Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring the width of slots in folded cardboard boxes are imprecise, labor-intensive, and prone to operator error due to the use of non-specific tools like measuring tapes and calipers, leading to inconsistent and potentially erroneous measurements.
Innovation Solution
A compact, ergonomic measuring device with adjustable tabs and a biasing arrangement, such as a spring, that ensures consistent force application on the slot edges, allowing for accurate and reproducible width measurements without damaging the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical installations are used to measure slot width, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex optical measurement systems with a simple mechanical measuring device comprising a probe with contact elements that directly touch the slot edges. The mechanical system uses a spring-loaded mechanism to apply consistent force and a ruler or digital sensor to read the width, eliminating the need for expensive optical components while achieving sufficient measurement precision for quality control purposes.
2Device complexity
If manual measurement tools like measuring tapes are used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The measuring device is segmented into distinct functional components: a probe with contact elements that engage the slot edges, a spring mechanism that applies controlled force, and a reading mechanism (ruler or digital sensor). This segmentation allows each component to perform its specific function optimally, achieving precision comparable to optical devices while maintaining simplicity.
Solution Approach 2:
The patent changes the measurement parameters by using a mechanical contact system with controlled force application rather than visual estimation or flexible tape measurements. The spring-loaded contact elements ensure consistent pressure against the slot edges, eliminating the variability inherent in manual measurement techniques and achieving repeatable precision.
3Measurement precision
If standard calipers are used for measurement, then measurement precision may be improved, but ease of operation deteriorates due to operator skill dependence
Solution Approach 1:
The measuring device is designed to be self-regulating through its spring-loaded mechanism. The spring automatically applies the correct amount of force to contact the slot edges without requiring the operator to judge or control the pressure. The device self-adjusts to the slot width and provides a direct reading, eliminating the need for operator skill in force application and interpretation that plagues standard caliper usage.

AI summary
A measuring device for measuring a width (W) between a first edge (4) and a second edge (5) of spaced apart opposed edges (4, 5) of a slot (16) in a product (1'), comprising: - a measuring part (18), with a measuring detector and a display (28), and provided with a first tab (37) configured to enter into the slot (16), and - a slide (29), defining a longitudinal axis (X), being arranged so as to be adjustable relative to the measuring part (18) along the longitudinal axis (X), and provided with a second tab (46) being configured to enter into the slot (16). The slide (29) is adjusted so that a first surface (44) of the first tab (37) contacts the first edge (4) and a second surface (49) of the second tab (46) contacts the second edge (5). A distance (d) between the first surface (44) and the second surface (49) corresponding to the width (W) is detected by the measuring detector, and the value of the width (W) is displayed by the display (28). The first and second tabs (37, 46) are oriented downwardly relative to the measuring part (18), perpendicular or transverse to the longitudinal axis (X) of the slide (29).
