Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a backing part in refrigeration appliances is often complex and requires additional components, leading to potential gaps and instability due to production tolerances and the need for precise anchoring within the cavity filled with insulation material.
Innovation Solution
A spring arm mechanism integrated into the wall element allows for secure anchoring of the backing part without additional components, using existing wall elements and ensuring the backing part is pressed against the rear wall by spring force, preventing insulation material escape and stabilizing the component during foam curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the backing part is anchored using additional components (adhesive tape, snap-in connections), then the anchoring stability is improved, but the device complexity and installation complexity increase
Solution Approach 1:
The spring arm mechanism is integrated directly into the wall element, merging the anchoring function with the existing structural component. This eliminates the need for separate adhesive tapes or snap-in connections, reducing device complexity while maintaining anchoring stability through the spring arm's elastic engagement with the cavity.
Solution Approach 2:
The spring arm mechanism provides self-service anchoring by using its own elastic deformation to create securing force. The spring arm automatically engages with the cavity wall through its spring force, eliminating the need for additional anchoring components or complex installation procedures, thereby reducing both device complexity and installation complexity.
2Reliability
If the backing part is firmly anchored to prevent insulation material escape, then the reliability is improved, but the manufacturing precision requirements increase due to production tolerances
Solution Approach 1:
The spring arm mechanism changes the physical parameter of force application by using elastic deformation to create a dynamic securing force. This allows the backing part to be firmly anchored against insulation material escape while compensating for production tolerances, as the spring force can adapt to position variations without requiring high manufacturing precision.
Solution Approach 2:
The spring arm mechanism provides beforehand cushioning by using its elastic properties to absorb and compensate for positioning deviations. The spring force acts as a buffer that maintains reliable sealing despite production tolerances, preventing insulation material escape without requiring extremely precise manufacturing.
3Stability of the object's composition
If the backing part is pressed against the rear wall by spring force, then the stability during foam curing is improved, but the force applied increases which may deform the wall element
Solution Approach 1:
The spring arm mechanism introduces dynamics to the anchoring system, allowing the backing part to be held in position through elastic force rather than rigid constraint. The spring force provides continuous positional stability during foam curing while adapting to wall element deformation, maintaining balance between stability and stress application.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method simplifies and secures the installation of the backing part, eliminating gaps and ensuring precise anchoring, even with production-related deviations, and allows for easy, one-handed assembly without the need for additional components.
Implementation Method 1
the spring arm according to the invention now makes it possible that tolerances caused by production technology when making the opening do not have any influence on the secure anchoring of the backing part on the wall element. Rather, the backing part is securely pressed against the rear wall by means of the spring force generated by the spring arm
