Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock-detecting apparatuses for industrial vehicles require time-consuming and unreliable trial-and-error methods to set appropriate threshold values, leading to decreased reliability and increased risk of cargo damage or vehicle breakdown due to excessive shocks.
Innovation Solution
A shock-detecting apparatus with a user-friendly interface that includes a liquid crystal display and input panel for monitoring shock values, allowing users to easily set and adjust threshold values automatically based on peak and maximum shock values detected by one-axis accelerometers, reducing the need for manual trial-and-error adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the threshold value is set by trial and error method, then the user can adjust the threshold value, but the reliability of the threshold value setting decreases and it takes time to improve reliability
Solution Approach 1:
The system performs preliminary actions by automatically collecting shock data during normal vehicle operation and pre-calculating the threshold value before the user needs to set it. The control unit accumulates shock values over a predetermined period and automatically determines the threshold, eliminating the need for time-consuming trial and error adjustments by the user.
Solution Approach 2:
The system serves itself by automatically setting the threshold value without requiring manual intervention. The control unit autonomously collects shock data, processes the information, and determines the appropriate threshold value based on actual operating conditions, making the system self-configuring and eliminating reliance on user trial and error methods.
2Productivity
If the threshold value is set arbitrarily, then the user can quickly initialize the system, but wrong warning signals are output and reliability decreases
Solution Approach 1:
The system incorporates feedback by continuously monitoring actual shock values during operation and using this information to automatically adjust and determine the threshold value. The control unit collects shock data from the sensor, processes it through the shock value computer, and uses the feedback from real operating conditions to set an accurate threshold that prevents wrong warning signals while maintaining quick system deployment.
3Reliability
If the shock value is monitored continuously, then cargo damage can be prevented, but the system complexity increases
Solution Approach 1:
The system merges multiple functions into a single control unit that performs shock detection, shock value computation, threshold determination, and warning signal generation. By integrating the shock-detecting sensor, shock value computer, and control unit with automatic threshold setting capability into one cohesive system, the patent reduces overall system complexity while maintaining continuous shock monitoring for cargo protection.

AI summary
A shock-detecting apparatus (1) for an industrial vehicle has a shock-detecting means (21,22) that is fixed to the industrial vehicle for detecting a shock and generating an output signal, a shock value computing means (S105) for computing a shock value based on the output signal which is received sequentially, a judging means (S106) for judging whether or not the shock value is greater than a threshold value, a warning means (S120) for generating a warning signal when the judging means judges that the shock value is greater than the threshold value and a threshold value setting means (7,30) for setting the threshold value. The threshold value setting means includes a displaying means (31) for displaying a peak value in a predetermined period which allows a user to read the peak value, wherein the peak value is determined by the computed shock value during the predetermined period and a threshold value input means (41) for inputting the threshold value manually.
