Solution Overview
Problem
Conventional notebook computer handles lack sufficient mechanical strength and are structurally complex, leading to high manufacturing costs and susceptibility to salt mist corrosion, while being difficult to manufacture and carry due to their intricacy.
Innovation Solution
A notebook computer carrying device with a handle made of soft or hard plastic, featuring two telescopic members with movable components that form an inclination angle, allowing for easy handling and resistance to salt mist corrosion, simplifying the manufacturing process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional handles are made structurally intricate to achieve sufficient mechanical strength, then strength is improved, but device complexity increases and manufacturing costs increase
Solution Approach 1:
The patent employs composite material construction by integrating a telescopic mechanism within a plastic handle body. The handle combines a plastic outer shell with an internal telescopic structure comprising nested components, allowing the handle to achieve sufficient mechanical strength through the composite action of these materials rather than relying on complex metal structures. This resolves the contradiction by providing strength through material composition rather than structural intricacy.
2Ease of operation
If conventional handles are made telescopic and retractable to improve ease of carrying, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent implements a nested telescopic mechanism where handle components are arranged in concentric nested structures. The telescopic members are housed within the plastic handle body, with inner components sliding within outer components. This nesting arrangement provides the retractable functionality for ease of carrying while minimizing the overall structural complexity by efficiently packing the telescopic mechanism within the handle's form factor.
3Strength
If conventional handles are made of metal to achieve sufficient mechanical strength, then strength is improved, but resistance to salt mist corrosion worsens
Solution Approach 1:
The patent replaces traditional metal handle construction with a composite structure using plastic materials for the handle body and telescopic mechanism components. This material substitution maintains sufficient mechanical strength through the composite design while providing inherent resistance to salt mist corrosion that plastic materials possess, thereby resolving the contradiction between strength and corrosion resistance.
4Strength
If conventional handles are made structurally intricate to achieve sufficient mechanical strength, then strength is improved, but ease of manufacture worsens
Solution Approach 1:
The patent divides the handle into segmented components including the plastic handle body and separate telescopic mechanism elements. This segmentation allows each component to be manufactured independently using suitable processes, then assembled together. The telescopic mechanism is segmented into nested components that can be produced separately and integrated, simplifying the overall manufacturing process while maintaining the required mechanical strength through the assembled composite structure.

AI summary
A notebook computer carrying device includes a carrier, a handle, and two telescopic members disposed at two ends of the handle and each including a first component and a second component, with the first components formed by extending the ends of the handle outward, and the second components disposed on the carrier. The first and second components of each telescopic member are movably connected, and the first component slides in a displacement direction from a first position to a second position. The displacement direction is defined as the start direction of the first position. A horizontal plane is defined by connecting the two ends of the handle. A vertical plane is defined to extend outward in the direction in which the horizontal plane faces the center of the handle. The displacement direction extends from the horizontal plane to vertical plane and forms an inclination angle relative to the horizontal plane.
