Solution Overview
Problem
Existing home appliance refrigeration devices face issues with seal compression leading to leakages and loss of sealing function due to excessive compression during the foaming process of the inner liner, affecting energy efficiency and durability.
Innovation Solution
The design incorporates an inner liner with protrusions that the seal abuts on, ensuring evenly distributed pressure and a defined range of compression, along with a thermal insulation inlay element protected by a foil to prevent moisture damage and improve handling, assembly, and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the thermal insulation inlay element is exposed during assembly, then the assembly process is simpler, but the thermal insulation inlay element is damaged by water and moisture during production and assembly
Solution Approach 1:
The protective foil is pre-applied to the thermal insulation inlay element before assembly operations. This preliminary protective action prevents water and moisture damage during the foaming and assembly processes, ensuring the thermal insulation maintains its durability throughout manufacturing.
Solution Approach 2:
The protective foil acts as an intermediary barrier between the thermal insulation inlay element and the harmful environment (water and moisture). This intermediate layer allows the thermal insulation to be handled and assembled without direct exposure to damaging elements.
2Productivity
If the seal is compressed without defined pressure distribution, then the assembly process is faster, but the seal compression is uneven causing leakages
Solution Approach 1:
The protrusions create localized high-compression zones at critical sealing interfaces while maintaining lower compression in non-critical areas. This non-uniform but controlled pressure distribution ensures reliable sealing at joints without requiring uniformly high compression across the entire seal, maintaining both speed and reliability.
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 solution enhances the energy efficiency, durability, and reliability of the seal, reducing the risk of damage and leakage while maintaining a safe and effective sealing function, and improves the overall assembly and thermal insulation of the appliance.
Implementation Method 1
The inner liner has at least one protrusion, which the seal abuts on in the assembled state
Implementation Method 2
the at least one thermal insulation inlay element is enclosed by the protective foil
