Solution Overview
Problem
Existing thermal engineering devices face challenges in easy assembly and long-term secure positioning of functional components, often requiring additional fixing elements and risking slippage during operation.
Innovation Solution
The integration of first and second form-fitting elements on the receiving area and functional component, respectively, provides axial fixation in addition to radial fixation, eliminating the need for additional fixing elements and ensuring secure positioning without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only radial fixation is used for the functional component in the receiving area, then the device structure remains simple, but the functional component may slip during operation and requires additional fixation elements
Solution Approach 1:
The patent combines radial fixation and axial fixation into a unified form-locking system. The receiving area features both a radial form-locking element (groove) and an axial form-locking element (protrusion), which work together to secure the functional component without requiring separate fixation elements, thus improving reliability while maintaining structural simplicity
Solution Approach 2:
The patent transitions from single-dimensional radial fixation to two-dimensional fixation by adding axial fixation. The form-locking elements extend the securing mechanism from one dimension (radial) to two dimensions (radial + axial), preventing slippage in multiple directions without significantly increasing overall device complexity
2Reliability
If additional fixation elements are used to secure the functional component, then positioning stability improves, but assembly complexity and time increase
Solution Approach 1:
The form-locking elements are integrated directly into the insulating body's receiving area, allowing the structure to secure itself. The functional component's form-locking element automatically engages with the receiving area's form-locking features during assembly, eliminating the need for separate fixation elements and simplifying the assembly process
Solution Approach 2:
The patent merges the fixation function into the existing insulating body structure. The receiving area is designed with integrated form-locking elements that combine both radial and axial securing functions, eliminating the need for additional separate fixation elements and reducing assembly complexity
