Solution Overview

Problem

Conventional printing apparatuses face challenges in accurately positioning multiple tapes stuck together, leading to low workability due to adhesive portions adhering to hands or objects instead of the intended surface.

Innovation Solution

A tape configuration featuring a strip-shaped sheet with first and second media spaced apart in the longitudinal direction, each having a separating line that allows for easy peeling and sticking without exposing the entire sheet surface, enabling precise alignment and separation along designated lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the entire release paper is peeled off for positioning, then the tapes can be stuck together, but the adhesive portions may adhere to user's hand or object, leading to low workability

Engineering Contradiction:
Improveworkability in stickingVSAvoidadhesive adhering to hand or object
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The release paper is divided into multiple regions corresponding to different tape portions. Only the release paper portion underlying the non-sticking region needs to be peeled off, rather than the entire release paper. This segmentation allows selective exposure of adhesive portions, preventing adhesive from adhering to the user's hand or objects while still enabling positioning and sticking of the tapes together.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If the adhesive portion is exposed for positioning, then the tapes can be aligned, but the exposed adhesive may stick to unintended surfaces

Engineering Contradiction:
Improvepositioning accuracyVSAvoidadhesive sticking to unintended surfaces
Core Design Contradiction:
Measurement precisionVSObject-generated harmful factors

Solution Approach 1:

The tape structure incorporates a non-sticking region with different adhesive properties than the sticking regions. The release paper is peeled off only in the local area corresponding to the non-sticking region, exposing adhesive only where needed for positioning without exposing adhesive portions that would stick to unintended surfaces. This local quality differentiation enables precise positioning while preventing harmful adhesion.

Inventive Principle:
Principle #3Local quality

AI summary

A tape 60 includes a strip-shaped sheet 7, a plurality pairs of first media 8 and second media 9, and separating lines 43, 44. The first medium 8 and the second medium 9 are peelably stuck to the sheet 7 so as to be located adjacent to and spaced apart from each other in a longitudinal direction 16 of the sheet 7. The first separating line 44 is located between a pair of the first medium 8 and the second medium 9 in the longitudinal direction 16 and extends between one end 71 and the other end 73 of the sheet 7. The second separating line 43 is provided on a portion 95 of the sheet 7 which is located between a center M2 of the second medium 9 and one end 93 of the second medium 9 in a widthwise direction 17 and which extends from one end 91 to the other end 92 of the second medium 9 in the longitudinal direction 16. Each of the separating lines 43, 44 has a portion of the sheet 7 which is cut in its thickness direction or through which holes or the like is formed in the thickness direction.
