Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching paneling parts to radiators are either complex, visible, or not securely fixed, leading to detachment issues due to mechanical loads and tolerances, affecting the aesthetic and functional reliability of panel radiators.
Innovation Solution
A holding device with resilient legs and a cantilever-supporting guide shoe, featuring a coupling section that connects form-fittingly or force-fittingly to the radiator's inner sides, and a toothing mechanism to secure the cladding parts, ensuring easy assembly and permanent attachment without external fasteners being visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional parts and complex constructions are used to fix side panels securely, then the reliability of attachment is improved, but the device complexity increases and the ease of operation deteriorates
Solution Approach 1:
The holding device is divided into distinct functional segments: a coupling section for connecting to the paneling part, and a fastening section with resilient legs for securing to the radiator. This segmentation allows each part to perform its specific function optimally while keeping the overall structure simple and avoiding complex additional components.
Solution Approach 2:
The fastening section incorporates resilient (springy) legs that can dynamically adapt to tolerance variations in the radiator structure. These legs flex during assembly and maintain constant securing force, providing reliable attachment without requiring complex adjustment mechanisms or additional parts.
2Reliability
If resilient retaining clips are used to secure side parts, then the reliability of attachment is improved, but the ease of operation deteriorates due to difficult assembly and release
Solution Approach 1:
The resilient legs provide dynamic attachment that is both secure and easy to operate. During assembly, the legs flex outward to accommodate the paneling part, then spring back to secure it firmly. For release, the legs can be easily compressed to disengage, providing both reliable attachment and operational ease without complex mechanisms.
Solution Approach 2:
The resilient legs automatically adjust and secure the paneling part without requiring additional fastening actions. The elastic properties of the legs provide self-centering and self-securing functionality, eliminating the need for complex assembly procedures or multiple fastening steps.
3Manufacturing precision
If the fit between panel radiators and paneling parts is made precise, then the manufacturing precision is improved, but the cost increases due to tolerance compensation requirements
Solution Approach 1:
Instead of requiring precise dimensional parameters, the invention uses the elastic parameter of the resilient legs to compensate for tolerance variations. The legs can flex within a range that accommodates normal manufacturing tolerances, eliminating the need for expensive precision manufacturing while maintaining a secure fit.
Solution Approach 2:
The dynamic flexibility of the resilient legs allows the attachment to adapt to varying dimensions of the radiator and paneling part. This dynamic compensation mechanism replaces the need for precise static fits, reducing manufacturing costs while ensuring reliable attachment across production batches.
4Reliability
If conventional fasteners are used to attach paneling parts, then the reliability of attachment is improved, but the aesthetic appearance deteriorates due to visible fasteners
Solution Approach 1:
The holding device is nested within the structure formed by the paneling part and radiator, with the resilient legs positioned inside the channel system. This nesting conceals the fastening mechanism from external view while maintaining secure attachment functionality, achieving both reliability and aesthetic appearance.
Solution Approach 2:
The visible fastening elements are extracted from the external surface and relocated to the internal channel structure of the radiator. The resilient legs engage with the channel system from within, eliminating visible fasteners while maintaining secure attachment, thus preserving the aesthetic appearance.
