Bird Deterrent Lamp One-Dimensional Tilt Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird-deterrent lamps with complex and costly two-dimensional tilt switches risk disrupting air traffic and causing eye discomfort for humans due to upward light beam emission, necessitating a simpler and more directional control mechanism.
Innovation Solution
A lamp utilizing a single direction-dependent tilt switch with a simpler construction, optionally combined with additional switches, ensures the light source only emits when the lamp is positioned vertically, using mechanical or electronic switches connected in series with a manual switch or dimmer, and potentially incorporating a rotatable frame for automatic alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a two-dimensional tilt switch is used to control the light source, then the light beam direction can be controlled in multiple directions, but the construction becomes complicated and costly
Solution Approach 1:
The patent divides the tilt switch function into two separate one-dimensional switches: a first tilt switch for controlling vertical direction and a second tilt switch for controlling horizontal direction. Each switch has a simple construction with only one sensing element, avoiding the complexity of a single two-dimensional switch while achieving comprehensive directional control through their combined series connection.
Solution Approach 2:
The patent transitions from a single two-dimensional switch to two separate one-dimensional switches operating in different dimensional planes. The first tilt switch senses tilt in the vertical plane, while the second tilt switch senses tilt in the horizontal plane, together providing three-dimensional directional control through dimensional decomposition.
2Adaptability or versatility
If a two-dimensional tilt switch is used, then comprehensive directional control is achieved, but the volume of the switch increases
Solution Approach 1:
The patent segments the bulky two-dimensional switch into two compact one-dimensional switches. Each switch contains only a single tilt-sensitive element rather than a complex two-dimensional sensing mechanism, significantly reducing the volume of each individual switch while the combined volume remains smaller than a single two-dimensional switch would require.
3Ease of operation
If the lamp is made portable for bird deterrence, then mobility and ease of deployment improve, but the risk of unintended upward light emission increases
Solution Approach 1:
The patent implements an automatic safety mechanism where the two tilt switches continuously monitor the lamp's orientation and automatically interrupt the circuit to switch off the light source when improper positioning is detected. This self-service safety feature eliminates the need for user intervention or complex control systems, simply providing passive protection against upward light emission through the inherent tilt-sensing capability of the switches.
Solution Approach 2:
The patent prevents harmful upward light emission by using tilt switches that detect improper orientation before significant upward emission occurs. The switches are positioned and oriented to detect tilt angles that would lead to upward beam direction, interrupting the circuit in advance to prevent the harmful effect rather than correcting it after occurrence.

AI summary
The invention relates to a lamp, comprising a light source for generating a light beam in the direction of a main axis and a first direction-dependent tilt switch for controlling the light source depending on the angle between the main axis and the vertical, wherein the switching direction of the first tilt switch extends in a main plane which runs along the main axis. This enables the use of a tilt switch which functions in only one direction and has a much simpler construction than a switch which functions in two dimensions, such as in the prior art. Furthermore, such a switch has the advantage of a small volume, which advantage is also realized when more switches are used in the lamp. According to another preferred embodiment, the lamp comprises a housing and the housing is provided with marking means for marking the position of the lamp in which the main plane extends vertically.
