections, then spatial separation is achieved, but acoustic characteristics deteriorate significantly with increased reverberation time and flutter-echoes
Solution Approach 1:
The partition is divided into multiple modular components including partition screens, sound insulating strips, and connecting elements. The sound insulating strips are segmented and positioned at specific locations to create acoustic chambers, allowing the partition to provide both spatial separation and acoustic control independently
Solution Approach 2:
The partition combines different materials with complementary acoustic properties: partition screens for spatial division, sound absorbing materials within the screens, and sound insulating strips spanning between screens. This composite structure addresses both the spatial separation requirement and the harmful acoustic effects simultaneously
2Ease of repair
If modular partition components are used to allow separate replacement for maintenance or repair, then ease of maintenance is improved, but device complexity increases due to multiple separate components
Solution Approach 1:
The partition is designed as modular components (partition screens, sound insulating strips, connecting elements) that can be independently replaced. This segmentation enables easy maintenance while the standardized connection methods keep the overall system relatively simple
Solution Approach 2:
Multiple functional elements are combined into integrated assemblies. The connecting elements simultaneously join partition screens and support sound insulating strips, reducing the number of separate connection components needed while maintaining ease of replacement
3Strength
If traditional partition assembly methods are used, then structural integrity is achieved, but mounting time is significantly increased
Solution Approach 1:
The partition components are designed with pre-integrated connection features. The connecting elements have built-in attachment mechanisms that allow partition screens and sound insulating strips to be quickly connected without requiring separate fastening operations, reducing mounting time while maintaining structural integrity
Solution Approach 2:
Traditional mechanical fastening systems are replaced with simplified connection mechanisms. The connecting elements use integrated attachment features that enable quick assembly without complex mechanical fasteners, significantly reducing mounting time while preserving structural strength

AI summary
The invention relates to a partition (14) for use in halls, such as sports halls, comprising at least one pair of partition screens (12) comprising sound absorbing material, that are interconnected at a predetermined mutual distance by a series of strips (36) of sound insulating material essentially extending over the width of the partition screens. Each partition screen (12) comprises two or more partition screen parts (13) that are arranged for releasable connection to form the partition screen. A series of strips (36) comprising sound insulating material span the distance between the partition screens (12). The partition further comprises a number of separate connecting elements (20) that are each arranged for releasably connecting two partition screen parts (13) and a strip (36), wherein the connecting elements have a general longitudinal shape and, in the assembled state, essentially extend in lateral direction of the partition screen (12).
