Lid fitting for swingable mounting of a lid to a furniture body and furniture with such a lid fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover fittings for furniture require complex fastening mechanisms, making them difficult to attach and assemble efficiently.
Innovation Solution
A cover fitting with a base element having two fastening pins and one fastening hole, allowing for pivotable attachment to a furniture body using a single screw, with a swivel arm and front connection element to manage torque and simplify the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fastening mechanisms are used for attaching cover fittings to furniture bodies, then the attachment is secure and reliable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The fastening mechanism is segmented into two distinct functional components: fastening pins for torque absorption and a single fastening screw for fixation. This segmentation allows each component to perform its specific function optimally, simplifying the overall assembly process while maintaining secure attachment.
Solution Approach 2:
The torque-absorbing function is extracted from the fastening screw and assigned to dedicated fastening pins. This extraction eliminates the need for complex torque-resistant fastening mechanisms, allowing the screw to focus solely on fixation and significantly simplifying the assembly process.
2Reliability
If multiple fastening screws are used to attach the base element to the furniture body, then the attachment is more secure, but the assembly process requires more steps and tools
Solution Approach 1:
The fastening system is segmented into multiple fastening pins that collectively provide secure attachment through torque absorption, while only a single fastening screw is required for fixation. This segmentation maintains high reliability through the pins while dramatically improving productivity by reducing the number of screws needed.
Solution Approach 2:
The fastening pins act as intermediaries between the base element and the furniture body, absorbing torque and lateral forces. This intermediary function protects the fastening screw from torque loads, allowing it to perform its fixation function with a single screw rather than requiring multiple torque-resistant fasteners.
3Strength
If the fastening screw is used to absorb torque, then the attachment remains secure under load, but the screw is subjected to lateral forces that may compromise its fixation
Solution Approach 1:
The mechanical loads are segmented into two types: torque and lateral forces are absorbed by the fastening pins, while the fastening screw handles only the fixation function. This segmentation protects the screw from damaging lateral forces while maintaining secure attachment under torque loads.
Solution Approach 2:
The torque-absorbing function is extracted from the fastening screw and assigned to the fastening pins. This extraction eliminates lateral forces from the screw, ensuring reliable fixation while the pins provide the necessary torque resistance for secure attachment.
