Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature-dependent switches face challenges in maintaining easy electrical connectivity and effective sealing due to offset external terminals, which complicates the connection process and increases the risk of damage or malfunction.
Innovation Solution
A temperature-dependent switch design featuring a housing with an insulating material carrier that keeps electrodes at a distance, allowing external terminals to be led out at the same height and in a common plane, facilitated by a connection element that internally connects the electrode to the external terminal, improving both electrical connectivity and sealing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external terminals are led out at offset heights to accommodate electrode positioning, then electrical connectivity is maintained, but connection complexity increases and sealing effectiveness deteriorates
Solution Approach 1:
The patent introduces a connection element that extends in the height dimension to bridge the offset between electrodes and external terminals. This allows terminals to be positioned at the same height externally while internally connecting to electrodes at different heights, thus resolving the contradiction between sealing effectiveness and electrical connectivity.
Solution Approach 2:
The connection element acts as an intermediary component between the electrodes and external terminals. It mediates the height offset issue by providing an internal connection path, allowing both electrodes and terminals to be positioned optimally without compromising sealing or connectivity.
2Ease of operation
If external terminals are bent to achieve common plane alignment, then ease of connection is improved, but risk of damage increases
Solution Approach 1:
The connection element is pre-formed with the appropriate geometry to connect electrodes to terminals in the common plane. This preliminary preparation eliminates the need for bending terminals during installation, thus improving ease of connection while preventing terminal damage.
Solution Approach 2:
The patent replaces the mechanical bending of terminals with a pre-formed connection element that provides the necessary geometric adaptation. This substitution eliminates the harmful mechanical stress of bending while achieving the same goal of common plane alignment.
3Reliability
If electrodes are positioned at different heights to maintain electrical connectivity, then electrical function is preserved, but sealing complexity increases
Solution Approach 1:
The connection element serves as an intermediary that bridges the height difference between electrodes and terminals. It allows electrodes to be positioned at different heights for electrical functionality while maintaining a simple sealing structure at the terminal level.
Solution Approach 2:
The connection element utilizes the internal height dimension to accommodate electrode positioning while presenting a unified common plane at the external terminal level. This resolves the contradiction by separating the internal electrical arrangement from the external sealing interface.
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 design simplifies the electrical connection process by eliminating the need to bend terminals and enhances sealing by allowing mechanical sealing at a single height, reducing the risk of damage and improving the switch's overall performance.
Implementation Method 1
a temperature-dependent switching element, which is configured to change its geometric shape depending on its temperature. This temperature-dependent switching element changes its geometric shape when the response temperature of the switch is reached and/or exceeded
Implementation Method 2
The temperature-dependent switching element therefore switches from its low-temperature configuration to its high-temperature configuration temperature-dependently in the manner of a hysteresis
Implementation Method 3
an additional spring element, which generates, or at least is involved in generating, the mechanical closing pressure of the switching mechanism in the closed position

AI summary
A temperature-dependent switch having a housing and a temperature-dependent switching mechanism arranged therein. The temperature-dependent switching mechanism switches, depending on its temperature, between a closed position, in which the switching mechanism establishes an electrically conductive connection between a first electrode and a second electrode, and an open position, in which the temperature-dependent switching mechanism disconnects the electrically conductive connection. The housing comprises an insulating material carrier, which carries the two electrodes and keeps them at a distance from each other along a height direction. The first electrode is electrically connected to a first external terminal. The second electrode is electrically connected to a second external terminal. The first electrode is electrically connected to the first external terminal by a connection element aligned transversely in relation to the two electrodes and arranged in the housing. The two external terminals are led through the insulating material carrier at the same height.
