Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive-backed labels on terminal blocks often fail to adhere properly due to irregular surfaces, leading to unintended removal and loss of identification, and require specialized printing systems and software.
Innovation Solution
A terminal marker with flexible legs that can compress for printing in standard roll-fed thermal transfer printers, featuring hooks that extend and angle to secure the marker to the block, ensuring consistent adhesion and easy installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive-backed labels are used on terminal blocks, then identification can be provided, but the labels fail to adhere properly due to irregular surfaces and are vulnerable to unintended removal
Solution Approach 1:
The patent replaces the adhesive-based mechanical attachment system with a mechanical interlocking system. The molded terminal markers incorporate latches that physically engage with the terminal block structure, eliminating dependence on adhesive bonds that fail on irregular surfaces. This mechanical substitution provides reliable attachment without being affected by surface irregularities.
Solution Approach 2:
The patent changes the attachment mechanism from chemical adhesion to mechanical engagement. By molding the terminal markers with integrated latches that physically interlock with the terminal block, the system transitions from a chemistry-based attachment (adhesive) to a mechanics-based attachment, fundamentally changing how the marker attaches to the block.
2Ease of manufacture
If specialized printing systems are used for terminal markers, then identification can be printed, but the system complexity and cost increase
Solution Approach 1:
The patent makes the terminal marker compatible with universal standard label printers rather than requiring specialized printing equipment. The marker design accommodates standard thermal transfer or inkjet printers, allowing the same printing infrastructure used for general labeling to be used for terminal markers, thereby eliminating the need for dedicated specialized printing systems.
Solution Approach 2:
The patent uses standard labeling technologies (thermal transfer or inkjet printing) that are already widely deployed for general purposes. By copying the approach of standard label printing and adapting it to terminal markers through appropriate material selection and design, the system leverages existing, proven technology rather than developing or requiring specialized printing equipment.
3Strength
If rigid terminal markers are used, then mounting strength is provided, but the markers cannot be compressed for roll-fed printer feeding
Solution Approach 1:
The patent introduces dynamic flexibility to the terminal marker through the leg structure. The legs are designed to be flexible enough to allow compression and expansion during the printing process, enabling the marker to be fed through roll-fed printers. After printing, the legs return to their original position to provide mounting strength, thus dynamically adapting between two functional states.
Solution Approach 2:
The patent divides the terminal marker into a rigid body portion and flexible leg portions. This segmentation allows different parts of the marker to have different mechanical properties: the main body remains rigid for structural integrity and mounting strength, while the legs are made flexible to enable compression for printer feeding. This division of functionality resolves the contradiction between rigidity and compressibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The terminal marker provides reliable identification of terminal blocks with improved adhesion and compatibility with common printing systems, reducing production costs and ensuring easy installation and resistance to vibration.
Implementation Method 1
The legs are molded from a thermoplastic material that includes elastic properties to allow the legs to bend and flex to accommodate the printing operation. Once the terminal marker exits the printing operation, the legs return to the installed state without force or manipulation by a user.

AI summary
The present invention is directed toward a terminal marker (240) used to identify a terminal block (220). The terminal marker (240) includes a front having a print surface, a back, sides, and flexible legs. The flexible legs can be positioned in a natural state for installation in the terminal block (220) or a compressed state for obtaining a marking from a printer. In the natural state, the flexible legs extend at an angle with respect to the print surface of the terminal marker (240). In the compressed state, the flexible legs extend outward beyond of the sides of the terminal marker (240).
