Laterally Adjustable Hook Assembly for Precise Splitboard Joining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interlocking hook systems for joining planar surfaces, such as splitboards, are not adjustable, leading to time-consuming and error-prone mounting processes that can weaken the materials and result in mechanical failure.
Innovation Solution
A laterally adjustable hook system that allows for adjustments without redrilling, featuring a unitary body with oblong, beveled slots and a nose portion, enabling precise fitting and secure attachment of planar parts through wedge nuts and set screws, accommodating manufacturing variability and wear.

Engineering Contradiction Analysis
1Productivity
If non-adjustable hooks are used to join planar surfaces, then the mounting process becomes time-consuming and error-prone, but the hook structure remains simple
Solution Approach 1:
The hook incorporates an adjustable mechanism that allows the mounting position to be dynamically changed after initial installation. The slot-receiver design enables the hook to be laterally adjusted along the slot to achieve precise positioning, transforming a static mounting system into a dynamic one that can adapt to positioning errors or wear.
Solution Approach 2:
The mounting system is divided into separate functional components: the hook body, the slot in the first planar surface, and the receiver that engages with the slot. This segmentation allows independent adjustment of the hook position along the slot without affecting the overall mounting structure or requiring redrilling.
2Measurement precision
If redrilling is performed to adjust hook placement, then precise positioning can be achieved, but the planar parts are weakened and mechanical failure risk increases
Solution Approach 1:
Instead of creating permanent fixed holes through redrilling, the system uses a dynamic adjustment mechanism where the receiver can slide along the slot and be secured at different positions. This allows precise hook placement to be achieved without additional drilling operations, thereby preserving the structural integrity of the planar parts.
Solution Approach 2:
The slot acts as an intermediary element between the hook and the planar surface. Rather than requiring direct rigid fixation through multiple holes, the slot provides a flexible connection path that allows positioning adjustment while maintaining structural strength, eliminating the need for redrilling.
3Adaptability or versatility
If adjustable hooks with slots and receivers are used, then positioning flexibility is improved, but the hook mechanism becomes more complex
Solution Approach 1:
The adjustable mechanism is segmented into simple, discrete components: a slot cut in the planar surface and a receiver attached to the hook that engages with the slot. This segmentation keeps each component simple while providing collective adaptability, avoiding the need for complex adjustment mechanisms.
Solution Approach 2:
The slot-receiver mechanism serves multiple functions: it provides positioning flexibility during installation, allows for adjustment after installation, and accommodates manufacturing tolerances. This multi-functionality is achieved through a simple geometric design rather than complex mechanisms.

AI summary
Laterally adjustable hooks may be used to join two or more substantially planar parts, such as two halves of a splitboard. In an embodiment, a laterally adjustable hook comprises a unitary body having a top surface, a bottom surface, a main portion and a nose portion, with the main portion comprising at least one oblong, beveled slot and the nose portion extending from an end of the main portion. A screw or wedge nut may be used to apply pressure to edges of the oblong, beveled slot, and a pair of set screws may contact and laterally secure the wedge nut.
