Solution Overview

Problem

Existing lifting devices for tables or chairs face issues with cable management, as cables can become damaged or tangled with screw rods due to limited internal space, leading to instability and reduced service life.

Innovation Solution

A lifting device with a cable management component featuring a spiral coiled cable unit reeled on a cable management component, which is arranged in parallel with the screw rod, allowing for elastic deformation and preventing tangling or rubbing with the screw rod, thus stabilizing the cable and enhancing the device's service life and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cable is disposed in the lifting device, then the cable can be connected to external controller, but the cable is not easy to be stably positioned and may rub or be tangled with the screw rod

Engineering Contradiction:

Improvecable positioning stabilityVSAvoidcable damage risk

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A cable management component is introduced as an intermediary element between the cable and the screw rod. This component guides and restrains the cable, preventing direct contact and potential tangling with the rotating screw rod, thereby resolving the positioning stability issue while maintaining cable connectivity

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The cable is designed with a spiral coiled structure that provides flexibility and elastic deformation capability. This flexible configuration allows the cable to accommodate movement and positioning changes without rigid constraints, reducing the risk of damage from rubbing or tangling

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If the cable is moved with the connecting end, then the cable can follow the linkage member movement, but the cable may be damaged or the lifting device may not be able to operate

Engineering Contradiction:

Improvecable movement adaptabilityVSAvoiddevice operation reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The spiral coiled cable structure provides inherent flexibility and elastic deformation, allowing the cable to adapt to the movement of the linkage member while maintaining structural integrity. This flexibility enables the cable to follow the connecting end movement without damage

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The cable management component acts as a mediator that guides the cable's movement path, ensuring the cable moves smoothly with the linkage member while preventing harmful contact with the screw rod, thus maintaining device operation reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the spiral coiled cable unit is reeled on the cable management component, then the cable is restrained to be kept in vertical status, but the cable management component occupies additional space in the outer pipe

Engineering Contradiction:

Improvecable vertical status stabilityVSAvoidcable management component volume

Core Design Contradiction:

Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The spiral coiled cable structure itself provides the vertical restraining function through its geometric configuration. The coiled structure naturally maintains vertical alignment when reeled on the cable management component, achieving stability without requiring additional complex spatial mechanisms

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A lifting device with a cable management is provided. The lifting device includes: an outer pipe, an actuation mechanism, a linkage member, a cable, and a cable management component. The actuation mechanism is accommodated in the outer pipe and has a motor and a screw rod. The linkage member is accommodated in the outer pipe and mutually screw-fitted with the screw rod to operate, and moves relative to the outer pipe. The cable has a spiral coiled cable unit. A shaft core line in parallel with the screw rod is defined by the spiral coiled cable unit. The cable management component is disposed in the outer pipe and in parallel to the shaft core line. The spiral coiled cable unit is reeled on the cable management component. Accordingly, the cable may be stably positioned and the cable may be prevented from rubbing or being tangled with the screw rod.
