Solution Overview
Problem
Existing label dispensing devices lack precision in cutting adhesive strips, leading to accidental cuts and requiring multiple trips for operators to position multiple labels, which is detrimental to ergonomics and efficiency.
Innovation Solution
A device with unwinding and cutting means that uses an optical sensor and control system to detect predefined marks on the strip, allowing precise cutting independent of initial strip positioning and enabling programmable delivery of multiple labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cutting location is defined by the length of the unrolled paper strip, then the dispenser can operate with simple mechanics, but the cutting precision deteriorates and labels may be accidentally cut
Solution Approach 1:
The patent replaces the purely mechanical length-based cutting system with an optical detection system. An optical sensor detects predefined marks on the strip to determine cutting location, substituting mechanical measurement with optical sensing to achieve higher precision without significantly increasing overall system complexity
Solution Approach 2:
The patent introduces predefined marks on the strip as an intermediary element between the mechanical unwinding system and the cutting mechanism. These marks serve as reference points that the optical sensor detects to precisely determine where cutting should occur, eliminating the need for complex mechanical measurement systems
2Device complexity
If the dispenser delivers one label at a time with low accuracy, then the cutting mechanism remains simple, but the operator must make multiple trips between workstation and dispenser, deteriorating ergonomics
Solution Approach 1:
The patent implements a feedback mechanism where the optical sensor continuously monitors the position of labels and predefined marks on the strip. This feedback allows the system to accurately determine cutting locations and deliver multiple labels in sequence, enabling the operator to obtain all needed labels in one trip to the dispenser
Solution Approach 2:
The system performs preliminary detection of label positions and cutting locations using the optical sensor before actual cutting occurs. This allows the dispenser to prepare and deliver multiple labels in advance, reducing the number of trips the operator must make and improving ergonomics
3Ease of manufacture
If the initial positioning of the paper strip is not precise, then the loading process remains simple, but the cutting accuracy deteriorates because it depends on initial positioning
Solution Approach 1:
The patent incorporates predefined marks on the strip during manufacturing as a preliminary action. These marks serve as permanent reference points that remain valid regardless of how the strip is initially loaded, allowing the optical sensor to accurately determine cutting locations even when initial positioning varies
Solution Approach 2:
The system changes the reference parameter from absolute position (which depends on initial loading) to relative position based on detected marks. The optical sensor measures the position of predefined marks rather than assuming a fixed starting point, making cutting accuracy independent of initial strip positioning
