Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor structures for leisure activities fail to balance legal requirements for fall protection with the need for an attractive, customizable visual appearance, particularly in environments like hotels and playgrounds.
Innovation Solution
A floor structure comprising an elastic damping underlay and a motif top layer connected over a large area using a polyurethane adhesive, with the underlay plates or webs providing impact sound insulation and fall protection, and a multilayer motif top layer for visual customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a floor structure uses a stable connection between top layer and underlay, then structural stability is improved, but manufacturing complexity increases due to adhesive application requirements
Solution Approach 1:
A adhesive layer is introduced as an intermediary substance between the motif top layer and damping underlay to achieve stable connection. The adhesive layer is applied to the upper side of the damping underlay, allowing the motif top layer to be connected over a large area while simplifying the manufacturing process compared to mechanical fastening methods.
2Stability of the object's composition
If the motif top layer is connected over a large area to the damping underlay, then structural stability is improved, but adhesive material consumption increases
Solution Approach 1:
The adhesive layer is applied to cover a large area of the damping underlay's upper side, extending beyond the minimal required connection area. This excessive action ensures stable connection of the motif top layer during leisure activities while maintaining practical adhesive consumption levels through optimized application coverage.
3Reliability
If the floor structure provides fall protection and impact sound insulation, then safety is improved, but the visual appearance and customization options are limited
Solution Approach 1:
The floor structure is segmented into two independent functional layers: a motif top layer for visual appearance and customization, and a damping underlay for fall protection and impact sound insulation. This segmentation allows each layer to be optimized for its specific function while maintaining overall structural integrity and safety.
Solution Approach 2:
The damping underlay serves multiple functions simultaneously: providing fall protection, impact sound insulation, and a stable base for the motif top layer. The motif top layer can be customized with different motifs, colors, and designs while maintaining the safety functions of the underlying damping structure.
