Light Well Body Locking Mechanism for Tool-Free Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light well body systems face challenges in quick and simple height adjustment and assembly, requiring complex and time-consuming processes, especially when loosening screws to adapt to different floor levels.
Innovation Solution
A light well body system with a locking element that can be manually adjusted between release and engagement positions, allowing for height adjustment without loosening screw connections, ensuring a secure and immovable connection to the wall, and featuring a locking mechanism that can be easily rotated and moved to facilitate assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light shaft body is connected to the wall with screw connections, then a secure connection is achieved, but height adjustment becomes complex and time-consuming requiring loosening screws
Solution Approach 1:
The connection system is segmented into a locking element with locking area, allowing the connection to be divided into adjustable segments. The locking element can be positioned at different locations along the locking area to achieve height adjustment without loosening screw connections, resolving the contradiction between secure connection and ease of adjustment.
Solution Approach 2:
The locking element is designed to be movable along the locking area during assembly, enabling dynamic adjustment of the light shaft body height. After positioning, the locking element secures the connection, providing both adjustability and stability without requiring screw loosening.
2Adaptability or versatility
If the light shaft body is made adjustable in height after wall connection, then floor level adaptation is possible, but assembly time and effort increase significantly
Solution Approach 1:
The locking element is preliminarily positioned along the locking area before final securing. This allows the light shaft body to be quickly adjusted to the correct height by simply moving the locking element to the appropriate position, without requiring complex adjustment procedures or additional tools, thus maintaining high assembly speed while achieving floor level adaptation.
3Productivity
If a locking mechanism is added to enable height adjustment without loosening screws, then assembly time is reduced, but device complexity increases
Solution Approach 1:
The locking element serves multiple functions: it provides the locking action to secure the light shaft body to the wall, enables height adjustment by being movable along the locking area, and maintains connection security when engaged. This multi-functionality reduces the need for separate adjustment mechanisms, thereby limiting the increase in device complexity while achieving faster assembly.
4Ease of operation
If the locking element is designed for manual movement between engaged and released positions, then tool-free operation is achieved, but the mechanism requires more manual manipulation steps
Solution Approach 1:
The locking element acts as an intermediary between the light shaft body and the wall, providing a simple manual interface for adjustment. By moving this single intermediary component between engaged and released positions, the operator can achieve height adjustment without tools, and the simple design minimizes the manipulation time required.

AI summary
A light well body system (5) is shown, comprising a locking element (30, 30') for connecting the light well body system (5) to a wall of a building, and a light well body (10) with a locking area (20, 20') for receiving a part of the locking element (30, 30'), wherein the locking element (30, 30') can be connected to the wall such that the locking element (30, 30') is essentially immovable parallel to the surface of the wall, and is designed such that in an engagement position it engages in an engagement recess (25, 25') of the locking area (20, 20') in such a form-fitting manner that the light well body (10) is essentially immovably connected to the wall along a longitudinal direction of the locking area (20, 20'), and that the The locking element (30, 30') in a release position allows the light shaft body (10) to be moved relative to the locking element (30,30') essentially along the longitudinal direction of the locking area (20, 20').
