Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior temperature measurement systems are prone to incorrect positioning due to component tolerances, leading to assembly issues with clipped or snapped structures.
Innovation Solution
A device featuring a plug-in housing with a locking mechanism and biasing means, ensuring precise positioning of an interior temperature sensor within a cover element, using elastic components like spring elements to maintain thermal coupling and prevent loose assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If clip or snap or locking structures are used to assemble component parts, then assembly is simplified and productivity is improved, but component tolerances lead to incorrect positioning and assembly stability deteriorates
Solution Approach 1:
The patent introduces a biasing means that changes the mechanical state of the plug-in housing by applying a predetermined force, thereby compensating for tolerance variations in the plug-in connection. This ensures accurate positioning of the interior temperature sensor regardless of manufacturing tolerances in the clip or snap structures.
Solution Approach 2:
The biasing means is pre-configured to apply a predetermined biasing force that anticipates and compensates for potential positioning errors due to tolerances. This preliminary action ensures that the plug-in housing is always pushed into the correct position, preventing incorrect assembly before it occurs.
2Stability of the object's composition
If a plug-in housing with locking means is used, then assembly stability is improved, but the complexity of the device increases due to additional components
Solution Approach 1:
The patent combines the biasing means with the plug-in housing as an integrated component, rather than adding it as a separate assembly step. This merging approach maintains assembly stability while minimizing the increase in device complexity by consolidating functions into existing structural elements.

AI summary
A device for measuring the temperature in the interior of a vehicle is provided. The device includes an interior temperature sensor arranged at and/or in a plug-in end of a plug-in housing. The interior temperature sensor projects beyond the plug-in end of the plug-in housing. The plug-in housing is biased away from a cover element for assuming a defined plug-in position of the plug-in housing when the plug-in end of the plug-in housing is plugged into a receiving space of the latter and the interior temperature sensor is arranged in the through-going opening of the cover element.
