Test Table for Crash Test Dummy Certification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional certification methods for crash test dummies are labor-intensive and time-consuming due to the physical demands of handling large and heavy dummies, requiring multiple precise repositionings for various tests, which limits the number of certifications that can be completed daily and results in inefficient use of resources.
Innovation Solution
A test table with a height-adjustable and horizontally adjustable lifting table, equipped with a hoist and a support structure that acts as a counterweight, allows for ergonomic and precise positioning of the dummy relative to a reference point, reducing the effort required for certification and enabling faster processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional certification methods are used with fixed test pendulum arrangements, then measurement precision is maintained, but productivity decreases due to time-consuming manual repositioning
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed, static test pendulum arrangement with a movable, adjustable pendulum that can be repositioned along the longitudinal axis of the test table. This dynamic configuration allows the test pendulum to be quickly moved between different test positions without requiring manual repositioning of the entire crash test dummy, thereby increasing productivity while maintaining measurement precision through controlled, repeatable positioning.
Solution Approach 2:
The patent implements universality by designing a test table that serves multiple functions: it provides both a stable platform for the crash test dummy and an integrated movable pendulum system. This multi-functional design eliminates the need for separate repositioning operations and allows a single device to perform multiple certification tests efficiently, thereby increasing the number of certifications that can be completed daily.
2Measurement precision
If crash test dummies are positioned precisely for each test, then measurement precision is improved, but ease of operation deteriorates due to physical demands on personnel
Solution Approach 1:
The patent applies mechanics substitution by replacing the manual mechanical effort required for positioning with an automated drive mechanism. The drive mechanism automatically positions the test pendulum along the longitudinal axis, eliminating the need for personnel to manually handle and reposition the heavy crash test dummy multiple times, thereby reducing physical effort while maintaining precise positioning through controlled mechanical movement.
3Reliability
If multiple tests are conducted on the same dummy, then reliability of certification is improved, but productivity decreases due to repeated repositioning requirements
Solution Approach 1:
The patent applies dynamics by enabling the test pendulum to move dynamically along the longitudinal axis of the test table while the crash test dummy remains stationary. This allows multiple different tests to be conducted on the same dummy without requiring physical repositioning of the dummy itself, thereby maintaining certification reliability through varied test configurations while increasing productivity through efficient, repeatable testing sequences.
