Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical installation devices are not cost-effective and lack flexibility in configuration and operation, particularly in managing simultaneous actuation of multiple pushbuttons.
Innovation Solution
An electrical installation device with a common actuating button that can activate multiple pushbuttons simultaneously, accompanied by an electronic means to output a single switching signal within a predetermined time window, and optionally mechanical means to ensure single actuation, along with a modular design and a display for flexible functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pushbuttons are actuated simultaneously within a time window, then multiple switching signals are generated, but this causes bounce-free switching to fail and creates operational errors
Solution Approach 1:
An electronic means is introduced as an intermediary between the pushbuttons and the switching signal output. This electronic means monitors multiple pushbuttons simultaneously and acts as a mediator to ensure that only a single switching signal is generated even when multiple buttons are actuated within a predetermined time window, thus preventing bounce-free switching failures
Solution Approach 2:
The electronic means performs preliminary detection and evaluation of pushbutton actuations before generating switching signals. By monitoring which button was actuated first within the time window and disabling subsequent buttons, the system proactively prevents multiple signal generation, ensuring reliable single-signal output before any potential errors can occur
2Reliability
If traditional individual button actuation is used, then each button requires separate handling, but this increases device complexity and reduces manufacturing efficiency
Solution Approach 1:
Multiple pushbuttons are merged under a single common actuating button structure. Instead of requiring separate actuating mechanisms for each button, the invention combines them so that one actuating button can activate multiple pushbuttons simultaneously, simplifying the overall device structure while maintaining reliable switching signal generation through the electronic means
3Ease of manufacture
If fixed button configuration is used, then manufacturing is simpler, but the device lacks flexibility for different applications
Solution Approach 1:
The button configuration is made dynamic and reconfigurable rather than fixed. The electronic means can be programmed to recognize different button arrangements and activate appropriate pushbuttons based on the specific application requirements. This allows the same physical device to be adapted to various configurations (1, 2, 4, or more buttons) without requiring different manufacturing processes
