Handle Base Profile Assembly for Stable T-Nut Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handles for attaching to base bodies often require complex structures and significant assembly effort, lacking in simplicity and stability in their attachment mechanism.
Innovation Solution
A handle design featuring a basic profile with inclined receiving sections and sliding blocks with threaded holes, allowing for easy assembly and rigid fixation to a base body through tensile stresses generated by screwing the sliding blocks into place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a handle is attached to a base body using conventional methods, then the handle can be fixed to the base body, but the structure becomes complex and assembly requires significant effort
Solution Approach 1:
The handle is divided into a basic profile and multiple sliding blocks that can be independently manufactured and then assembled. The sliding blocks are inserted into receiving sections of the basic profile, allowing separate production of components that are then easily combined through a simple insertion and clamping process.
Solution Approach 2:
The sliding blocks are inserted into receiving sections of the basic profile, with one component nested within another. This nesting arrangement simplifies assembly as the sliding blocks slide into place within the basic profile structure without requiring complex fastening mechanisms.
2Reliability
If conventional attachment methods are used, then the handle can be fixed to the base body, but the attachment lacks rigid stability
Solution Approach 1:
The sliding blocks are designed with outer profile cross-sections adapted to the inner profile cross-sections of the receiving sections, creating a pre-configured fit. This preliminary geometric matching ensures that when the sliding blocks are inserted and clamped, they immediately achieve proper alignment and rigid stability without requiring additional adjustment or complex positioning mechanisms.
Solution Approach 2:
The profile cross-sections of the sliding blocks and receiving sections are designed with complementary curved or angled surfaces. This geometric adaptation creates a form-fitting connection that enhances stability through surface contact and mechanical interlocking, providing rigid attachment through the shape design itself rather than through complex fastening systems.
3Strength
If screws are used to attach the handle, then the handle can be fixed to the base body, but pressure points are created during attachment
Solution Approach 1:
Instead of using screws that create concentrated pressure points at single locations, the attachment force is distributed across the entire surface area of the sliding blocks' contact surfaces with the base body. This dimensional transition from point contact to surface contact eliminates pressure points while maintaining strong attachment through distributed clamping force generated by the sliding blocks.

AI summary
A handle 1 can be attached to a base body 2 by screws 3 and comprises a base profile 4 with two receiving sections 5 and at least two T-nuts 6, each of which has a threaded bore 7 for receiving one of the screws 3. Each T-nut 6 is inserted into a receiving section 5 and can be clamped in place by screwing a screw 3, which passes through the base body 2, into the threaded bore 7 in the receiving section 5. Clamping the T-nuts 6 generates tensile stresses Z, which pull the base profile towards the surface 8 of the base body 2 and thus fix it to the base body 2.
