Hanging Lamp Cable Alignment Disk Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hanging lamps with asymmetrical weight distribution due to material tolerances and assembly issues often tilt undesirably, and existing solutions either require complex mechanisms or aesthetically unsatisfactory cable adjustments.
Innovation Solution
A simplified design where a disk-shaped element with a guide slot is integrated into the lamp housing, allowing for easy one-handed adjustment of the cable attachment point to align vertically over the lamp's center of gravity, using a rotary mechanism that can be fixed securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the cable attachment point is moved laterally to correct asymmetrical weight distribution, then the lamp alignment is improved, but the cable orientation becomes aesthetically unsatisfactory
Solution Approach 1:
The cable attachment point is made dynamically adjustable through a rotatable disk element with a guide slot. This allows the attachment point to be repositioned laterally by rotating the disk, enabling correction of asymmetrical weight distribution while maintaining the ability to restore the cable to a vertical aesthetic position. The dynamic adjustment mechanism resolves the contradiction by providing both alignment correction and aesthetic preservation.
2Manufacturing precision
If a complex suspension device with horizontal guide and clamping device is used to adjust cable position, then the lamp alignment is improved, but the device complexity increases
Solution Approach 1:
The adjustment function is merged directly into the lamp housing through an integrated disk element with a guide slot. This eliminates the need for separate complex suspension devices with horizontal guides and clamping mechanisms. The disk element combines the attachment function and adjustment function in a single compact component that is part of the lamp structure itself, significantly reducing overall device complexity while maintaining alignment precision.
Solution Approach 2:
The adjustment mechanism is extracted from a separate complex device and incorporated as a simple rotatable disk element with guide slot directly in the lamp housing. This extraction simplifies the overall system by removing unnecessary components and reducing the mechanical complexity of the suspension and adjustment system.
3Ease of operation
If a rotary mechanism is used to adjust the cable attachment point, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The rotatable disk element with guide slot provides a self-aligning mechanism where the guide slot naturally guides the cable attachment point to the correct lateral position during rotation. The geometry of the guide slot and disk combination automatically ensures precise alignment as the disk is rotated to the appropriate position, reducing the need for high-precision manufacturing tolerances while maintaining alignment accuracy.

AI summary
The lamp has a fixation area provided for fixing of a hanging element i.e. wire rope (2). The fixation area has a guidance slot aligned transverse to a longitudinal extension of the lamp, where an end area of the hanging element facing the lamp is guided into the guidance slot. The guidance slot is partially covered by a plate shaped element i.e. segment plate (5), with a slot designed radial to a rotary point, where the slot is movable over the guidance slot. The slot receives an end area of the hanging element and is movable into the guidance slot during rotation of the plate shaped element.
