Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit modifiers lack precise control over the deployment of their modification mechanisms, often deploying too quickly or too slowly when trigger conditions are met, making them unpredictable.
Innovation Solution
An apparatus and method utilizing a movable electrical coupler within a housing, driven by an expanding material at elevated temperatures and inhibited by a spring-based mechanism, allowing precise control over the movement and electrical coupling, ensuring the coupler contacts a second housing only after a predetermined distance is traversed, thereby modifying the electrical circuit with controlled precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional circuit modifiers are used, then the circuit modification function is achieved, but the deployment timing and speed are unpredictable and lack precise control
Solution Approach 1:
The patent changes the physical state of the expanding material through temperature parameter control. When the temperature reaches a predetermined threshold, the material undergoes expansion, which drives the electrical coupler to move along the movement axis. This temperature-triggered parameter change provides precise control over when the circuit modification deploys, resolving the unpredictability issue of conventional modifiers.
Solution Approach 2:
The patent replaces conventional mechanical switching mechanisms with a thermally-driven expanding material system. The expanding material converts thermal energy into mechanical displacement, pushing the electrical coupler to establish or break circuit connections. This substitution eliminates the need for complex mechanical actuators while achieving precise deployment timing through temperature control.
2Speed
If the electrical coupler moves quickly upon trigger, then the response time is fast, but the deployment becomes uncontrollable and may deploy too quickly
Solution Approach 1:
The patent introduces the expanding material as an intermediary between the temperature trigger and the electrical coupler. Instead of directly actuating the coupler when triggered, the system uses the expanding material to mediate the force transmission. This intermediary provides a controlled rate of expansion that regulates the coupler's movement speed, preventing overly rapid deployment while maintaining responsive action.
Solution Approach 2:
The expanding material undergoes a gradual expansion process rather than instantaneous movement. This creates a periodic or progressive action where the coupler moves along the movement axis in a controlled sequence, allowing precise timing control. The expansion occurs over a defined period, ensuring the coupler reaches its destination at the exact moment when the trigger condition is satisfied.
3Measurement precision
If the electrical coupler moves slowly to ensure precision, then the deployment timing is accurate, but the response becomes too slow
Solution Approach 1:
The system uses temperature as a critical parameter that, when reached, triggers rapid expansion of the material. This parameter change creates a swift response once the threshold is met, ensuring high productivity. The predetermined temperature threshold ensures that the expansion—and thus the coupler movement—occurs quickly and decisively, avoiding overly slow deployment while maintaining precision through the defined trigger point.
4Device complexity
If a simple thermal expansion mechanism is used, then the device structure is simple, but the control over movement rate and timing is insufficient
Solution Approach 1:
The patent segments the apparatus into distinct functional portions: a driving portion containing the expanding material, an inhibiting portion that applies restraining force, and the electrical coupler itself. This segmentation allows each component to be optimized for its specific function while maintaining overall structural simplicity. The inhibiting portion, in particular, provides controlled resistance that regulates the coupler's movement rate without adding complex control systems.
Solution Approach 2:
The inhibiting portion acts as a counterbalancing element that applies restraining force against the expanding material's driving force. This counterforce mechanism provides precise control over the electrical coupler's movement rate along the movement axis. By balancing the expansion force with controlled inhibition, the system achieves accurate timing and speed control while keeping the overall device structure relatively simple.

AI summary
An apparatus for modifying an electrical circuit includes a first electrical contact, a second electrical contact, an electrical coupler formed of an electrically conductive material, a first assembly including a cavity, a driving portion, an inhibiting portion, and a second assembly electrically coupled to the second electrical contact. The electrical coupler is moveable within the cavity along a movement axis, a wall of the cavity is electrically coupled to the first electrical contact and to the electrical coupler, and when the electrical coupler is disposed at an initial position within the cavity, the electrical coupler is not electrically coupled to the second electrical contact. The driving portion applies a first force on the electrical coupler in a movement direction along the movement axis. The inhibiting portion inhibits the movement of the electrical coupler along the movement axis.
