Scissor Sheath Support Frame for Upright Safe Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scissors with working parts sheathed in a sheath are difficult to display statically due to their orientation on a surface, making the operating and sheathed parts less visible, and there is a risk of injury from the exposed working parts.
Innovation Solution
A scissor sheath with a chamber for the working part and a support frame that includes a base, support arms, and pins, allowing upright installation on a surface, enhancing visibility and safety by preventing pricking or cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the scissor is sheathed in a conventional sheath and placed on a table, then the working part is protected and safety is improved, but the operating part and sheath side facing the table are difficult to observe and static display is insufficient
Solution Approach 1:
The sheath transitions from a flat horizontal placement to a three-dimensional upright standing position through the support frame structure. The base provides horizontal stability while the vertical support arms elevate the sheath, creating a multi-dimensional display configuration that makes the operating part visible from multiple angles rather than being obscured by horizontal placement.
Solution Approach 2:
The support frame acts as an intermediary structure between the sheath and the table surface. Instead of the sheath directly contacting the table (which causes poor visibility), the support frame mediates by providing vertical support through pins entering chutes, allowing the sheath to stand upright with the operating part exposed and visible while maintaining stability through the base.
2Ease of manufacture
If the working part is exposed for display, then visibility is improved, but the risk of user injury from cutting or pricking increases
Solution Approach 1:
The sheath is segmented into distinct functional zones: the chamber portion that encloses and protects the sharp working part, and the support frame portion that provides upright positioning. This segmentation allows the working part to be contained within the protective chamber while the support structure provides visibility and stability, separating the protection function from the display function.
Solution Approach 2:
The working part is nested within the chamber of the sheath, which itself is supported by the support frame structure. This nested configuration allows the sharp working part to be concealed within the protective chamber enclosure while the overall assembly maintains an upright visible position through the support frame, achieving both protection and visibility simultaneously.
3Ease of manufacture
If the sheath is made upright for better display, then static display effect is improved, but the stability and ease of assembly may be compromised
Solution Approach 1:
The chutes are pre-formed in the sheath structure at predetermined locations and angles, and the pins are pre-positioned on the support frame. This preliminary configuration of the joining elements allows for straightforward assembly where the pins simply enter the chutes to establish the upright position, eliminating the need for complex alignment procedures or additional fastening steps that would compromise stability or ease of assembly.

AI summary
Disclosed is a scissor sheath, including a sheath and a support frame, wherein the sheath is a shell-like structure that creates an interior chamber. The sheath has two side parts, and each side part forms a chute. Each of the chutes stretches to the back edge of each corresponding side part. The support frame includes a base, two support arms and two pins, wherein the base connects each of the support arms, each of the pins is connected to each of the support arms, and the pins are laterally opposite each other. Each pin enters each chute, the sheath is erected on the top edge of an installation surface, and the supporting frame leans against the installation surface to provide support for the sheath.
